Coil of very long optical fibre usable on a wire-guided missile

摘要

The coil according to the invention has normal dimensions, but contains a considerable optical fiber length. It is constituted by a main cylindrical support (12) about which is wound a first part (18) of the optical fiber (16), which is to be unwound by pulling. It is constituted by a first concentric, supplementary cylindrical support (14) placed within the main cylindrical support (12), a second part (20) of the optical fiber (16) being wound around said first supplementary support (14), the inner layer of the first part (18) of the optical fiber (16) being directly connected to an outer layer of the second part (20) of the optical fiber (16).
