How to connect TX and RX fiber optic switches

A fiber-optic link can function only if Tx on one end is connected to Rx on the other, and vice versa; this is accomplished by creating a fiber polarity flip that swaps Tx for Rx at some point in the link. For duplex transmission, this is relatively straightfo...
