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.
