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.
