With an optical time domain reflectometer (OTDR) one can localise reflective or loss inducing effects along a fiber optic link. Reflective losses arise for example from poorly matched optical connectors or at a transition from one fiber type to another. Attenuating losses can be introduced by the fiber itself, any interconnecting devices or by bending the optical fiber above a certain threshold or at faults along the fiber length. AMS Technologies can provide low cost and lightweight OTDR systems for telecom/datacom applications as well as high definition OTDRs at user specified
OTDR (Optical Time Domain Reflectometer) technology measures attenuation as well as (unwanted) back reflections along an installed fiber link. The Photon Counting OTDR available from AMS Technologies allows for very precise location of reflections (within centimeters) in an optical fiber link by using detection that is very sensitive in the time domain. OTDRs are available for many wavelengths, starting from the visible and going up to 1700 nm.
