Gigabit SFP Optical Module
Figure 9 Gigabit SFP Optical Module
An SFP optical module is equipped with LC connector, and each port consists of a TX (transmit)
port and an RX (receive) port. To enable communication between Device A and Device B, connect
the TX port of Device A to the RX port of Device B, and the RX port of Device A to the TX port of
Device B, as shown in the following figure.

How to Connect the SFP Optical Module
Insert the SFP optical module into the SFP slot in the switch, and then insert the fibers into the TX
port and RX port of the SFP module.
Figure 11 Connecting the SFP Optical Module
Identify the RX port and TX port of an SFP optical module:
1. Insert the two connectors in one end of two fibers into the SFP module, and those in the other
end into the peer module.
2. View the corresponding connection status LED:
If the LED is on, the connection is correct. If the LED is off, the link is not connected. This may be
caused by incorrect connection of the TX and RX ports. In this case, swop the two connectors at
