Abstract: A connector for optical fibres including two male ferrules mounted at the end of each of the fibres which are to be connected and a female reconstituting connector having a longitudinal bore for supporting and aligning the two ferrules face to face.
Abstract: A ferrule of a connector for single-mode optical fibers with polarization maintenance is provided and comprises a tubular outer body which has at its front end a wall that is conical in profile, an inner cylindrical elements inside which an optical fiber can be immobilized, particularly by gluing, said inner element protruding from said end of the outer body, said outer body comprising radial holes for the insertion of devices such as piercers for mechanically centering the inner element in the outer body. The connector includes a socket (18) attached in rotation around said body (1) and means (2) for immobilizing said socket, preferably by gluing, on said body, said socket being, moreover, equipped with an indexing reference (19).
Abstract: The invention relates to an attenuator for single-mode optical fibers entailing two male ferrules attached to the end of the fibers to be connected, and a female access coupler in the central part of which is a spherical thrust bearing body. A transverse axial orifice is provided in the thrust bearing body and a contact projection engages each of the male ferrules. Each male ferrule has an axial tubular protuberance that can be inserted into the orifice of the thrust bearing body and an annular groove set back from the protuberance and surrounding the back part of the latter, which groove has a wall, preferably conical in profile.
Abstract: An optical fiber connection base for receiving an optical fiber positioned and centered in a ferrule having a tubular axial extension with a passage into which the fiber is introduced and immobilized with its front end coplaner with the front end of the tubular extension. The base has a unitary tubular body with a front support. An interior projection having a convex bearing surface extends rearwardly into the bore of the body from the rear face of the front support. The front support and projection have an axial opening to receive the tubular extension of a ferrule inserted into the body from the rear of the bore. An annular conical wall of the ferrule seats on the covex bearing surface of the body along a circular line of contact at a predetermined distance from the front face of the front support, so that the front end of the ferrule is centered and coplaner with the front face of the support.
Abstract: A method of mechanically locking an interior element in an outer body with deformable material. The deformable material is permanently deformed against the interior element through circumferentially spaced radial holes in the outer body. This forms a core of deformed material between the inner element and outer body, with some deformable material in each opening. The radial position of the inner element can then be adjusted without shifting the inner element axially, using punch or press elements which are inserted in selected radial openings to further deform the material and thus adjust the inner element radially. The method is particularly useful for centering an optical fiber fixed within an inner element, by so adjusting the radial position of the inner element in an outer ferrule body.
Abstract: A device makes a non-permanent connection between two optical fibers each fixed into a respective fiber holding device from which a bared end of the fiber protrudes. The device comprises a socket member featuring a guide member to accommodate the aligned bared fiber ends. A clamp member in line with the guide member immobilizes the bared fiber ends by clamping them against the guide member. Two mobile plug members are each adapted to interlock nesting fashion with the socket member, one on each side of the guide member. Their axes are at a predetermined angle to the guide member. Each plug member comprises a front surface through which it comes into an abutting and supporting relationship with the other plug member. At a rear end of a central channel in the plug member is a receptacle for the fiber holding device. There is an orifice at the front end of this channel slightly larger than the diameter of the bared fiber end.
Abstract: The invention concerns a hermetic coaxial connector of the type intended to be attached to a panel to ensure hermetic coaxial traverse of said panel, comprising a central conductive contact housed with interposition of an insulator in a housing, forming an external conductor, provided with means of attachment to a panel, a sealing joint between the external conductor and the panel, and an insulating glass bead sealed to the central contact and to an annular ring housed at least partly in a recess of the housing. The ring presents a staggered configuration comprising an axial annular span connected by the glass sealing bead (7) to central contact (5), an axial span in contact with a corresponding span of the housing, a radial span supported against the corresponding span of the housing and a radial span in contact with the sealing joint (11) interposed between the ring and the panel (2).
Abstract: A connector ferrule body has a flat inner surface perpendicular to its axis and at one end of an axial cavity in the ferrule body. A hub has an opening in which an optical fiber is fastened so the fiber extends perpendicular to a flat end face. The flat end face of a hub is seated on the flat surface of the ferrule body and held against the flat surface of the ferrule body by a spring. Openings in the side wall of the ferrule body permit insertion of tools to slide the hub radially on the flat surface of the ferrule body to precisely position the optical fibre within the body. The spring holds the hub in the adjusted position.
Abstract: A coaxial support for an interior conductor includes at least four thin dielectric plates (d) mechanically preformed and which are seated in slits of an exterior conductor element (n), and automatically center and immobilize an interior conductor element of reduced section (i). The support, which has a relatively significant length with respect to the diameter of the exterior conductor, has great rigidity in the transverse and longitudinal directions.
