WebOTDRs can measure reflectance and total ORL for a fiber span. Return Loss (RL) of individual events, i.e. the reflection above the fiber backscatter level, relative to the source pulse scatter, is called reflectance. Return Loss of a fiber span is referred to as ORL. WebBy measuring backscatter from both ends of the fiber optic cable, one can redress the effects of differential attenuation, as caused by bends, splices, and connectors. The methodological principles behind the double-ended calibration are presented, together with a set of practical considerations for field
