100BaseFx Ethernet Port Connection

The concept behind the SC port and cable is quite straightforward. Suppose you are

connecting devices I and II. Contrary to electrical signals, optical signals do not require a

circuit in order to transmit data. Consequently, one of the optical lines is used to transmit

data from device I to device II, and the other optical line is used transmit data from device

II to device I, for full-duplex transmission.

All you need to remember is to connect the Tx (transmit) port of device I to the Rx (receive)

port of device II, and the Rx (receive) port of device I to the Tx (transmit) port of device II.

If you are making your own cable, we suggest labeling the two sides of the same line with

the same letter (A-to-A and B-to-B, as shown below, or A1-to-A2 and B1-to-B2).
