Optical fiber tensioning device and method of controlling the tension applied to an optical fiber |
摘要 |
An optical fibre tensioning device, receiving at its input an optical fibre from a traction device and capable of supplying the optical fibre from its output to a device for storing the fibre. The tensioning device comprises at least one fixed pulley on which the optical fibre is wound for a first length, and at least one movable pulley on which the optical fibre is wound for a second length. A device for measuring the tension applied to the fibre and a motorized device for moving the movable pulley interact with each other to control a distance (Dp) between axes of the pulleys in such a way as to automatically keep the tension applied to the fibre essentially constant.
