The FOA Reference For Fiber Optics
The OTDR makes its measurements on the fiber, not the cable, so one must estimate the cable length. If you have a long length of cable with distances

The OTDR works like a radar, sending light pulses and analyzing reflections to show where issues exist. Industry studies show OTDR's advanced dynamic range and spatial resolution make it faster and more accurate than older troubleshooting methods. It is used to characterize and troubleshoot optical fibers by measuring the loss in a fiber link and pinpointing locations of potential issues such as breaks and splice losses. Optical time domain reflectometry (OTDR) is at the heart of quality assurance in the fiber optic network. This article, sisco will provide a detailed explanation of the working principles of OTDR, including the basic principles, measurement principles, and data.
