We experimentally demonstrate 100 Gb/s bidirectional transmission over 40 km using a multi-wavelength bidirectional optical sub-assembly (BOSA) based on a single bidirectional multi-wavelength Mux/Demux. The Mux/Demux consists of an optical zig-zag glass block and thin film. A bidirectional SFP (BiDi SFP) provides an efficient solution by enabling data transmission and reception over a single strand of optical fiber. This physical-layer design instantly doubles existing cable plant capacity without requiring expensive new. 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. In the world of transceivers, BiDi stands for Bi-Directional. In terms of SFPs, BiDi transceivers transmit at one wavelength and receive at another. BiDi SFPs connect to a fiber cable using only one. A 1G BiDi transceiver solves these challenges through single-fiber bidirectional transmission, giving networks a more economical and efficient upgrade path.
