100/1000BaseSFP (mini-GBIC) Fiber Port
The Fiber ports on the EDS-G308 series are SFP type slots, which require
100M or 1G mini-GBIC fiber transceivers to work properly. Moxa provides
complete transceiver models for various distance requirements.
The concept behind the LC port and cable is quite straightforward.
Suppose you are connecting devices I and II. Unlike 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 to transmit data from
device II to device I, for full-duplex transmission.
Remember 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 make 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).
