  • 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...
