Connecting and Terminating

SC Connector

Each fiber optic link consists of two strands of fiber optic cabling: the transmit
(TX) and the receive (RX). The transmit strand from a module port connects to the
receive port of a fiber optic Ethernet device at the other end of the segment. The
receive strand of the applicable port on the module connects to the transmit port
of the fiber optic Ethernet device. As duplex SC Connectors are designed to only
be inserted into SC ports in one fashion, there is little chance of a mis-connection
due to improper crossover occurring.
Cabletron Systems recommends labeling fiber optic cables to indicate receive and
transmit ends. Many cables are prelabeled, providing matching labels or tapes at
both ends of each strand of cable.
