1. The optical power meter is not accurate, the domestic optical power meter can only test the equipment with small optical power output, and cannot test the EDFA with high power output, and the optical power meter of the optical amplifier must be imported originally, and the inaccurate instrument can not be used as a standard.
2. The flange of the output port is damaged, which is less likely.
3. The user improperly uses the pigtail, plugs and unplugs the pigtail when the machine is working, burns the pigtail head output by the optical amplifier, and forms a decrease in the output power of the optical amplifier.
4. The quality of the pigtail used by the user is too poor, the fiber core is too long, and the output connector of the optical amplifier is scratched after inserting the pigtail, this phenomenon is good for the first test, and the optical power decreases when the second time is inserted and tested again, and the output connector of the optical amplifier is only needed to be welded from scratch to deal with this problem.
5. The wavelength of the light source is wrong, if the wavelength of the 1550nm optical transmitter is incorrect, the output optical power of the optical amplifier will be insufficient, and the panel will be small.
6. The optical power of the input optical amplifier is small, and if it is lower than the standard value, the optical power may become smaller, and the panel display will also become smaller.

The working principle and purpose of Omron relays
How it works
Add a certain voltage at both ends of the coil, a certain current will flow through the coil, thus producing an electromagnetic effect, and the armature will overcome the tensile force of the return spring under the action of electromagnetic force attraction and attract to the core, thereby driving the dynamic contact and static contact (normally open contact) of the armature ...
