Verification of repeater optical cables
Basically, there are three methods commonly performed for optical fiber testing: visible light source, power meter and light source (one jumper method), and optical time domain reflectometer (OTDR). For some conditions, the output spectrum of an EDFA/OA would be distorted this has to be analyzed for various. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. After fiber optic cables are installed, spliced and terminated, they must be tested. All of these features can significantly improve your network performance, reliability, and manageability in the long run.
