Understanding Modern Optical Transport Solutions: A Technical Comparison

The telecommunications landscape has undergone a remarkable transformation over the past decade. Network operators and enterprises now face unprecedented demands for bandwidth, speed, and reliability. This evolution has driven the development of sophisticated optical transport solutions that form the backbone of our modern digital infrastructure.

When evaluating different transport network technologies, understanding their capabilities, limitations, and optimal use cases becomes crucial for making informed decisions. Let's explore the current state of optical transport solutions and examine how various technologies stack up against each other.

The Foundation of Modern Optical Networks

Modern optical transport systems represent a significant leap from traditional copper-based networks. These systems leverage light wavelengths to carry vast amounts of data across fiber optic cables with minimal signal degradation. The fundamental advantage lies in their ability to transmit multiple channels simultaneously while maintaining signal integrity over long distances.

Traditional transport methods relied heavily on time-division multiplexing (TDM), which allocated specific time slots for different data streams. However, this approach has limitations when dealing with the explosive growth in data traffic. Modern optical solutions address these constraints through wavelength-division multiplexing techniques, allowing multiple data streams to coexist on the same fiber infrastructure.

The shift toward packet-based transport has also revolutionized how networks handle diverse traffic types. Unlike circuit-switched networks that required dedicated paths, packet-based systems offer greater flexibility and efficiency in bandwidth utilization.

Dense Wavelength Division Multiplexing: The Powerhouse Solution

DWDM technology stands as one of the most significant advances in fiber optic transport. This technology enables network operators to transmit multiple optical signals simultaneously over a single fiber strand, with each signal operating on a different wavelength.

The technical specifications of DWDM systems are impressive. Modern implementations can support 80 to 160 channels, with each channel capable of carrying 10 Gbps, 40 Gbps, or even 100 Gbps of data. This translates to total capacity exceeding 10 terabits per second on a single fiber pair.

What makes DWDM particularly valuable is its ability to upgrade existing fiber infrastructure without requiring new cable installations. Network operators can increase capacity by simply adding more wavelengths to their existing fiber plant. This approach significantly reduces capital expenditure while maximizing the return on previous fiber investments.

The technology excels in long-haul applications where distance and capacity requirements are substantial. Metropolitan area networks and submarine cable systems heavily rely on DWDM to meet their demanding performance requirements.

Coarse Wavelength Division Multiplexing: The Cost-Effective Alternative

CWDM offers a more budget-friendly approach to wavelength division multiplexing. While it provides fewer channels compared to DWDM systems, typically supporting 8 to 18 wavelengths, it delivers substantial cost savings for applications that don't require maximum capacity.

The key advantage of CWDM lies in its simplified architecture. The technology uses wider channel spacing, which reduces the precision requirements for optical components. This translates to lower equipment costs and simplified network management.

CWDM systems typically serve shorter distances, making them ideal for metropolitan area networks, enterprise campus environments, and regional connectivity applications. The technology provides an excellent balance between performance and cost-effectiveness for organizations with moderate bandwidth requirements.

Connectivity Infrastructure: The Unsung Heroes

Behind every successful optical transport deployment lies a robust connectivity infrastructure. Fiber optic patch cords serve as the critical links connecting various network elements, from transceivers to patch panels and cross-connects.

The quality of these connections directly impacts overall network performance. High-quality patch cords ensure minimal insertion loss and maintain signal integrity throughout the optical path. Poor connections can introduce unwanted reflections and signal degradation that compromise the entire system's performance.

Modern data centers and telecommunications facilities increasingly rely on MPO/MTP patch cords for high-density applications. These multi-fiber connectors can accommodate 12, 24, or even 48 fibers in a single connector, dramatically reducing the space required for fiber management while maintaining excellent optical performance.

Comparing Transport Technologies: Performance Metrics

When evaluating different optical transport solutions, several key performance indicators warrant consideration:

Capacity and Scalability: DWDM systems offer the highest capacity potential, supporting terabit-scale transmission on a single fiber. CWDM provides moderate capacity suitable for many applications, while traditional transport methods offer limited scalability.

Distance Capabilities: Long-haul applications favor DWDM due to its superior optical performance and amplification capabilities. CWDM works well for shorter distances, typically up to 80 kilometers without amplification.

