Do multimode optical modules always need to be in pairs
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. This document explains the optical connectivity involved in 40G optical QSFP for short reach (40GBASE-SR4), on multimode fibres. The standard specifies MPO12 (or MTP12) as connector to the SR4 QSFP, which employs traditionally 12 fibres, but 40G only need 8 (4 pairs) to carry the 4 parallels. Single-mode optical modules are best for long distances and fast speeds. Multi-mode modules are good for short distances. This configuration allows data to be transmitted in both directions simultaneously, which is essential for most modern communication systems. Single-mode Fibers: These. Unlike general optical modules with two ports (Tx and Rx), BiDi optical modules have only one optical port and use wavelength division multiplexing (WDM) technology to transmit and receive optical signals of different center wavelengths over the same fiber.
