An Optical Time Domain Reflectometer (OTDR) is used in fiber optics to measure
the time and intensity of the light reflected on an optical fiber. More to the
point, it is used as a troubleshooting device to find faults, splices, and bends
in fiber optic cables, with an eye toward identifying light loss. An OTDR can
detect such light loss and pinpoint trouble areas, making repairs easy. The
more quickly trouble areas are identified and addressed, the less your fiber
optic network will suffer from data transfer problems. Test Equipment Connection
has new, used and refurbished OTDR units from the world's top manufacturers.
