Q
What is the most important measurements parameter when testing FIBER OPTIC’s?
What is the second?
What are the Third?
A
- Optical Power:
source power, receiver power, and loss or attenuation - Backscatter (OTDR) measurements are the next most important,
- Bandwidth, Wavelength, and dispersion

Q
What is fiber tested at?
Multimode
Singlemode
A
Multimode fiber is tested at 850nm to 1300nm
Singlemode is tested at 1310n unless very long cables runs are involved. Which would test at 1550nm this is because it will give you info on the stress of the cable
