Optical Time Domain Reflectometer

OTDR measurement allows a complete certification of the physical layer of a fiber optic link, by differentiating the global loss of the link under test. This measurement is mandatory to check the deploiment quality of a fiber optic network, or in cas of troubleshooting.

Throught itslarge range of OTDR modules, Viavi (formerly JDSU) offers the best solution to test the whole fiber optic network.
May the fiber be singlemode or multimode, short or long distance, point to point or with splitters, and even with active fiber, Viavi has the test module adapted to your need.
