Abstract

This application relates to a fibre optic cable () suitable for use with a distributed fibre optic sensor apparatus (). The fibre optic cable includes at least one optical fibre () and a force transformer () mechanically coupled to the at least one optical fibre. The cable may also include at least one cladding later () and/or a compliant material (). The cable may be surrounded by a jacket layer (). The force transformer () is configured to transform transverse forces due to dimension changes of the cable arising from a temperature variation of the cable into longitudinal forces to counteract the longitudinal component of said dimension change over a tuned temperature range. In this way optical path length changes due to a change of temperature can be reduced or eliminated providing a cable which is insensitive to temperature.
