  • Application of 50G optical module in 5G
    Application of 50G optical module in 5G
    • December 15. 2020

    At present, 5G has started the commercialization process, but the complex bearer scheme leads to the increase of the corresponding optical module types. For 5G forward transmission, in terms of speed, AAU has introduced the eCPRI protocol standard, and the forward 25G rate has become the standard of various equipment manufacturers. Because of this, the rate standard of the carrier network will be ...

  • Five differences between CWDM and DWDM optical module
    Five differences between CWDM and DWDM optical module
    • December 17. 2020

    WDM is a technology to solve the shortage of optical fiber resources. Its main purpose is to increase the available bandwidth of optical fiber without laying more fibers. CWDM and DWDM are two kinds of WDM technology which are widely used in telecommunication. They are mainly used in WDM / demultiplexer. WDM / demultiplexer should be used together with WDM optical module. Next ETU-LINK will show y...