Cost Considerations: CWDM systems generally require lower initial investment, making them attractive for cost-sensitive deployments. DWDM systems, while more expensive initially, offer better long-term scalability and lower cost per bit for high-capacity applications.

Complexity and Management: CWDM systems typically require less complex management due to their simpler architecture. DWDM systems offer more sophisticated monitoring and management capabilities but require more specialized expertise.

Future-Proofing Your Network Investment

The rapid evolution of optical transport technology demands careful consideration of future requirements. Coherent detection technology has emerged as a game-changer, enabling higher data rates and improved performance over existing fiber infrastructure.

Software-defined networking (SDN) concepts are also making their way into optical transport, providing greater flexibility in network management and resource allocation. These developments suggest that future optical transport solutions will offer even greater efficiency and programmability.

Network operators should consider their growth projections and application requirements when selecting transport technologies. A phased approach often works best, starting with cost-effective solutions and upgrading to higher-capacity technologies as demands increase.

Making the Right Choice for Your Network

Selecting the appropriate optical transport solution requires careful analysis of current requirements and future growth projections. Organizations with immediate high-capacity needs and sufficient budget may benefit from DWDM implementations. Those with moderate requirements and cost constraints might find CWDM solutions more suitable.

The supporting infrastructure, including fiber optic patch cords and connectivity hardware, plays an equally important role in overall system performance. Investing in high-quality components ensures reliable operation and maximizes the return on your optical transport investment.

Understanding these technologies and their trade-offs enables network professionals to make informed decisions that align with their organization's technical requirements and financial constraints. The key lies in matching the right technology to the specific application while maintaining flexibility for future expansion.

Conclusion

Modern optical transport solutions offer unprecedented capabilities for handling today's demanding network requirements. Whether implementing DWDM for maximum capacity, CWDM for cost-effective solutions, or hybrid approaches that combine multiple technologies, success depends on understanding each technology's strengths and limitations.

The continued evolution of transport network technology promises even greater capabilities in the coming years. By staying informed about these developments and making thoughtful technology choices today, organizations can build robust, scalable networks that serve their needs well into the future.

The foundation of any successful optical transport deployment rests on quality components and proper planning. From the selection of appropriate multiplexing technology to the choice of connectivity infrastructure, every decision impacts the overall network performance and reliability.

How much do you know about 25G WDM Technology of 5G Fronthaul?

5G fronthaul is the essential part of 5G network transmission. The fronthaul technology solution based on wavelength division multiplexing (WDM) has become the focus of the industry. The article presents and evaluates 5G fronthaul demand on 25G WDM technology, typical types of 5G fronthaul WDM technical solutions, 25G LAN-WDM technical solutions, and its standardization.

1. 25G WDM technology-An Urge for 5G Fronthaul

From the technical point of view, 5G features high transmission speed(from 25Gbit/s to 100Gbit/s even 200G), low latency with 1 millisecond, and high clock-synchronization accuracy. Since a large number of AAUs in the 5G fronthaul are required, the cost of accessing the bearer network will increase significantly.

The 5G fronthaul network will widely adopt the eCPRI interface, which requires a data speed of 25G in the configuration of 100MHz spectrum, 64T/64R antenna, and 16 downstream/upstream 8 streams. Multiple 25G Ecpri interfaces need to be deployed in 5G fronthaul when the wireless spectrum is broader.

There are many solutions for 25G WDM technology that can be applied to 5G fronthaul, including DWDM, CWDM, and LAN WDM.

2. Mobile Fronthaul Network Structure Based on 25G WDM

According to the differences in equipment, mobile fronthaul optical network connectivity structure based on WDM technology can be divided into three types: active WDM connectivity, semi-active WDM connectivity, and passive WDM connectivity. Figure 2 shows the three types of structure.  

● Active WDM Connectivity

For the type of fully active WDM network, its central office also called ATU-C (ADSLTransceiverUnit-Centroloffice) and remote data station are both active equipment with clear professional interfaces and integrated multi-traffic bearer access. But the power supply and installation of remote equipment have to be considered.

