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. ...
