Used to characterize optical fibers, the OTDR couples a laser and a detector and is based on the principle of reflectometry. The OTDR sends a pulse of laser light into one side of the optical fiber.

What is an OTDR? How does an OTDR work? What types of OTDRs are there? This helpful article explains the answer to these and many other OTDR-related questions.

An OTDR, or Optical Time Domain Reflectometer, is a device that is used to test and inspect the quality of a fiber cable. OTDRs are used in various cable applications to help inspect, …

Oct 9, 2025 · OTDR (Optical Time-Domain Reflectometer) is a critical tool for assessing fiber optic cable integrity. It works by launching high-powered light pulses into the fiber via laser diodes.

An Optical Time Domain Reflectometer (OTDR) is a precision tool used to detect faults and measure loss along fiber optic links by analyzing backscattered light from high-speed pulses.

Optical time domain reflectometers are instruments which measure the spatially resolved reflectivities and losses in optical fibers.
