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 19 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 one end of the fibers.
Caution:
The device uses laser to transmit signals in fibers. The laser meets the requirements of level 1
laser products. Routine operation is not harmful to your eyes, but do not look directly at the
fiber port when the device is powered on.
If the defined transmission distance of an SFP module is longer than 60km, do not use a short
