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.

 Primus IT offers high-quality modules to meet the demand of datacom and telecom networks and toenable the next generation of optical transceivers.

  Telecom network operation

The downstream optical module is mainly used in the three major scenarios of telecommunications bearer network, access network, data center and Ethernet.

 The telecommunications bearer network and access network belong to the telecommunications operation market. Among them, wavelength division multiplexing (xWDM) optical modules are mainly used for medium and long-distance telecommunications bearer networks, and optical interconnects are mainly used for backbone networks and long-distance core networks. Capacity transmission; and the access network market is the "last mile" from operators to users, including fiber-to-the-home passive optical networks (FTTH PON, PON optical modules currently have a maximum transmission rate of 10Gbs), wireless fronthaul (5G optical modules, The current maximum transmission rate is 25Gbs) and other application scenarios.

  What is telecom network infrastructure

The telecommunication network is composed of three parts: core network, access network (AN) and customer premises network (CPN).

 The core network and access network belong to the public telecommunication network, CPN is a user-owned communication network, and traditional CPN is a single user.

 One side of the access network is the core network, which is mainly composed of various business networks, and the other side is the user. The access network serves as a link between the previous and the next, and provides the services of the core network to users through the access network. The access network is a transparent transmission system that does not provide services by itself. User terminals cooperate with the core network to provide various services.

  Fundamentals of telecommunications and networking for it

A telecommunication network is a system that organically connects various telecommunication points and telecommunication circuits. It is composed of three parts: terminal equipment, switching equipment and transmission equipment. The first two constitute telecommunication points; transmission equipment constitutes telecommunication circuits.

 1. According to different business types and communication methods, it can be divided into telephone communication network, telegraph communication network, data communication network, user telegraph communication network and fax communication network.

 2. According to different communication ranges, it can be divided into international telecommunication networks, domestic telecommunication networks, long-distance telecommunication networks, intra-city telecommunication networks and rural telecommunication networks.

 3. In terms of the nature of use, there are private telecommunication networks and public telecommunication networks. The private telecommunications network is only available to certain professional users, such as the private telecommunications network of railway, military and other departments; the public telecommunications network can be used by ordinary citizens.

 4. From the way of signal transmission, it can be divided into analog communication network and digital communication network.

  The relationship between data communication and telecommunication

Data communication is a new communication method produced by the combination of communication technology and computer technology. To transmit information between the two places, there must be a transmission channel. According to the different transmission media, there are wired data communications and wireless data communications. But they all connect the data terminal and the computer through the transmission channel, so that the data terminals in different locations can share software, hardware, and information resources.

 Telecommunications is now the main form of communication, and its main task is to use wired electricity, radio, light, etc. to transmit information such as symbols, text, images, and language. Since telecommunications use electric waves to transmit information, terrain obstacles, solar activity, etc., sometimes affect the quality of communication.

  FAQs of Datacom/Telecom Network

What is datacom network?

The data network is a communication network used to transmit data services. It uses data switches (packet switching, frame relay switching, ATM switching, advanced routers, IP switches, etc.) as transfer points to form a world, national and regional network. It is a product of the comprehensive application of computer hardware and software technology based on modern transmission technology.

 What is telecom network?

The telecommunications network is a comprehensive system composed of transmission, switching, terminal facilities and signalling processes, protocols, and corresponding operation support systems. It can be conceptually divided into equipment (physical) networks and business networks

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.
