Gigabit SFP module is equipped with LC connector, and each port consists
of a TX (transmit) port and an RX (receive) port, as shown in Figure 12.
To enable data transmission between Switch A and Switch B, connect the
TX (transmit) port of Switch A to the RX (receive) port of Switch B, and the
RX (receive) port of Switch A to the TX (transmit) port of Switch B, as
shown in Figure 12.

How to Determine the RX Port and TX Port of Gigabit SFP Module
1. Insert the two connectors in one end of optical fiber into gigabit SFP
module, and those in the other end of the optical fiber into the SFP
module of another switch.
2. Check the corresponding port Link/ACT indicator in the front panel:
If the indicator blinks, the link is connected.
If the indicator 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 in the one end of the optical fiber.
How to Connect the Gigabit SFP Optical Module
Insert the gigabit SFP module into the 1000Base-X SFP slot in the
switch, and then plug the optical fiber into the TX port and RX port of
the SFP module, as shown in Figure 13.
