Installation
Before installation
1. Please be sure there is no visible damage outside the machine.
2. Please check the spare parts is complete or not, if not complete, please contact the seller.
Installation
1. Please keep at least 4.5cm (1.75inches) space for cooling if the machine is installed with
other machines.

2. Please check the power supply socket and the grounding of the power supply, the
grounding impedance should be ≤4Ω, 220V power supply should be with three cables and
the grounding cable should be in the middle, Untted grounding will damage the device or
influence the signal quality.
3. Please make sure the power supply switch is off in the rear panel
4. Please conrm the ber port is clean before connection the ber.

NOTES
1. The main component of the amplier laser is sensitive to the static electricity, so please keep the
amplier away from the static electricity. Furthermore, please keep it away from caustic things. Please
keep the amplier 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 repeatedly.
SOLUTION TO SOME ORDINARY PROBLEM
1. Power supply light STATUS: green
LED light LASER: red
VFD display: NO LASER INPUT
Reason: N0 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 ber connector and make the factual
power become smaller.
