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. 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
connecting devices I and II; contrary to electrical signals, optical signals do not require a cir-
cuit 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, or A1-to-A2 and B1-to-B2).
