Abstract: 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.

Abstract: A modular optical transmission cable which has several reinforcement and optical modules, each optical module having:a sheathed optical fiber, coated with:an intermediate decoupling layer, and witha rigid shell forming a microcarrier,a reinforcement module being associated with an optical module, the modules being molded in an external sheath. A flexible reinforcement module is associated with at least one optical module that is self-reinforced against compression in order to obtain a cable having high flexibility combined with high compressive strength. The disclosure can be applied in the field of optical fiber cables and especially that of the reinforcement structures of such cables and fibers.

Abstract: 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
