How does the optical time domain reflectometer use “backscattered” light to make
measurements?

A.
It uses pulses to locate and test for sheath faults, damaged conductors, loose connectors,
splices, bridge taps, split pairs, and other problems.

B.
It performs wiremapping to measure that all pins are correctly connected.

C.
It correlates the returned light pulses with a location in the fiber.

D.
It measures light-pulse width to measure that all pins are correctly connected.
