Storage device for a spare length of an optical line
First Claim
1. 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 from which the spare length is led out by ends of the spare length through peripheral openings from which a free end can be pulled out, accompanied by reduction of the diameter of the turns, the device further comprising lateral guide walls at right angles to the central core and outer peripheral walls to limit the diameter of the turns, characterized in that the distance between the guide walls (6 to 10 and 11 to 16) is 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 substantially parallel to the guide walls, a removable end (32) being formed by the turn located radially outside, and a fixed end leading outside the plane of the turns over the outer turns to the innermost turn.

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radial distance round a central core and led out by its ends through peripheral openings from which one free end can be withdrawn, accompanied by reduction of the diameter of the turns.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.

13. A device for storing a spare length of an optical fiber, said device comprising:
-
a substantially cylindrical core having a cylinder axis; first and second lateral guide walls arranged transverse to the cylinder axis and attached to the cylindrical core so as to define an annular disk-shaped space between the guide walls, the guide walls being separated by a distance h; an outer peripheral wall attached to the lateral guide walls, said outer peripheral wall being arranged opposite the core; an optical fiber arranged in the annular disk-shaped space, said fiber being wound spirally around the core substantially in a single plane, said fiber being wound loosely around the core, said wound fiber having an innermost portion, an outermost portion, and an intermediate portion, the outermost portion exiting the annular space by passing through an opening in the outer peripheral wall, the innermost portion exiting the annular space by passing through a lateral guide wall. - View Dependent Claims (15, 17, 19, 21)
