Single-mode fiber supports full-duplex communication over a single strand by using different wavelengths for transmitting and receiving data. This is typically achieved through wavelength division multiplexing (WDM), where one wavelength carries the upstream signal and another wavelength carries the downstream signal. WDM transceivers separate these wavelengths, allowing simultaneous transmission and reception without interference .
BiDi SFP modules are a common implementation of this technology. They use two different wavelengths on the same fiber strand, with each end of the link using complementary wavelengths. This allows a single fiber to handle both directions of data flow, reducing fiber usage and infrastructure costs. BiDi modules are available in multiple speed classes, including 1G, 10G, and even 40G, making them suitable for both legacy and high-bandwidth networks .
