100BaseFX or 1000BaseSFP Fiber Port

The Gigabit Ethernet ports on the EDS-600 series are SFP slots, which require

100BaseFX SFP or Gigabit 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).
