Distributed Birefringence Measurements Using Polarization Correlation in Phase-Sensitive OTDR

European Conference on Optical Communications, ECOC, Cannes, France, 21-26 sept. 2014.A method based on phase-sensitive OTDR is proposed for distributed birefringence measurements along optical fibres. A high accuracy is experimentally demonstrated, enabling the characterisation of single-mode fibres with a minimum detectable birefringence of the order of 10-7European Cooperation in Science and Technolog
