Paper Abstract

In the paper, the analysis of the application of a tunable semiconductor laser working in 1550 nm band in a C-OFDR construction is presented. The laser was tuned in narrow 0.24 nm range by a PZT element and in wide 70 nm range by a stepping motor. The narrow range was used for signal separation from measurement points laying along optical fiber. The wide range can be used in to separate signals from branches of a fiber optic sensor network. The reflectometer was used for signal detection from quasi-distributed sensors network. Measurements were carried out for different distances of point fiber optic sensors from the reflectometer. As the models of point sensors air cavities were used. The influence of tuning range of the laser on measurement errors is discussed.
