    The difference between single and dual fiber optical transceiver
    • December 30. 2019

    The are single and dual fiber optical transceiver. How do we choose, and what are their differences and advantages? Let’s learn about this! Single fiber module also called WDM module. It uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. BIDI module only has 1 port, wave filtering through the filter of module, and finished the transmitting of 131...

    What are the differences between the Gigabit BiDi and 10Gigabit BiDi module?
    • March 06. 2017

    BIDI SFP is a bidirectional optical module, also called WDM module. It uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. BIDI module only has 1 port, wave filtering through the filter of module, and finished the transmitting of 1310nm optical signal and receiving of 1550nm optical signal, or opposite. Therefore the module must be used in pairs. ...