● Semi-Active WDM Connectivity

For the semi-active WDM network structure, its central office is active equipment while the remote data station is simplified as WDM optical transceiver and passive multiplexer & demultiplexer. This type needs to be confirmed that the WDM optical module can be installed on the data transport equipment.

● Passive WDM Connectivity

Central office and remote data station for the third type are both with passive equipment, also being simplified as WDM optical transceiver and passive multiplexer & demultiplexer, which need to been confirmed their installations on data transport equipment. Therefore, from the perspective of network construction, operation, and maintenance, the first 2 types of mobile fronthaul Network structure are preferred over the third one in reality.

3. 5G Fronthaul solution based on 25G DWDM

25G DWDM technology can be applied in fixed wavelength and tunable wavelength according to the working wavelength of the laser, as shown in Figure 

● Segments of 25G DWDM Technology

DWDM technology used in tunable wavelength has been widely utilized in the optical network of 10G, 40G, and 100G. But it is still struggling to meet the demand on massive and cost-sensitive application situations of the metro access layer. There are many technical solutions for realizing tunable lasers, including DFB array, DBR, DS DBR, MG-Y, SG DBR, VCSEL, ECL, silicon optical micro-ring cavity and V-shaped coupling cavity, etc., all controlled by temperature, current, and mechanics.

Cost-effective optical modules using DWDM technology with tunable wavelength include those with fully tunable broadband C-band and partly tunable narrowband C-band. Nevertheless, the latter enjoys a more obvious cost advantage over the former and some companies specialized in the optical transceiver and optical component have launched their related products series, which is available on the current market.

The Advantage of CWDM in Metropolitan Area Network

Due to the fast improvement of information benefits, the speed of system union is quickening, MAN is turning into a focal point of system development, showcase rivalry weight makes the telecom administrators increasingly delicate to the expense of the system. Gone for the interest of the market, ease MAN CWDM items emerge right now.

With full range CWDM group (FCA) vivaciously advance of CWDM Technology and ITU-T for the institutionalization of CWDM, it makes CWDM innovation hardware producers and administrators be the focal point of consideration. The ITU-T fifteenth the group through CWDM wavelength matrix of standard G.694.2, and become an achievement in the historical backdrop of the advancement of CWDM innovation. The fifteenth group likewise advances the meaning of CWDM framework interface right application draft standard. Shanghai chime and different organizations in China in the institutionalization of CWDM innovation likewise has made a certain commitment; pertinent residential guidelines are additionally under talk.

As the development of the market request and the institutionalization of CWDM innovation quickly, numerous correspondence hardware makers, for example, Nortel, Ciena, Huawei, Alcatel Shanghai chime (asb), fire system created related items and add a wide scope of utilization in the market.

CWDM the framework is a minimal effort WDM transmission innovation towards MAN access layer. On a fundamental level, CWDM is utilizing optical multiplexer to various wavelengths of light to reuse the sign to single fiber optic transmission, at the connection of the less than desirable end, with the guide of photolysis of multiplex fiber blended sign is disintegrated into various wavelength signal, associated with the comparing getting gear. What's more, the primary the distinction with DWDM is that: contrasted with the 0.2nm with 1.2 nm wavelength separating in DWDM framework, CWDM Wavelength Spacing is more extensive, wavelength dividing of 20 nm industry acknowledged measures. Every wavelength of the band spread the single-mode fiber arrangement of O, E, S, C, L band, etc.

In view of CWDM framework has wide wavelength dividing and low interest to specialized parameters of the laser. Since wavelength dividing up to 20 nm, the framework most extreme wavelength move can reach - 6.5℃~+6.5 ℃, the outflow the wavelength of laser accuracy can be up to +/ - 3nm, and the working temperature run (- 5℃~70℃), wavelength float brought about by temperature change is still in the admissible range, laser without temperature control the instrument, so the structure of the laser significantly disentangled yield improvement.

Moreover, the bigger wavelength separating implies recuperation gadget/arrangement of multiplexer structure is significantly disentangled. CWDM framework, for instance, the CWDM Filter layer covering layer can be diminished to 50, and DWDM arrangement of 100 GHZ channel film covering layer number is around 150, bringing about expanded yield, cost decrease, and the channel provider has enormously expanded challenge. CWDM channel cost not exactly the expense of DWDM channel about over half, and with the expansion of computerization generation innovation, it will be further decreased.

