Abstract

A high resolution, pulsed time-of-flight (TOF) reflectometer for measuring length and dynamic strain in a single mode optical fibre is reported. The object of the paper is to discuss the measurement principle and to present the results of some practical experiments, including a pull test on an OPGW cable and an elongation test on a standard telecommunication fibre with a dual-acrylate coating. Applications in the field of optical fibre-based strain sensing are also briefly reviewed.
