  • Device for Leakproof Connection of Telecommunication Cables and Production Method Thereof
    Publication number: 20090045591
    Abstract: A sealed connection device (18) for telecommunications cables comprises a tubular plug (20) for being received in an inlet of a protective box for telecommunications, with a plurality of tubes (22) each designed to receive at least one telecommunications cable (34). The tubes (22) are disposed longitudinally in the plug (20) so as to pass right through it, and a resin (28) is cast between the tubes (22) so as to provide both mechanical retention of the tubes in the plug and sealing of the connection device.

  • Degreasing device particularly for optical fibers
    Patent number: 5526833
    Abstract: A device for degreasing pieces such as optical fibers of a stripped cable comprises a tank containing a liquid solvent in which the pieces are immersed, a pressurized gas container having a gas outlet nozzle, a receptacle for holding the container vertical with the nozzle at the bottom, and a diffuser for gas passing from the nozzle into the liquid solvent below the pieces. The gas diffused into the solvent is cold and causes turbulence of the solvent. The grease is detached from the pieces and falls into a cavity.

  • Apparatus for the oblique cutting of one or of several optical fibers
    Patent number: 5368211
    Abstract: An apparatus cuts one or several optical fibers obliquely. The cutting edge (6) creates the beginning of a break on the fiber that has first been subjected to a torsion and to a tension. The fiber is immobilized upstream of the cutting point. Then, the fiber is tightened downstream from the cutting point. Next, a tension is exerted on the part of the fiber or fibers located between the application of the tightening (3,4). The tightening also involves an exertion of a torsion force upon the optical fiber.