Still CWDM situating the short separation transmission in the metropolitan zone organize (inside 80 km), and the channel rate is commonly not more than 2.5 Gbps, so there is no requirement for light intensification, scattering, nonlinear and different contemplations in the transmission lines, at that point you can make the framework is streamlined.

By methods for a portion of these, by growing wavelength dispersing and improving hardware, the expense of optical channel made the CWDM framework unit can be diminished to 1/2 or even 1/5 of the DWDM framework, it has solid focal points in the metropolitan territory system access layer.

How to Future-Proof Your Telecommunications Network in 2025

In today's rapidly evolving digital landscape, telecommunications networks face unprecedented demands. With the explosion of IoT devices, cloud services, and bandwidth-intensive applications, organizations must plan for tomorrow's requirements today. Future-proofing your network isn't just a technical necessity—it's a strategic business imperative that can spell the difference between leading your industry or struggling to keep pace.

Understanding Today's Telecommunications Challenges

Before diving into solutions, let's examine the challenges modern networks face:

Exponential data growth: Global data creation is projected to exceed 180 zettabytes by 2025, more than triple the amount from 2020.

Increasing connectivity demands: Remote work, smart buildings, and connected devices are straining existing infrastructure.

Security vulnerabilities: As networks expand, potential attack surfaces grow proportionally.

Operational efficiency: Maintaining complex systems requires significant resources unless properly designed.

"Most organizations are still operating with infrastructure designed for yesterday's requirements," notes telecommunications expert Mark Chen. "The coming wave of applications will overwhelm unprepared networks."

Key Strategies for Future-Proofing Your Network

1. Embrace Scalable Infrastructure Design

Future-ready networks prioritize scalability from the ground up. This means implementing modular systems that can expand without requiring complete redesigns. Modern infrastructure approaches include:

Disaggregated network architecture: Separating hardware and software components allows for independent upgrades.

Software-defined networking (SDN): Centralizing network control and programmability enables rapid adaptation to changing requirements.

Network virtualization: Creating virtual versions of physical network resources improves flexibility and resource allocation.

These approaches provide the foundation necessary to accommodate growth without disruptive overhauls.

2. Upgrade to High-Capacity Fiber Backbones

Fiber optics remain the gold standard for telecommunications backbones. When upgrading your infrastructure, consider:

Higher-density cabling systems: Modern fiber optic patch cords support greater bandwidth in smaller physical footprints.

Advanced connector technologies: Latest-generation fiber optic adapters reduce signal loss and improve reliability.

Pre-terminated solutions: Factory-terminated assemblies ensure consistent performance and faster deployment.

The migration from copper to fiber—and from older fiber to newer specifications—delivers significant performance improvements while future-proofing your physical layer.

3. Implement Wavelength Division Multiplexing Technologies

Wavelength division multiplexing (WDM) technologies dramatically increase the capacity of existing fiber infrastructure by transmitting multiple data channels simultaneously over the same fiber. Consider implementing:

CWDM (Coarse Wavelength Division Multiplexing): Cost-effective solution for modest bandwidth increases, using widely spaced wavelengths.

DWDM (Dense Wavelength Division Multiplexing): Higher-capacity solution supporting up to 96 channels on a single fiber.

FWDM (Filtered Wavelength Division Multiplexing): Specialized multiplexing for specific applications with unique wavelength requirements.

These technologies allow organizations to multiply fiber capacity without laying additional cables—an essential strategy for urban environments or facilities with limited pathways.

4. Adopt MPO/MTP Technology for High-Density Environments

Multi-fiber Push-On/Mechanical Transfer Push-on (MPO/MTP) connectors are revolutionizing high-density environments:

Simplified cable management: A single MPO connector can replace up to 24 traditional fiber connections.

Migration path to higher speeds: MPO/MTP infrastructure supports seamless transitions from 10G to 40G, 100G, and beyond.

Reduced footprint: High-density connectivity in data centers and telecommunications rooms maximizes space efficiency.

"Organizations implementing MPO/MTP technology today are positioning themselves for tomorrow's multi-terabit applications," explains telecommunications architect Sarah Johnson.

