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 17 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 fiber
(<20km) for connection. If such a short fiber is used, the module will be burned.
