As we learned, a common SFP transceiver is generally with two ports, one is TX port to transmit the signal, and the other one is RX port to receive signals. BiDi SFP transceiver is only with one port which uses an integral WDM coupler to transmit and receive signals over a single strand fiber. SFP and BiDi SFP Connection Methods All SFP transceivers must be used by pairs. For common SFPs...
