Otdr coding
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… WebThis is an simple Online Viewer for SOR Files (Standard OTDR Record- Telcordia SR-4731, issue 2 standard). This data Format ist used to store OTDR fiber data.
