WebAn Optical Time Domain Reflectometer (OTDR) is an instrument used to measure and create a visual representation of a fiber optic cable route. The measurement data can provide information on the condition and performance of fibers, as well as any passive optical components along the cable path like connectors, splices, splitters and multiplexers. WebOTDRs. An OTDR, or optical time domain reflectometer, is used in fiber cable testing and analysis. OTDRs detect bends, faults, or distortions. These user-friendly devices can also measure the length of cables and form a picture, or trace, of the cable’s condition. Renting OTDRs has never been easier with ATEC’s wide array of options.
