What is the reason that the output power of the fiber amplifier is reduced or insufficient?

If the panel display is the same as the actual output, then consider the following reasons:

1. The quality of the pigtail used by the user is too poor, and the core is too long. After inserting the pigtail, scratch the output connector of the optical amplifier. This phenomenon is good for the first test, and the optical power drops when the second test is inserted again. To solve this problem, just re-splice the output connector of the optical amplifier;

2. Optical input power too low;

3. Wavelength deviation;

4. Optical power meter is not accurate;
