Use one fiber strand for both directions simultaneously. Achieve this with WDM (wavelength division multiplexing): each end transmits and receives on different wavelengths over the same strand. You must deploy A/B ends a...

Use single-fiber bidirectional optical modules in pairs - GDR Telecom Site Energy Systems [PDF]
Short answer: Usually yes, you use them in pairs, but the “pair” can be a media converter on one end and a fiber switch (or SFP in a switch) on the other, as long as both sides speak the
Paired BiDi modules multiplex and demultiplex the two wavelengths onto a single fiber, allowing for simultaneous bidirectional data flow effectively. This practical design reduces cabling
Applying BIDI (bidirectional) modules to bidirectional transmission services can realize information transfer and reception simultaneously over a single optical fiber.
Unlike traditional optical modules that use separate optical fibers to transmit and receive data, BiDi modules complete this bidirectional data transmission on a single optical fiber, optimizing
Different center wavelengths are used for the two directions. This mode saves half of the fiber resources compared to the single-fiber unidirectional transmission mode, but it has a more complex design and
Learn how BiDi transceivers enable bidirectional data over a single fiber: how they work, common wavelength pairs, advantages, and deployment tips.
WDM BiDi (Wavelength Division Multiplexing Bidirectional) SFP+ transceivers are specialized optical modules that transmit and receive data simultaneously over a single fiber by using
Paired BiDi modules multiplex and demultiplex the two wavelengths onto a single fiber, allowing for simultaneous bidirectional data flow effectively.
Traditional optical modules use separate fibers for transmitting and receiving data. In contrast, BiDi SFP+ must be used in pairs and it can utilize a single fiber for both functions.
Learn how to choose the right bidirectional SFP for single-fiber links. Compare wavelengths, distances, and compatibility to optimize your optical network.
BiDi optical modules must be used in pairs to achieve bidirectional data transmission.
