Abstract
A fibre sensing apparatus () comprises an interrogation unit () to interrogate a sensing fibre with optical radiation, and to detect an optical signal returned from the fibre, and processing circuitry (). A portion of the fibre may be excited with a test signal. The processing circuitry comprises an assessment module () to analyse the optical signal returned from the excited portion of fibre, and to determine at least one operational characteristic of the apparatus based on the detected optical signal.
