In a module for connecting and distributing optical fibers, intended for use in an optical distribution frame, the first end of each fiber is connected to a connecting socket and the second end of each fiber is connected to an optical distribution or transmission cable. The module includes an arm for guiding each fiber fixed by its first end to a support for a row of connecting sockets and connected by its second end to a cassette for coiling up each fiber. The cassette is articulated to the arm.

Optical fiber connection and distribution module intended for use in an optical distribution frame

The distribution frame and the method relate to a telecommunication installation in which optical fiber links are connected to connection members formed by sockets distributed on the front face of at least one distribution rack and in which jumpers provide the links between the connection members to which the links are individually connected. A robotized set of specialized tools is provided:

A process for metallizing a substrate part includes the following three steps: coating the part with a precursor composite material layer consisting of a polymer matrix doped with photoreducer material dielectric particles, irradiating the surface to be metallized of the substrate part with a light beam emitted by a laser, and immersing the irradiated part in an autocatalytic bath containing metal ions, with deposition of the latter in a layer on the irradiated surface. The dimension of the dielectric particles is less than or equal to 0.5 microns. The method is intended in particular for producing a metallized part including a substrate part consisting of a flexible film.

The low crosstalk device for connecting a multipair cable includes, on a stripped end part of the cable, rear support means provided with channels for retaining insulated wires of the pairs, front support means for guiding the wires to be connected to contacts and an intermediate part in which the wires cross over. The channels are in lengthwise lateral communication with one another to define a passage in which all of the insulated wires are gripped tightly together in a layer, near the sheathed cable, and are advantageously provided in a block which is held in position relative to the front support means. Application: male RJ45 connectors, cross-connection connectors, terminal strips.

The modular cross-connect panel for cable lines of cabled networks comprises a support assembly defining a vertical front portion and a horizontal rear portion, together with female connectors retained on the front portion and connected to the lines of cables fixed on the rear portion. In the panel said support assembly comprises two separate rigid supports referred to as a 'front' support and as a 'rear' support, together with two assembly columns fixed to the front support and releasably holding the rear support. The panel is applicable to a distribution frame for use in operating cable networks.

The process for the termination of electric cables (2) makes it possible, during the installation of the electric structure of a building, to prepare the final connection of each cable (2) by any random operator. Use is made of standardized cable termination means for provisionally storing the cable ends. The apparatus essentially comprises a block (1) within which is inserted, for each cable (2), a locking part (3) having a flexible tongue (5). The introduction of a cable (2) into its recess (7) is definitive as a result of the locking action of the tongue (5). The final connection takes place by means of a connecting hole (8) traversing the recess (7). It is therefore possible to prepare the connection of numerous cables with numerous electrical equipments to be supplied.
