Answer :
Answer:
Optical Time Domain Reflector
Explanation:
Localized the break, supplies a graphical trace of where the break occurs in order to detect high loss splice point as far as 25 miles.
Answer:
The Optical Time Domain reflector
Explanation:
The Optical Time Domain
optical time-domain reflectometer is an optoelectronic instrument used to characterize an optical fiber. An OTDR is the optical equivalent of an electronic time domain reflectometer.
Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed
