QSFP Cable and Connectors Assemblies

A quad (4-channel) Small Form-factor Pluggable Optics Transceiver is also known as a QSFP cable. For applications requiring 40 Gigabit Ethernet (40GbE) data transfers, it is a small, hot-pluggable fiber optical transceiver. They are often used for the implementation of 40G Ethernet, Infiniband, and other communications protocols in data centers.

It connects a fiber optic or copper cable to network equipment, such as a switch, router, media converter, or similar device.

In addition to copper cable media, QSFP+ optic transceivers are made to support Serial Attached SCSI, 40G Ethernet, 20G/40G Infiniband, and other fiber optic communication standards. In comparison to SFP+ optic modules, the QSFP28 cable significantly increases port density by 4x.

Optical transceivers are compact, strong devices that add fiber ports to switches or other networking equipment by connecting them to copper or fiber optic cables. Data is transmitted using optical fiber in conjunction with fiber optics in the form of light pulses that travel at very high speeds and can cover very long distances. The transceiver, which is a laser with a certain wavelength that transforms electrical signals into optical signals, is a crucial part of the fiber optic network. The data is then converted into a signal with a specific wavelength by the transceiver and sent over the optical fiber. Wideband signals are those that are 850 nm, 1310 nm, and 1550 nm in wavelength. Narrow bands are the term for CWDM or DWDM signals. Each channel is unable to interact with the others due to the special property of light.

This indicates that a network can handle the transmission of both wideband and narrowband signals. Direct attach copper (DAC), active optical cables (AOC), optical modules, and active copper cables are all types of QSFP interconnects (ACC). The least costly choice is DACs. They offer a connection that depends on host signal processing. The maximum length that can be achieved depends on the cable assembly's insertion loss, which is determined by its length and cable gauge and is guided by the IEEE specifications (see below) (AWG). The AWG of a wire has an inverse relationship with its size. AWG and wire diameter for QSFP cable assemblies are plotted in the table below.

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.
