Abstract

The present invention relates to an optical component, which comprises an optical fibre, which has a minimal functional arc radius in each point thereof, and which includes a thermally compensated portion, and a Bragg grating provided in a region of the thermally compensated portion. The optical fibre component comprises furthermore a temperature-compensating structure, which holds the thermally compensated portion of the optical fibre under tension in a linear direction for athermalizing the Bragg grating, and a housing for mechanical protection of the Bragg grating, which is provided with at least a first lead-through, and which housing has a maximal extension in the linear direction from a first housing end to a second housing end. The first lead-through has an exit end located outside the housing and an entrance end located inside the housing. The optical fibre furthermore includes at least a first connecting portion, which extends from a first end of the thermally compensated portion to and through the first lead-through, and at least a first exit portion which extends from a lead-through exit end of the first connecting portion. The first lead-through is located and arranged such that the first exit portion is bendable to the minimal functional arc radius without protruding more than half the minimal functional arc radius in the linear direction beyond the first housing, also when a shorter exit portion is extended to a length equal to the circumference of a circle with the minimal functional arc radius.
