Must optical fiber jumper be used in pairs?

The reason of using fiber jumper wires in couples is related to its connecting equipment. In fact, fiber jumper wire is a kind of communication fiber nothing but the distance which connecting two fibers communication equipment is much short, so it is called optical fiber jumper wire.


The general optical transmission is one receiving and the other transmitting. According to the facility request (such as video optical transceiver), facility to facility and multi-mode, then we use jumper wires in pairs. It will transmit by single fiber if it is single-mode, there is no need to use jumper wires in pairs. However, for devices are usually used in pairs, optical fiber jumper wires are bought in pairs.
