An OTDR is precision instrument, used to locate faults in the fibers used for optical communication network. The links between access network and user networks requires application of these Otdr’s for its proper installations and maintenance.
OTDR’s are the testing equipment which is generally employed to test the fiber cables used in communication and networking fields. With the OTDR, we can get a snapshot of the newly installed fiber. This snapshot gives information the technician, about splice loss, measurement length and faults if any available in the fiber. OTDR are most effective in testing long cables approximately 250mts or 800 feet or cable plate with splices.
