Chapter 14 Fiber Optic Testing

Question 1

What is the most important measurements parameter when testing FIBER OPTIC’s?

What is the second?

What are the Third?

Answer 1

1. Optical Power:
   source power, receiver power, and loss or attenuation
2. Backscatter (OTDR) measurements are the next most important,
3. Bandwidth, Wavelength, and dispersion

Question 2

What is fiber tested at?
Multimode

Singlemode

Answer 2

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
