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).

Redundant Power Inputs

For PTC-101-LV series, both power inputs can be connected simultaneously to

live DC power sources. If one power source fails, the other live source acts as a

backup, and automatically supplies all of Moxa Industrial Media Converter’s

power needs.
