* Question
| What are the common faults and solutions for fiber optic transceivers? |
* Answer
| 1.Fault phenomenon: the transceiver indicator light is not bright: Solution: Use the multimeter DC voltage file to measure the output of the AC/DC power transformer to see if the voltage is normal. If there is no output voltage, use the multimeter’s resistance file to measure whether the transformer primary is open, such as open circuit.Replace the power transformer.If there is red light, observe whether the emitting end of the fiber transceiver has red light, and how strong or weak.If there is no light or weak, replace the transceiver.3.Fault phenomenon: RX lamp and LINK lamp on UTP side are not lit: Solution: This fault phenomenon is a problem with the output.Use a line gauge to measure the twisted pair of the switch..Symptom: The indicator light is normal, the network speed is slow: Solution: Use the laptop to access the UTP end of the fiber transceiver, enter Windows98, click “Start” * “Run”, enter the “PingXXX-T” command (XXX isThe home page’s IP address), you can find a breakpoint.Replace the fiber optic transceiver. |