5. Build Intelligence Into Your Network

Smart networks allow for proactive management rather than reactive troubleshooting:

Automated monitoring systems: Continuous performance tracking identifies potential issues before they affect service.

Artificial intelligence analytics: Pattern recognition helps predict and prevent network failures.

Self-healing configurations: Advanced networks can reroute traffic around problems automatically.

Intelligent networks reduce downtime and maintenance costs while improving overall reliability—critical factors in competitive environments.

Implementation Roadmap: A Phased Approach

Future-proofing doesn't happen overnight. Consider this realistic implementation timeline:

Assessment (1-2 months): Document current infrastructure and identify gaps between current capabilities and future requirements.

Design (2-3 months): Develop a comprehensive architecture incorporating the technologies discussed above.

Pilot implementation (3-4 months): Test new technologies in controlled environments before full deployment.

Phased rollout (6-18 months): Gradually implement changes to minimize disruption to operations.

Continuous improvement: Establish regular review cycles to identify emerging technologies and evolving requirements.

Cost Considerations and ROI

While future-proofing requires investment, the returns typically justify the expenditure:

Avoided replacement costs: Building properly the first time eliminates costly rip-and-replace projects.

Reduced downtime: Reliable networks minimize productivity losses and customer impacts.

Competitive advantage: Organizations with superior connectivity can deploy new services faster than competitors.

Energy efficiency: Modern equipment typically consumes less power while delivering higher performance.

A telecommunications consultancy recently found that organizations investing in future-proofed infrastructure saved an average of 32% on five-year total cost of ownership compared to those making incremental upgrades.

Conclusion: The Time to Act Is Now

As we navigate through 2025, the telecommunications landscape will continue evolving at unprecedented speeds. Organizations that prepare today for tomorrow's requirements will maintain competitive advantages, operational efficiency, and the agility needed to adopt emerging technologies.

Future-proofing your telecommunications network isn't simply about installing the latest equipment—it's about creating a flexible, scalable foundation that can adapt to changing requirements without requiring wholesale replacement. By implementing the strategies outlined above, you'll position your organization for success regardless of how the technological landscape evolves.

Remember: The most successful networks are those designed not just for today's requirements, but tomorrow's possibilities.

White Paper: CWDM + DWDM = Increased Capacity

One way of increasing capacity in fiber optic links is to add DWDM over existing CWDM

April 2023

by Robert Isaac

Ghostwritten by Scott Mortenson

For years, service providers have been using Coarse Wavelength Division Multiplexing (CWDM) to increase the capacity of fiber optic links. CWDM filters offer up to 18 ITU (International Telecommunication Union) defined wavelengths and has been an ideal way to transport 1Gbps and 10Gbps circuits over a single fiber span.

What we are seeing now seems to be an uphill climb for CWDM applications. There appears to be a bandwidth growth requirement, and decreased support for CWDM from some equipment manufacturers.

With CWDM support from manufacturers dwindling and the need for capacity increasing at an exponential rate, the question becomes “How do we increase the capacity without forklifting the existing CWDM?”

One answer can be using DWDM over the existing CWDM.

Figure 1

The Concept

Because CWDM is built with channels that are spaced 20nm apart and often have a 10-13nm passband per wavelength (see Figure 1 above), DWDM makes a lot of sense. DWDM filters are built with much smaller channel spacing (.4nm/.8nm/1.6nm), so these wavelengths can be combined and will pass through the ~13nm passband of CWDM channel. For this example, we will focus on standard DWDM filter channels that are in the C-Band (1525nm-1565nm) spectrum and 100Ghz-spaced as this is the most common and supported DWDM application.

If it is warranted this same principle can be applied using DWDM channels in the L-Band (1570nm-1610nm) as well as using channels that are only 50Ghz-spaced to increase channel count and density, and be easily supported with tunable SFP+ optics.

Figure 2

Figure 2 shows how cascading DWDM filters over an existing CWDM span would connect. In this example we use a standard, off the shelf, DWDM filter that is equipped with 8 channels (ITU Ch 52-59).

Figure 3

Figure 4

Figures 3 and 4 show how 20 DWDM channels could be added across the 1530nm CWDM port and 30 DWDM channels can be added using the 1550nm CWDM port using C-band channels. We could apply this same philosophy to the 1570nm, 1590, and 1610nm ports as well but would require L-Band DWDM channels which aren’t widely supported today.

The Challenge

Now that we know a standard 8 Channel CWDM can be expanded to include another 50 channels you may be thinking “What are the potential downsides to using DWDM over CWDM?” and that would be a very good question to ask.

This concept has been available for many years and hasn’t become part of the mainstream deployment strategy for many network operators. Why not? The only limitation to using this concept from a performance standpoint is the added insertion loss of having both the CWDM and DWDM filters between the transceivers.

Figure 5

Figure 5 shows the logical end-to-end for 8 channels of DWDM over an existing CWDM connecting two sites 30km apart. To keep losses lower, we will limit the new channels being added to 8 DWDM channels. Understanding that 10G DWDM optics have an overall power budget of 23db, we can see that adding the DWDM filters brings the overall link loss to 21.5db which falls just inside the power budget.

Because DWDM optics are built for longer reaches with higher power budgets — and CWDM is often used on shorter fiber spans, say under 30km — the insertion loss should be a non-issue. And if the loss is an issue, DWDM channels can be amplified (unlike CWDM), so placing a low-cost EDFA between the CWDM and DWDM filters could help extend the reach well beyond even 30km.

Reluctance to this concept also seems to come from not fully understanding the simplicity of passive WDM or even how to manage the engineering, installation, records, and inventory for having both technologies within the same span. If those challenges can be overcome, overlaying DWDM onto your existing CWDM can be a very efficient and cost-effective way to respond to the exponential need for bandwidth we are facing in today’s technology.

For network operators and service providers who have made a significant investment in CWDM and facing the need for bandwidth growth, this concept should be considered. Passive DWDM filters can be deployed quickly without impacting existing traffic, are a very low-cost alternative to complex active systems, and can equip your network for the future in very short order. Add the operational efficiency of 10G tunable DWDM optics, and this could be a home run for your network.

Demystifying DWDM for the DCI

If it is so easy and inexpensive, why aren’t all the data centers defaulting to using this on every fiber end? Well, that’s where things get a little tricky.

Whenever you say “DWDM” to a Data Networking person (and even some Service Provider engineers), their default reaction tends to go straight for large, complex, and expensive DWDM systems. Like Reconfigurable Optical Add Drop Multiplexing (ROADM) arrangements that are completely automated and perform optical switching, sub-signal aggregation, and even some L2 functions.

The truth is, DWDM is simply the combination and separation of circuits by wavelength — and only a small part of those larger systems. It is the basic technology that allows users to put 40+ distinct circuits on a given fiber, then separate them at the far end to connect to the individual switch ports.

As stated in the previously, this is often done passively, requiring no electrical power, software, annual maintenance agreement, etc. — and at a fraction of the cost of those more complex active systems.

So again, I ask: “Why aren’t more data center interconnects using this technology?”

Well, DWDM system design — or transport engineering — is usually not taught during Data Networking education courses. DWDM or transport are often thought of as completing ways of architecting a network, which means there are usually two camps: You are either a Data Network Engineer, or a Transport Engineer. Either way, one typically needs the other at some point in their network.

This is not to say you don’t need complex, software-controlled transport devices in your network. The truth is you likely do. What we are singling out here are a few applications where you can get what you need: Fiber capacity between two places quickly, inexpensively, and without sending anyone to school to get certified.

These applications can be:

• Point-to-Point Data Center Interconnects (DCI) on leased, or owned fiber. • Connections between campus facilities. • Network facilities between rooms or floors.

Using Passive DWDM can:

• Reduce or eliminate leased or new fiber builds. • Maximize the data rate per-fiber of installed fiber plants. • Drastically reduce Capex cost of high-capacity switches, complex DWDM systems, and reliance on service providers to maintain the connections. • Increase capacity of DCI connections in days not months.

How can we do this in a way we can understand?

It really comes down to Optical Link Engineering.

If you take the physical map of your network and zoom in on one span where there is a capacity bottleneck, it becomes a lot easier. For simplicity’s sake, we will focus on connecting 10G switch ports, across a single span between 2km and 50km long, making the math fairly simple.

For these locations, we just need to focus on two primary factors: Link Budget vs Link Loss, and Dispersion.

