100/1000BaseSFP (mini-GBIC) Fiber Port
One of the Gigabit Ethernet ports on the EDS-G205-1GTXSFP is an SFP
slot, which requires 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 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).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the laser beam.
Redundant Power Inputs
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 the switch’s power needs.
