Single fiber modules (BiDi) use one fiber for both transmitting and receiving data. This saves space and money. Dual fiber modules use two fibers. They are easier to set up and give steady communication. In DWDM implementations, each direction of communication occupies a dedicated fiber, improving the stability of the transmission. This configuration is widely adopted in traditional telecom. Single-fiber WDM (also known as bidirectional or BiDi WDM) uses one physical optical fiber strand to transmit and receive signals simultaneously—often employing different wavelengths for upstream and downstream.
