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