Bidirectional (BiDi) optical modules utilize wavelength division multiplexing/wavelength selective coupling (WDM) technology to provide simultaneous transmit and receive capability over a single fiber strand. By reading this blog, you will understand how SFP BiDi technology allows you to save fiber, reduce costs, and simplify installation while enabling your network to increase. For bi-directional transmission technology, “bi-directional” is meant in sense of using optical fiber in two directions, similar to the use of single railway track in two directions. In practical network deployments, this makes BiDi SFP modules a highly effective solution for. The WDM system supports two transmission modes: single-fiber unidirectional and single-fiber bidirectional. Simple design and low requirements.
