A single fiber optical transceiver, known as Bidi transceiver, allows bidirectional communication over a single optical fiber. This design uses two different wavelengths for transmitting and receiving signals. For example, one wavelength might handle transmission while another. BiDi transceiver, a compact optical transceiver with WDM (wavelength division multiplexing) technology and SFP multi-source protocol (MSA) compliance, allows fast data transmission using a single fiber optic for both sending and receiving signals, saving resources and cutting infrastructure costs. Bidirectional fiber delivers multiple practical benefits to 100G Ethernet deployments: Reduction in capital expenditure: You can re-use your existing LC multimode fiber (MMF) infrastructure instead of buying new cables. Reduced operational costs: BiDi allows for a straightforward 25G/40G/50G/100G. However, recently I have encountered several devices that utilize a single fiber while providing bidirectional communication.