Link Budget vs. Link Loss

Every optic or transceiver has a minimum transmit power, and a minimum receiver sensitivity. By subtracting these two values, you are left with the link budget — or the total amount of power loss the signal can experience and still be legible by the receiver.

In a standard connection, you would calculate (or measure) the total loss of the fiber, patch panels, cassettes, and splices between the two optics. And if that is less than the link budget, then it should work . . . right?

Passive DWDM only adds a little more math to the Link Engineering. The optics at each end would need to be specific DWDM optics, and the filters will add more insertion loss at each end — but it is still, pretty much the same math.

For 10G DWDM optics, the link budget is typically in the 23db range. If a fiber span, with DWDM filters, has less than 23db of loss, the link should work. It’s simple math.

Or is it?

Dispersion

Another important factor we account for is Chromatic Dispersion (CD). This is a characteristic of single-mode fiber where, as a signal travels along a fiber route, it spreads out and can arrive at the far end slightly ahead or slightly behind schedule, making it difficult to be deciphered by the receiver.

The optics we are using will also establish how much dispersion it can tolerate before the signal becomes undetectable. This value is typically measured in picoseconds per kilometer per nanometer (ps/km/nm) or even simply by the optic’s distance rating. For instance, a DWDM optic-rated for 80km is often limited to 1360 ps/nm/km of dispersion. This is calculated based on traveling 80km on SMF28 type fiber with a CD rating of approximately 17 ps/nm/km.

So, there you have it. If your link falls inside the specifications defined by the optics on each end, you can deploy passive DWDM to maximize the capacity of your fiber plant, and save loads of time and money.

But what if the span exceeds the link budget or dispersion rating? No problem! The addition of Erbium Doped Fiber Amplifiers (EDFA) — to boost the signal power and/or passive Dispersion Compensation Modules (DCM) to account for excess dispersion between the DWDM filters — can help extend the reach and ensure the optics on each end perform to expectation to years to come.

Often when Transport Engineers speak to Data Network Engineers, it can seem like they are speaking different languages. That is to be expected. Specialized jargon or terminology, approaches to problems, and education can be vastly different.

If what your network truly needs is fiber capacity, lower cost of fiber infrastructure, and flexibility of lightning-fast circuit turn-up, passive and even amplified DWDM networks could be the perfect solution.

The 40-channel, two-fiber DWDM solution using 10g SFP+ optics is a great way to get 400G of capacity for links up to about 60km without the need for amplification or dispersion compensation. But what if you want higher data rates on the link? This is where things get a little tricky.

If we remove coherent optics from consideration due to the expense and complexity of deploying them, we see a pattern emerge. Here is a quick snapshot of the specifications of DWDM optics (non-coherent) we could consider:

Figure 6

That table attempts to remove a bunch of “noise” or complexity in determining if a simple point-to-point two-fiber solution will work. What we see when we review those specs is that as data rate increases, the unmodified reach and power budget both decrease.

Figure 7

Given these values, we can use the optical reach and power budget — along with the logical diagram shown in Figure 7 — to determine how long of a cross-connect we can achieve.

If we assume the 40-channel filter has a high-performance loss of 3db each, the patch panels have a loss of 0.5db each and the fiber loss is 0.25db per km (ITU-T G.657.A1 and G.652.D or better), then we can work backwards to see what the total span distance is per optic/data rate.

Figure 8

Reviewing the numbers in Figure 8, we can see that once you go beyond the 10G data rate, the unmodified reach becomes the limiting factor. For this illustration, we can expect to be able to establish some versatile, yet high-capacity, cross-connects.

We had already reviewed the capacity of a passive 40-channel system using 10Gbps optics and know that it can support 400Ghz worth of capacity. Using the same methodology, we can create links with a total line capacity of 1Tbps @ 25Gbps per channel up to ~15km, 1.6Tbps @ 40Gbps per channel up to ~8.8km, and a 4Tbps total capacity up to ~1.5km in fiber length. Knowing this can help reduce the total number cross-connects needed between any two points.

Also, worth noting: Not all channels need to be the same data rate. If the link distance is designed to work with 100Gbps links (or approximately 1.7km), that same link will be able to support 10G, 25G and 40G channels as well.

