By applying optical multiplexing techniques, the bandwidth of fiber optics can be utilized more efficiently. There are three primary optical multiplexing techniques. The most basic technique, space-division multiplexing (SDM), is a brute-force approach that simply uses separate optical fibers for each channel. Of course, this approach starts to become unwieldy as the number of channels and connections increases in a fully connected network.
