Ⅳ. high power optical amplifier -
1. Please avoid eyes directly to output.
2. Please turn off the power first then plug in or out the patch cord
3. EDFA has very small influence on CSO and CTB, but has big influence in C/N.
The input optical power influence the C/N. High optical input gets higher C/N. Please see the
following data. The minimum optical input should be 4dBm.

Ⅴ.high power optical amplifier Normal - Trouble Solution
The display in screen of the EDFA shows the correct output of the pump laser, if the output
is lower than showed, please check as the following steps.
1. Check the optical meter. Because of the high out of EDFA, please don’t use Chinese
optical meter to test the EDFA, the advised one is EXFO.
2. The output adaptor burnt.
3. The operator plug in and out the patch cord when the power on, this will burnt the
output pigtail connector and make the output lower. The solution is to splice a new
the pigtail connector.
4. Some operators use the bad quality patch cord and its fiber core is too long, after
connected, it will hurts the pigtail of pump laser output. In this condition, in the
first test, the output is correct, but in the second time, the output become lower.
The solution is also to splice a new pigtail connector.
5. The wavelength of the input deviates far from 1550nm, it will make both the
outputport and screen show lower.
6. Too low input will make both the output and screen show lower.
Ⅵ.high power optical amplifier - Precautions:
1. Before installation or operation of unit, please carefully go through the user’s manual.
2. OLAH Series EDFA should be serviced only by qualified personnel.
3. Before proceeding with installation and/or operation of transmitter, please assure that transmitter is well earthed.
4. OLAH series EDFA are Class III laser products. Use of controls, adjustments, and procedures other than those
specified herein may result in hazardous laser radiation exposure.
