What Does OTDR Stand For?

OTDR stands for Optical Time Domain Reflectometry

Optical Time Domain Reflectometry (OTDR) is a testing method used in fiber optic networks to analyze the integrity and performance of optical fibers. By sending light pulses down the fiber and measuring the time and intensity of reflected signals, OTDR provides essential data on fiber length, loss, and location of faults or splices. This technology is crucial for maintenance, troubleshooting, and optimizing fiber optic installations.
