Abstract
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).
Claims9
A coil for a long optical fibre comprising:
- (a) a main cylindrical support;
- (b) at least one supplementary cylindrical support placed within and concentric with the main cylindrical support;
- (c) a long optical fibre having:
- a first fibre part wound in layer-by-layer form on the main cylindrical support and having an inner layer thereof wound directly onto and in contact with the main cylindrical support and an outer layer thereof on the winding of said first part;
- and a second fibre part wound in layer-by-layer form on said supplementary cylindrical support and having an inner layer thereof wound directly onto and in contact with the supplementary cylindrical support and an outer layer thereof on the winding of the second fibre part, the fibre of the outer layer of the second fibre part being directly connected to the fibre of the inner layer of the first fibre part.
