A micro-welder for optical fibers includes a stand having a central support surrounded by two lateral supports or beams. The beams are suitable for moving under drive from a bending movement about respective X-axes. The stand also supports a device for securing optical fibers on the beams and a device for accurately guiding the fibers on the central support. A low accuracy first displacement device is adapted to displace the beams to bring the fibers into end-to-end contact with each other by relative translation movement along their longitudinal Z-axis which is orthogonal to the X-axes. A high accuracy second displacement device is adapted for moving the beams to drive the fibers with accurate relative translation movements along the Z-axis. Two welding electrodes are provided and an optical device which includes a microscope for observing the ends of said optical fibers. The micro-welder second displacement device (25, 25') enables a continuous cycle of relative translation movements to be performed between the fibers (F, F') along the Z-axis in both directions. Further, the optical device includes a mechanism co-operating with the microscope (27) and enabling a single image of the optical fibers (F, F') to be obtained before and after welding as seen along two mutually orthogonal viewing directions.

Arc fusion splicer for optical fibers utilizing low and high accuracy

A spreader head for an optical fiber cable, the cable (10) comprising a central grooved core (11) with each groove (12) receiving a bundle (13) of optical fibers, the spreader head being constituted by a support part (20) surrounded by a ring (21) having outwardly open recesses disposed around its periphery and each receiving a cylinder (30), with each cylinder having at least as many axial orifices as there are optical fibers to a single bundle of optical fibers, and with each axial orifice having an optical fiber passing therethrough being extended by a flexible tube (50) for surrounding and protecting the corresponding optical fiber.
