Phase-sensitive optical time-domain reflectometry with pulse mode EDFA: Probe pulse preparation
A. O. Chernutsky, A. A. Zhirnov, A. K. Fedorov +6
Probe pulse preparation techniques play an important role for fiber-optic sensing. In this work, we investigate a setup for distributed sensors based on phase-sensitive optical tim…
Minimization of errors in narrowband laser phase noise measurements based on reference measurement channels
A. B. Pnev, K. V. Stepanov, D. A. Dvoretskiy +8
We propose a novel scheme for laser phase noise measurements with minimized sensitivity to external fluctuations including interferometer vibration, temperature instability, other…
Influence of the laser frequency drift in phase-sensitive optical time-domain reflectometry
A. A. Zhirnov, K. V. Stepanov, A. O. Chernutsky +5
The influence of the laser frequency drift on the operation of phase-sensitive optical time-domain reflectometry (-OTDR) systems is considered. Theoretical results based on a ne…