Summary

Earlier we mentioned we were “removing a lot of noise” — and then continued to make a great deal of assumptions to come up with these numbers. For instance, Forward Error Correction (FEC) is required and must be available on the host device for the links 25Gbps and higher. We made assumptions about fiber type, used calculated losses for the fiber spans, and assumed the total SFP+, SFP28, QSFP+, and QSFP28 ports were available at each end.

What this proved is that by combining passive filters and DWDM optics, we can increase the capacity as much as 40x per cross-connect pair. All this needs no power (except the switches), can be turned up very quickly, requires only 1RU of rack space (not counting the switches or patch panels), and adds zero latency.

As should be clear by now, this is not meant to be taken as gospel, and every effort should be made to know the optic specifications you are considering, the fiber type of the cross-connect, and have measured fiber loss and dispersion values before deploying.

When planned correctly, your CWDM plus DWDM can mean increased capacity without a big financial outlay. And your network can perform better as well.

A Comprehensive Understanding of SFP Optical Transceiver

SFP optical transceiver is still being used as an industry standard by worldwide manufacturers and providers today. It has been an industry workhorse for over 20 years in many networks such as PON, WDM, Fibre Channel, SONET, and other communications standards. This paper will give you a comprehensive understanding of SFP optical transceivers.

What is an SFP Optical Transceiver? 

A small form-factor pluggable(SFP) optical transceiver is a hot-pluggable interface used to transmit and receive data over fiber optic cable. It consists of FP or DBF laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. It satisfies class-I laser safety requirements and is compatible with the SFP multi-source agreement (MSA) and SFF-8472.

Types of SFP Optical Transceiver

Fiber Optic Cable Type

SFP optical transceiver can work over fiber optic cable and copper cable. Based on the types of fiber optic cable, SFP optical transceivers are divided into single-mode and multi-mode SFP optical transceivers. Single-mode SFP optical transceiver works with single-mode fiber. While multi-mode SFP optical transceiver works with multi-mode fiber.

Transmission Distance Range

Multi-mode SFP optical transceiver is used for shorter transmission distances up to 550m and 2km. Single-mode SFP optical transceiver is used for longer transmission distances up to 10~120km.

Transfer Rate

The trend towards higher speed and higher bandwidth is always unstoppable, from Fast Ethernet to Gigabit Ethernet, and then to 10Gb, 40Gb, 25Gb, and 100Gb Ethernet. Since the development of SFP, modernized advancements have been added to the mix. Namely, SFP+ for 10 Gigabit, SFP28 for 25 Gigabit Ethernet, QSFP for 40 Gigabit Ethernet, and QSFP28 for 100G Gigabit Ethernet are now available.

Application

3G-SDI video SFP optical transceivers are designed to meet the high standard video transmission needs in the high definition (HD) application.

PON SFP optical transceivers are used in the optical line terminal (OLT) at the central office and the optical network terminal/unit (ONT/ONU) at the subscriber’s premises.

CWDM and DWDM SFP optical transceivers are used by telecom systems in long-distance transmission, allowing them to transmit multiple signals simultaneously on a single fiber.

BIDI SFP optical transceiver transmits and receives data to interconnected network devices (like switches or routers) via a single optical fiber. It enables users to simplify their cabling system, increasing network capacity and reducing cost.

Fibre channel SFP optical transceiver is a high-speed network technology (commonly running at 1, 2, 4, 8, 16, 32, and 128 gigabits per second rates) used to connect computer data storage to servers in the SAN data center environment.

SONET/SDH SFP optical transceiver is compatible with the SONET/SDH and ATM standard, which covers the standard range of data rates extending from OC-3/STM-1 (155 Mbps) to OC-48/STM-16 (2.488Gbps) for multi-mode (MM), short-reach (SR), intermediate-reach (IR1), and long-reach (LR1/LR2) applications.

Applications

SFP optical transceiver is used in the switch-to-switch interface, router/Server interface, HD video, PON, WDM (CWDM, DWDM), data centers, telecommunications networks, etc.

Conclusion

An SFP is a small optical transceiver that plugs into an SFP port on a network switch or server. It has a high data rate, is small in size, and is easy to use and deploy.
