ABSTRACT:
A storage device for a spare length of an optical line, comprising a flat storage space in which the spare length is wound at a radial distance round a central core and led out by its ends through peripheral openings from which one free end can be withdrawn, accompanied by reduction of the diameter of the turns. The device further comprises lateral guide walls at right angles to the central core and outer peripheral walls to limit the diameter of the turns. To permit the unobstructed withdrawal and sliding back in again of an end of an optical line despite an extremely flat construction, the arrangement is such that the distance between the guide walls (6 to 10 and 11 to 16) is slightly greater than the width of the optical line (1 to 5) and smaller than 1.3 times that width, the turns of the optical line extending spirally in a plane, the removable end (32) being formed by the turn located radially outside and the other fixed end leading outside the plane of the turns over the outer turns to the innermost turn.
