Abstract

A method of operating a distributed optical fibre sensor to measure one or more parameters of an environment as functions of position along a sensing optical fibre passing through the environment determines, measures or calculates an OTDR trace or attenuation profile of a sensing optical fibre in a distributed optical fibre sensor. The OTDR trace is to monitored to provide an indicia of properties of the sensing optical fibre in order to determine if the performance of the distributed optical fibre sensor in accurately measuring the desired environmental parameters is compromised. This allows adjustment of operation parameters of the distributed optical fibre sensor to maintain the performance at acceptable levels, or to automatically control the distributed optical fibre sensor in order to at least partly compensate for the changing properties. A distributed optical fibre sensor having such capability is also disclosed.
