Abstract

There is described a thermal compensator for a grading embedded in an optical fibre (6). The thermal compensator comprises first and second members fixedly connected to the optical fibre (6) at first and second fixing points either side of the grating. The first and second members have respective first and second bodies (9, 10) disposed parallel to each other and to the optical fibre (6), the first and second members being formed with juxtaposed surfaces disposed transversely to the longitudinal axis of the fibre (6). An expansion body (11) is captivated between the juxtaposed surfaces such that expansion of the expansion body (11) creates a force that urges the first and second fixing points towards each other, and contraction of the expansion body (11) creates a force that urges the first and second fixing points away from each other.
