Abstract: The invention relates to a device (1, 1?, 1?) for cooling an optical fiber (13), including two portions (20, 29), each of the portions (20, 29) including at least one receiving surface (204, 294) on which a half-channel (240, 2490) is provided, such that, once the two portions (20, 29) are placed in contact at the receiving surface (204, 294) thereof, the two portions (20, 29) form a main through-channel for accommodating the passage of the optical fiber (13), characterized in that each of the portions (20, 29) is a block of a thermally conductive material and in that at least one (20) of the portions includes a cylindrical secondary channel (209), which is in fluid connection with a plurality of openings (2046) distributed along the half-channel (2040) of said portion (20), in order to form a heat-transfer fluid distribution chamber for the plurality of openings (2046).

Abstract: The invention relates to a device for guiding an optical fiber (2), which is intended to be mounted on a vertical tower (T) for manufacturing an optical fiber (2), the fiber being produced from an oven (18) located at the upper portion of the tower (T) and being moved vertically downward relative to the tower (T), the guide device (1) being located downstream of the oven (18), the device including: a first guide pulley (10), at least one surface (1220) for twisting the fiber (2), which is located downstream of the first guide pulley (10), a second guide pulley (14) located downstream of the at least one surface (1220) for twisting the fiber (2), and a deflecting pulley (16), the distance (C) between the first guide pulley (10) and the at least one surface for twisting the fiber (1220) being greater than the distance (D) between the at least one surface for twisting the fiber (1220) and the second pulley (14), the device being characterized in that it timber includes a second surface (1222) for twisting the op

Abstract: A flexible energy-transfer ribbon that includes a magnetised tape (3) composed of an elastomer material forming a matrix in which are embedded particles that impart to it a permanent magnetism oriented in the direction of the thickness of the said tape, at least one energy-transfer device (2) lying along the support tape, and a coating material (1) in which the (or each) energy-transfer device is embedded and which adheres to the magnetised tape. The invention is notable in that the magnetised tape is subdivided into successive sections (31) of such a length that dimensional change phenomena induced in the magnetised tape, in particular under the effect of temperature differences, induce stresses between the magnetised tape and the coating material which are sufficiently small to prevent weakening of the adhesion between the said magnetised tape and the said coating material. The invention applies in particular to small-signal optical or electrical links between mobile devices, particularly in rotation.
