Patent number: 4387957Abstract: A connector for optical fibres, said connector including two groups of th cylindrical support rods, 13A, 13B, 13C, 14A, 14B, 14C, all of same diameter and guide means to keep these two groups of three rods side by side and in contact with each other so as to provide a central passage to house the optical fibres. The guide means include a group of three or four bearings held coaxially with one or two central bearings 20A, 20B, surrounding the two groups of rods on either side of their plane of contact 17 with very little play and with one end bearing 18, 19 surrounding each group of three rods with the same or a slightly greater play at a point distant from the plane of contact. Application to optical fibre transmission lines.Type: GrantFiled: November 10, 1980Date of Patent: June 14, 1983Assignee: Societe Anonyme dite: Compagnie Lyonnaise de Trandmissions OptiquesInventor: Georges Mignien

Patent number: 4345137Abstract: A method of welding several optical fibers end to end in layers in a common welding plane. Each fiber (31) includes a bared portion and a covered portion. The method is applied by a device including:(a) a microplasma welding torch (40) with a vertical axis movable in said weld plane;(b) a supporting block (39) with: parallel positioning grooves for positioning the bared portions of the fibers; an opening (42) in the neighborhood of the weld plane; and a chamber (43) for slowing down the gases of the plasma disposed below said opening and connected thereto; and(c) components for gripping the covered portions of the fibers said gripping components being constituted by supports (11, 12) provided with parallel optical fiber positioning grooves. A positive pressure difference is set up between the upper portion and the lower portion of the fibers. The fibers are translated parallel to the axes of the optical fibers.Type: GrantFiled: January 3, 1980Date of Patent: August 17, 1982Assignee: Compagnie Lyonnaise de Transmissions OptiqueInventors: Georges Mignien, Francis Gauthier

Patent number: 4227951Abstract: A method of splicing optical fibres which are previously disposed in a layer in a cable.The fibres 1 are released from the tape (2 and 3) in which they are trapped; they are broken and laid in positioning V-grooves (5A) of a plate 12. Adhesive is applied to the fibres and a pressing cover 17 is laid thereon. The adhesive is allowed to set, then the assembly thus formed is sawn in parallel planes (19,20). The remaining portions on either side of the saw planes are then placed end to end again and are pressed against each other and fixed in position. Application to splicing optical fibres of cables formed by assembling flat tapes.Type: GrantFiled: May 29, 1979Date of Patent: October 14, 1980Assignee: Compagnie Lyonnaise de Transmissions OptiquesInventor: Georges Mignien

Patent number: 4217031Abstract: A mechanical device for connecting optical fibres together by single or multiple connections with little attenuation loss. The connector has a body in the form of a cylinder, end pieces which support three cylindrical rods enclosing the fibre and disposed in guiding V-grooves, covers associated with the end pieces by spring washers which enable the cover to be longitudinally snap-fitted onto the body and a deformable blade which presses transversally against the rods.Type: GrantFiled: August 30, 1978Date of Patent: August 12, 1980Assignee: Les Cables de LyonInventors: Georges Mignien, Christian Millet

Patent number: 4142777Abstract: A connection device allowing optical fibres manufactures in a factory to be connected together in the field by end pieces. Each end piece comprises a fibre clamped between three cylindrical rods which lie tangential to each other in pairs and encompass a fibre in their central clamed. The end pieces are disposed on either side of a mounting assembly comprising alignment structures constituted by V-shaped grooves in which the fibre and the rods are inserted. Means are provided to press on the rods transversally. According to one variant, this function is fulfilled by elastomer cylinders compressed by clamping the plates of the mounting assembly. Application : Optical fibres for telecommunications.Type: GrantFiled: May 18, 1977Date of Patent: March 6, 1979Assignee: Societe Anonyme Dite: Les Cables de LyonInventors: Francis Gauthier, Georges Mignien
