Conventional fiber optic transmission is single-fiber unidirectional, to achieve bi-directional communication requires two optical fibers, compared to the BiDi technology requires only one optical fiber can be, that is, the existing optical fiber transmission capacity doubled . Conventional fiber optic transmission is single-fiber unidirectional, to achieve bi-directional communication requires two optical fibers, compared to the BiDi technology requires only one optical fiber can be, that is, the existing optical fiber transmission capacity doubled . The WDM system supports two transmission modes: single-fiber unidirectional and single-fiber bidirectional. In this mode, the WDM system transmits multi-wavelength optical signals in receive and transmit directions through separate fibers. Simple design and low requirements. Easy fault isolation. BiDi optical modules can do this by utilizing full-duplex communication over a single fiber strand via two wavelengths. 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. A bidirectional SFP (BiDi SFP) provides an efficient solution by enabling data transmission and reception over a single strand of optical fiber. By using Wavelength Division Multiplexing (WDM), BiDi SFP modules transmit and receive data on two different wavelengths, cutting. At one side a 1000BASE-BX10-U (Tx1310nm/Rx1490nm) BiDi SFP transceiver transmit a 1310nm wavelength optical signal and receive a 1490nm optical signal while the opposite side of the single-fiber bidirectional link 1000BASE-BX10-D (Tx1490nm/Rx1310nm) BiDi SFP transmit a wavelength of 1490nm and. Single-fiber bidirectional, also known as BiDi (Bidirectional), refers to an optical fiber can simultaneously send and receive optical signals in two directions.
