Paper Abstract

Optical time domain reflectometers (OTDRs) are universal measurement apparatus, that makes possible to locate, measure the attenuation and reflected signals. Nowadays OTDRs are the most common devices, used in the field of fibre optic networks maintenance. The error of the reflectance measurement is about ±2 db for the most OTDRs. However it is possible to use these devices for control of attenuation growth. But additional analysis of the conditions of reflecting signals detection is required. Such analysis will be described in the present paper.
