OTDR Testers

OTDR (Optical Time-Domain Reflectometer) is a device that tests and monitors the performance of fiber optic cables form end to end. It sends light pulses through the fiber and measures the reflected signals to identify faults, splices, and signal loss. Acting like a “sonar for light,” an OTDR allows technicians to quickly locate issues and check the quality of a fiber link without cutting or disconnecting it, making it essential for telecom networks, industrial systems, and high-speed data transmission.
