US Patent No. 7,258,493

Keyed fibre optic connector

A keying system for providing selective interconnection between a receptacle socket and a connector plug terminating an optic fibre, the connector plug adapted for insertion into the receptacle socket. The keying system comprises a raised boss configured to one of a plurality of predefined boss keying geometries and a cavity configured to one of a plurality of predefined cavity keying geometries. The boss is either in one of the receptacle socket or on a forward end of the connector plug and the cavity is formed in the other of the receptacle socket or the forward end of the connector plug. At least one of the predefined boss keying geometries matches at least one of the predefined cavity keying geometries. When the boss keying geometry matches the cavity keying geometry, the boss can be inserted into the cavity thereby interconnecting the connector plug with the receptacle socket. In this manner correct interconnections between connectors and other connectors or sockets can be insured thereby providing an enhanced level of security.

Back-to-back receptacle

A back-to-back receptacle and system for providing selective interconnection between a pair of optic fibres. The system comprises a receptacle comprising a pair of back-to-back receptacle sockets, with at least a first of the sockets configured to one of a plurality of predefined receptacle keying geometries, a first connector plug terminating the first optic fibre, the plug adapted for insertion into the first receptacle socket, the plug configured to one of a plurality of predefined connector keying geometries and a second connector plug terminating the second optic fibre, the plug adapted for insertion into a second of the back-to-back receptacle sockets. At least one of the predefined connector keying geometries matches at least one of the predefined receptacle keying geometries. When the receptacle keying geometry of the first receptacle socket corresponds to the connector keying geometry of the first plug and optionally the receptacle geometry of the second of the back-to-back receptacle sockets corresponds to the connector keying geometry of the second plug, the first plug can be inserted in the first socket and the second plug can be inserted in the second socket bringing the first optic fibre into axial alignment with the second optic fibre.

US Patent No. 10,473,859

Fiber optic connector

A fiber optic connector comprising a fusion assembly for strengthening a splice point. The fusion assembly comprises an elongate mechanical support positioned adjacent the splice point and snugly encased by a flexible tube. In one embodiment, a meltable adhesive in the form of a hollow tube is positioned over the splice point and the flexible tube comprises a heat shrinkable material. In another embodiment, the mechanical support is an elongate plate having a concave surface positioned adjacent the splice point and a C shaped cross section.

US Patent No. 10,175,430

Overmoulded furcation assembly with strain relief

An assembly comprises an optic cable comprising a plurality of optic fiber subunits each comprising at least one optic fiber encased in a fiber jacket and a plurality of aramid strands is disclosed. The assembly further comprises one or more blocks comprising a passage ways for receiving the optic fiber subunits and maintaining adjacent ones of the optic fiber subunits at a predetermined spacing. A housing is molded over the open end of the cable jacket, the aramid strands and the first end of the at least one block. A method of overmolding a transition between an optic fiber cable and a furcation jacketing is also disclosed wherein a mold comprises ribs arranged at right angles to an axis of the mold and such that aramid strands are prevented during injecting from reaching a surface of the mold.
