There are many types of light recovery, but the method of fault judgment is basically the same. The faults that will occur in the summary of the optical transceiver are as follows:

1. Power lights are not on

  electricity failure

2. The link light does not light up the fault may be as follows:

(A) Check whether the optical fiber line is disconnected

(B) Check whether the optical fiber line is too much, exceeding the device receiving range

(C) Check whether the optical fiber interface is connected correctly. The local TX is connected to the RX in the distance, and the distance TX in the distance is connected to the local RX.

(D) Check whether the fiber connector is intact into the device interface, whether the type of jumping line matches the device interface, whether the equipment type matches the fiber, and whether the equipment transmission length is matched with the distance.

3. Circuit LINK light does not light up and faults may be as follows:

(A) Check whether the network cable is disconnected

(B) Check whether the connection type is matched: cross -line, switches, hubs and other equipment such as network cards and routers and other equipment uses direct lines.

(C) Check whether the transmission rate of the device matches

4. The network package loss may be seriously faulty as follows:
