2.6 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 100/1000Base SFP Fiber ports, which
require using the 100M or 1G mini-GBIC fiber transceivers to work properly. Advant -
ech provides completed transceiver models for different distance requirement.
The concept behind the LC port and cable is quite straight forward. Suppose that 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.
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).
2.6.1 Installing SFP Modules
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! This is a Class 1 Laser/LED product. To avoid causing serious damage
to your eyes, do not stare directly into the Laser Beam.
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.
