Abstract: Optical-fiber trunks to be spliced are inserted into opposite ends of a downwardly converging longitudinal groove formed at the bottom of a channel member and are held in position by resilient tongues extending into that groove from an overlying retaining member. The latter, made of sheet metal, may be integral with the channel member but could also be a polygonal jacket enveloping an array of channel members accommodating individual fibers of an optical cable to be spliced. Instead of individual channel members so arrayed, an elongate body with several throughgoing channels and associated retaining elements may be used for cable splicing.

Abstract: To manufacture polarisation-maintaining optical fibres, a fibre (8) is directly and continuously irradiated with at least one beam (9) of UV radiation during drawing and before application of external coatings.

Abstract: Fluoride glass optical fibres are fabricated by minimizing the number of high-temperature operations. A tube comprising an external layer of a first fluoride glass of composition suitable to form the cladding of the fibre and an internal layer of a second fluoride glass of composition suitable to form the core of the fibre is prepared from a melt by a conventional rotational casting technique. Then, the internal layer is thinned by means of chemical etching at ambient temperature until the attainment of a ratio between the volumes of the two layers that corresponds to the ratio between the core and cladding diameters required for a single mode fibre, and the resulting tube is drawn.

Abstract: A duct for housing cables for underground telecommunications networks comprises one or more tubular elements (1) of a first plastic material, having helical ribs (2a, 2b; 3) on their inner surface. The ribs may also be formed as inserts into the material of the tubular element (1).

Abstract: A method of manufacturing dichroic antenna structures, which makes use of projector mounted on the mobile arm of a computer-controlled machine to project the shape of selective antenna elements on the surface of an insulating layer, clad with a metallic layer covered in turn with a photographic emulsion. Development and chemical etching of the exceeding conductive parts are then carried out.
