V. Notes
1. The main component of the amplifier laser is sensitive to the static electricity,
so please keep the amplifier away from the static electricity. Furthermore,
please keep it away from caustic things. Please keep the amplifier in
temperature between -25℃and 65℃.
2. Please make sure the power is earthed.
3. Please don’t now attempt to look into the optical connectors when power
applied, eye damage may result.
4. Please don’t block up the heating dispersion hole and keep the machine
aired.
5. Please don’t unfold the machine or remove any parts of the machine.
6．Please don’t insert the patch cord when the power is on
7. Please don’t test the EDFA more than 5 times.
VI. Solution to some ordinary problem
1. Power supply light STATUS: green
LED light LASER: red
VFD display: NO LASER INPUT
Reason: No 1550nm optical input
Solution: Input 1550nm optical signal
2. In LED n it displays the right optical power, but not enough by test meter
Reason: 1. the optical meter is not very correct
2. the input optical power is out of the requested value( -3～10dB)
3. too big loss in the test pigtail
4. There is dust in the connectors
Solution:
Use absolute alcohol to wash the all the connects and the test point of

optical meter
Note:
1. Don’t use Chinese optical meter to test EDFA.
2. Don’t test EDFA with pigtail again and again, it will hurt the
fiber connector and make the factual power become smaller.
