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 same speed, wavelength, and optical mode. Multi-mode optical modules are applicable to short-distance transmission, while single-mode optical modules are applicable to long-distance transmission. This means you can find combinations such as single-mode single-fiber modules or multi-mode dual-fiber modules: Most single-fiber modules are single-mode due to the complexity and cost of wavelength multiplexing in. Other BiDi pairs exist (e. The key is opposite directions use opposite wavelengths, so A must face B—AA or BB will not work.
