What is OTDR Testing?

OTDR locates and measures points in a fiber optic link to test fiber links' performance and identify problems.

OTDR Testing Procedure

How do you test OTDR?  OTDR testing may use a launch cable, sometimes with a receive cable. Users must first set up the OTDR by selecting measurement parameters such as test range, test pulse width, test pulse width wavelength, and the number of trace averages. Then the user attaches the launch reference cable to the OTDR and the cable plant and interprets the traces.
