Publication Date:  2012-07-25 Views:  29 Downloads:  0
Issue Description
Customers may ask why we need to de-multiplexe OSC channel before OA in OLA.
Alarm Information
NULL
Handling Process
NULL
Root Cause
There are two reasons for this question

1. The wavelength of OSC is 1510nm. But EDFA just used in the 1550nm window, OSC can not be amplifed by EDFA.
2.According to the ITU-T recommendations ,  OSC should work stable when OA is faulty , so OSC mustn't pass through OA.



Suggestions
After all , OSC can not be amplifed by EDFA , and it mustn't be amplifed by EDFA.
