BiDi SFP transceiver is only with one port which uses an integral WDM coupler to transmit and receive signals over a single strand fiber
a common SFP transceiver is generally with two ports, one is TX port which is used to transmit the signal, and the other one is RX port which is used to receive signals

Bi-Directional BX

BX or Bi-Directional transceivers can transmit 1000Mbps of data up to 10 km over a single strand of single-mode simplex fiber. Longer distances up to 80 km can be achieved through custom builds.

Digital Optical Monitoring (DOM)

DOM, short for Digital optical monitoring, is familiar with the DDM function. It is also a feature which allows you to monitor many parameters of the transceiver module in real-time. DOM allows you to monitor the TX (transmit) and RX (receive) of the module, as well as input/output power, temperature, and voltage. Network administrators can then check and ensure that the module is functioning correctly
