    摘要: Highly accurate centering of an optical fiber within a primary cladding deposited by a coating device is carried out by automatic regulation during the fiber-drawing process in order to optimize the mechanical properties of the fiber. The position of the coating device is controlled in dependence on the position of the fiber with respect to an origin of coordinates (O) determined by optoelectronic means. The frusto-conical lower end of the coating die is maintained at each instant by electronic and electromechanical means at the point (O') located at this level on the straight-line segment (OR) which joins the origin to the first point of contact of the fiber with the pulley used for guiding the fiber towards a storage drum.

    摘要: The invention provides a multi-channel optical coupler forming a single component which can be attached to the front panel of an equipment. A single central U-shaped optical fibre acts as a mixer waveguide. The terminal faces of this central waveguide are coplanar and optically connected to the single fibres or to the bunches of fibres, which constitute the incoming and outgoing channels, by two sets of single intermediate mixer fibres. Each intermediate fibre is equipped with a standard mechanical connecting element of detachable design, all these connecting elements being arranged in the same plane.

    摘要: The present invention relates to an end structure for a bundle of optical fibres arranged in a hexagon which comprises more particularly a cylindrical alignment member having one end which is adjacent to the end to be connected and comprises three regular points adapted to be fitted in three similar points of an identical end structure. This alignment member is previously angularly oriented relative to the bundle of fibres arranged in a hexagon so that its points have a given position relative to the hexagon formed by the fibres.

    摘要: This invention provides an optical fibers bundles connector comprising a male member and a female member which can be plugged into one another. In one of these members is included a single fiber of the same diameter as the bundles which are to be connected, which distributes the luminous flux issuing from the emitter bundle to the receiver bundle. An embodiment having the external dimensions of "Socapex 072 NX 65" electrical connectors is specially described.

    摘要: A multichannel coupler for connecting a plurality of input fibers to a plurality of output fibers which comprises a mixing fiber coupled to the pluralities of fibers. This mixing fiber is cut along a transversal cut and the two parts thus obtained are secured end to end. At least one of the surfaces delimiting the cut is ground for having a better distribution of the transmitted light onto the output fibers.
