meter,don't use the medical alcohol.
4.5 Please use the 24dBm、25dBm、26dBm PLC splitter for the output to prevent pigtail
hurt by the high power amplifier.
4.6 Don't test EDFA with pigtail again and again, it will hurt the fiber connector and make
the factual power become smaller.
4.7 Light amplifier have a small influence on CTB and CSC,mainly influence C/N.After
increasing the value of input power,then C/N will be higher,if reduce the value of input
power,C/N will be lower.So input power suggest to reach 4dBm,also the 1.5dBm of
optical switch loss figure in.
5. Common Fault
5.1 Display
Power supply light STATUS: green
LED light Laser: red
VFD display: NO LASER INPUT
Reason: N0 1550nm optical input
Solution: Input 1550nm optical signal
5.2 In fiber amplifier,the panel display is synchronized with the output.And if it displays the
right optical power, but the optical power is not enough by test meter,as following
possibilities:
5.2.1Don't use domestic optical meter to test EDFA,because the domestic optical meter
can't test fiber amplifier with high power.So should use imported optical meter.
5.2.2 The output flange is damaged.
5.2.3 Plug the pigtail in the machine working time, let the pigtail be damaged,cause the
output power to decease.you can splice the output connector.
5.2.4 Use a bad quality pigtail with a long fiber core that scrape the fiber amplifier
connector, is normal in the first time testing ,and optical power is smaller in the second
time,splicing the output connector is right.
5.2.5 The wavelength of the optical is not right and cause output power to decease,so the
