  • Introduction and application of 200G QSFP-DD SR8 optical module
    Introduction and application of 200G QSFP-DD SR8 optical module
    • January 09. 2021

    As the internal traffic of the Internet giant's data center increases nearly 100% every year, many giants will seek 200G optical module to solve the growing demand for data transmission. There are mainly two types of 200G optical modules: QSFP-DD and QSFP56. Among them, QSFP-DD refers to four channel small pluggable double density package, which is defined by QSFP-DD MSA group, which is twice the ...

    Introduction and application of 100G QSFP28 CWDM4 optical module
    • January 19. 2021

    Nowadays, with the increasing demand of network throughput and bandwidth, the demand of 100G high-speed optical module is also growing. IEEE has developed two optical module standards for 100G network: 100G SR4 QSFP28 and 100G LR4 QSFP28. But in practical application, because the transmission distance of the above optical modules can not fully cover the transmission distance requirements of t...

    Introduction and application of 25G SFP28 CWDM optical module
    • February 26. 2021

    2020 is the first year that 5G will be commercialized. At present, 25G optical modules have also been used in the construction of 5G signal base stations. Among them, 25G CWDM optical modules have a high market prospect in 5G fronthaul. Compared with other 25G optical modules, 25G CWDM optical module can save more fiber resources, thus effectively saving the total cost of operators. As early as 20...

    25G Ethernet may become the new trend of network in the future
    • March 20. 2021

    With the increasing demand of data center for bandwidth, the network rate is developing towards a higher rate, and there is bound to be the need for network upgrading. There are two upgrade paths for the network from 10G to 100G, namely 10G-25G-100G and 10G-40G-100G. End users seem to prefer 25G. Why? ETU-LINK will tell you.   All this can be said from the rise of 25 Ethernet. Data center TOR...

    400G optical module QSFP-DD package type introduction
    • March 30. 2021

    Since 2019, 400G has become a hot topic in the optical communications industry. Several leading optical module manufacturers in the world have launched their own 400G optical modules and most of them have adopted QSFP-DD packages. As early as March 21, 2016, the QSFP-DD MSA team began to plan to develop the QSFP-DD high-speed interface, and experienced the resolution of a series of issues suc...

    A router is a hardware device that connects two or more networks. It acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. Routers can be divided into backbone routers (core routers), enterprise-level routers, and access-level routers.   Generally, backbone routers have multiple optical ...

  • What is the FEC function of 100G optical module?
    What is the FEC function of 100G optical module?
    • April 10. 2021

    Two important development trends of optical modules are to increase the transmission rate and extend the transmission distance. However, as the transmission rate increases, the signal transmission distance will be limited by many factors, such as chromatic dispersion, nonlinear effects, and polarization mode dispersion. These factors will limit the increase in transmission rate and trans...
