摘要:
A device for connecting on site two optical fiber transmission cables comprises a table for installation in a cable tunnel on the site and which is provided with a notch on its circumference, a tight box which bears against the table and whereof the two lateral faces have two openings in which are engaged the two cables to be connected, a splicing bench positioned in the table notch and on which are arranged tools for splicing the two cables, and means for joining the bench to the table.
摘要:
A device is provided for positioning optical fibers in a terminal connector for splicing two optical-fiber transmission cables, said device comprising an optical-fiber insertion piece having a central recess in which is fitted a terminal connector provided with grooves, and radial slits provided on the periphery of said insertion piece, and optical-fiber distribution means mounted freely rotatable on said insertion piece and having a longitudinal slit intended to come successively opposite each slit of said insertion piece, so that, by rotation of said distribution means, each optical fiber penetrates into a groove of said terminal connector through the slit of said distribution means positioned opposite a slit of said insertion piece.
摘要:
A machining tool comprises an annular structure having the same number of teeth as there are grooves to be machined, arranged radially in the structure, each tooth carrying a pin engaged in a curved slot. It also comprises a locking device constituted by a ring occupying a recess in the structure and a system of pawls carrying fingers which penetrate into the curved slots of the structure. It also incorporates a collar for controlling the locking device.
摘要:
A process and tooling to carry on said process for producing direct from extrusion an open groove plastic cylindrical section which consists in extruding the material around cylindrical pins arranged along a circle and protruding downstream with respect with the die opening and drawing the deformable structure along inner cutters located in the ducts formed by the pins to cut the material between the duct and the outside and further drawing said still deformable structure around flexible wires free to fill said slitted ducts.
摘要:
For splicing two optical fiber cables placed within a grooved dielectric support, centering and alignment of the fibers are carried out by means of centering pins inserted in longitudinal openings of an annular flange rigidly fixed to a terminal connector forming an extension of the grooved dielectric support, at least one of these openings being located at a distance from the cable axis which is greater than the radius of the cable.
摘要:
A head for the simultaneous laying of optical fibers within a grooved cylindrical support rod comprises a hollow tube through which the support rod is capable of passing longitudinally, a draw-ring rigidly fixed to and in axial alignment with the tube. A central opening of the draw-ring has an internal flange provided with radial projecting portions each adapted to rest on the bottom of one groove of the support rod. A member for inserting the optical fibers within the grooves of the support rod has a central opening which is in alignment with the central opening of the draw-ring and through which the support rod is displaceable in continuous translational motion.
摘要:
A head for laying optical fibers in the grooves of a cylindrical support is fixed to a plate carrying fiber reserves by means of a coupling permitting rotation. The support is maintained at a temperature above ambient temperature up to the laying head.
