Maintenance Testing and Troubleshooting Techniques
Locating the break or problem
- OTDR,Optical Time Domain Reflectometer
- setup ….what index of refraction, what pulse width, what averaging time, what total display distance, is there a reference trace from previous recordings
- shooting the fiber and diagnosis … do I see a good launch, do I see the end, should I adjust the “setup” and shoot again, what problems are there
