Optical time delay reflectometer
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scatter… Web60KM Optical Time Domain Reflectometer OTDR VFL OPM OLS Red Light 4" TM290S SZ98.
