A Brief Introduction of Cisco BiDi SFP Transceiver

In the early stage of optical fiber communication, one optical fiber can only transmit signals of one wavelength. This is known as conventional two-fiber Bi-Directional communication – at least two fibers are needed to accomplish the full-duplex communication with TX and RX optical signals. With the development of WDM technology, transmitting and receiving of optical signals on separate wavelength can…
