OTDR

An Optical Time Domain Reflectometer (OTDR) is a specialized instrument used in fiber optic testing and troubleshooting. It operates by sending short pulses of light into a fiber optic cable and measuring the time and intensity of the light that is reflected back.

OTDRs are essential tools for fiber optic technicians and engineers to characterize the quality of installed fiber optic cables, locate faults, determine splice and connector losses, and verify the overall performance of the fiber optic network. They are commonly used during installation, maintenance, and troubleshooting of fiber optic systems.
