A transmission cable installation device is provided, which includes a protective sheath surrounding at least one transmission cable and having at least one longitudinal recess. A rigid element is inserted in one of said at least one recess. Also provided are a protective sheath and a profiled support suitable for being inserted in a recess in the protective sheath.

Transmission cable installation device

A cable packaging and unwinding device. The device enables the exact length of cable necessary for connecting two connection points to be unwound easily and quickly and a residual surplus length of cable to be stowed in a protected area, to prevent the cable from being subjected to any twisting or crushing and to obtain a reliable connection between the two connection points.

Packaging reel with an optical fiber unwinding device

A modular optical transmission cable which has several reinforcement and optical modules, each optical module having:

Structures of optical fiber cables self-reinforced against compression

Device for fixing, earthing end sealing the end of an optical cable, including at least one optical module, an outer jacket, especially made of relatively deformable plastic, having a cylindrical general shape, freely surrounding the optical module consisting of a set of adjacent fibres which are independent or preferably housed in a confinement sheath, and at least one reinforcing element having a high mechanical strength, in particular a high tensile strength, in order to take up and absorb the forces exerted on the cable without transferring them to the optical module, wherein it includes an immobilizing member operating by clamping the jacket from outside the latter, at least one hollow protective sealing plug capable of being placed around and possibly crimped onto a part of the reinforcing element that extends from the front end of the jacket which has been cut beforehand in order to strip the optical module, this plug including a flange, possibly protruding, bearing against a plane surface made on the end of the jacket, and a locking assembly for clamping over the plug, this locking assembly being formed by two oppositive jaws which mutually interact, closing together onto the external surface of the plug in a diametral plane passing through the axis of the latter, means being furthermore provided for closing together the locking assembly for clamping over the plug with respect to the member for immobilizing the jacket, so as locally to compress the latter by means of the flange of the plug, thereby achieving sealing with respect to the outside of the reinforcing element extending into the thickness of the sheath, parallel with its longitudinal axis.
