The Maintenance of Wavelength Division Multiplexers

The Maintenance of Wavelength Division Multiplexers

Maintenance items for long-term reliable operation of WDM:

1. Keep the ventilation holes of the equipment unobstructed.

2. Do not place the wavelength division multiplexer in a closed space, as this will prevent the air from circulating and cause the temperature of the chassis to be too high.

3. Do not place the power supply directly on top of the cell.

4. Keep the indoor environment dry.

Ways to troubleshoot WDM:

If the system is connected, but not streaming:

1. Use a short fiber jumper to connect the unit of the wavelength division multiplexer for inspection.

2. Check whether the fiber optic connector and fiber jumper are in good condition

3. Make sure that the wavelength of the wavelength division multiplexer is only transmitted once.

4. Check whether the optical module is inserted into the specified port of the wavelength division multiplexer.
