Installing and Removing SFP Modules
Up to two fiber optic ports are available (dependent on model) for use in the switch. Refer to
the technical specifications for details.
The Gigabit Ethernet ports on the switch are 100Base SFP Fiber ports, which require using
the 100M or 1G mini-GBIC fiber transceivers to work properly. Advantech provides completed
transceiver models for different distance requirement.
The concept behind the LC port and cable is quite straight forward. Suppose that you are con-
necting 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.
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).
To connect the fiber transceiver and LC cable, use the following guidelines:
1.
Remove the dust plug from the fiber optic slot chosen for the SFP transceiver.

Note!
Do not remove the dust plug from the SFP slot if you are not installing
the transceiver at this time. The dust plug protects hardware from dust
contamination.
