100BaseFx Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward.
Suppose you are connecting devices I and II. As opposed 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 by the following illustration, or A1-to-A2
and B1-to-B2).
