Coupler for bundles of optical fibres, and method of producing the same

Abstract

Abstract Coupler for bundles of optical fibres (1, 2) which are twisted and partially united by controlled fusion of a part of the twisted region comprising a) an inner silica tube (6) surrounding the bundles of fibres on both sides of the twisted region, provided with resin plugs (7, 8) at each end, b) a protective casing separated from the inner tube by a layer (9) of silicone resin, with exit openings for the fibres formed by resin plugs (13, 14), and c) tubes (11, 12) for protecting the fibres near the casing. The resin of the plugs (7, 8) is polymerised by UV radiation, the casing is an outer tube (10) provided with plugs (13, 14) of resin polymerised with (UV) in which are embedded metal ferrules (15) and counterferrules (16) for crimping the ends of the tubes (11, 12) which are made up of extruded PTFE sheaths. Process for the manufacture of this coupler. <IMAGE>
