Common Faults and Solutions
1. Communication interruption
Cause: It may be due to poor optical fiber connection, optical fiber damage, incorrect communication parameter settings of the module or module failure.
Solution: Check whether the optical fiber connection is firm and whether there are situations such as bending and damage. If there are problems, reconnect or replace the optical fiber; confirm whether the communication parameter settings are correct, such as the baud rate, data bits, stop bits, etc.; if it is a module failure, try to restart the module. If the problem still cannot be solved, contact professional maintenance personnel for inspection or module replacement.
2. Signal transmission error
Cause: It may be due to electromagnetic interference, excessive optical fiber attenuation, unstable electrical performance of the module, etc.
Solution: Conduct electromagnetic shielding for the optical fiber and the module to reduce electromagnetic interference; check the attenuation of the optical fiber. If it exceeds the specified value, find the cause and deal with it, such as replacing the optical fiber or optimizing the laying path of the optical fiber; check whether the power supply of the module is stable and whether the module is overheated. If there are problems, take corresponding measures to solve them, such as replacing the power supply or improving the heat dissipation conditions.
3. Module failure
Cause: It may be caused by component damage, overheating, overvoltage, etc.
Solution: Check whether there are signs such as charring and deformation on the appearance of the module. If so, replace the module; use professional detection equipment to detect the module, find the faulty component and replace it; check whether the working environment temperature and voltage of the module are within the specified range. If it exceeds the range, take measures to adjust it to avoid the module being damaged due to overheating or overvoltage.
