Optical Fiber Transceiver Troubleshooting

Optical Transceiver Common Faults 1 Power light is off Power failure.

2Link light is off The fault may have the following conditions:

(a) Check if the optical fiber line is open circuited;

(b) Check whether the loss of the optical fiber line is too large and exceeds the receiving range of the equipment;

(c) Check that the optical fiber interface is connected correctly, the local TX is connected to the far RX, and the remote TX is connected to the local RX;

(d) Check that the fiber optic connector is properly inserted into the device interface,

Whether the jumper type matches the device interface,

Whether the device type matches the optical fiber and the transmission length of the device matches the distance.

3. Circuit Link light is off The fault may have the following conditions:

(a) Check if the network cable is open circuited;

(b) Check whether the connection types match: The devices such as network cards and routers use crossover cables, and switches and hubs use direct lines.

(c) Check whether the transmission rate of the equipment matches;

4.

The network packet loss is serious and the possible faults are as follows: (1) The transceiver port is not connected to the network device interface, or the duplex mode of the device interfaces at both ends does not match;

(2) There is a problem with the twisted pair and the RJ-45 head for detection;

(3) Fiber connection problems, whether the jumper is aligned with the device interface, and whether the pigtail is matched with the jumper and coupler type;
