  • Optical fibre comprising a bragg grating and tunability means
    Patent number: 6836593
    Abstract: The invention concerns an optical device comprising an optical fiber including at least an integrated component, a support including two fixing zones wherein the optical fiber is fixed respectively at the two zones located on either side of the component. The invention is characterized in that the support comprises, between the two fixing zones, at least a linking beam capable of bending and the device further comprises means for imposing a controlled bending to the beam, adapted to adjust the distance between the two fixing zones.

  • Optical fibre comprising a bragg grating and tunability means
    Publication number: 20020136493
    Abstract: The invention concerns an optical device comprising an optical fiber (10) including at least an integrated component, a support (40) including two fixing zones (30, 32) whereon the optical fiber (10) is fixed respectively at the two zones (12, 14) located on either side of the component. The invention is characterized in that the support (40) comprises, between the two fixing zones (30, 32), at least a linking beam (22, 23, 24) capable of bending and the device further comprises means (50) for imposing a controlled bending to the beam (22,23,24), adapted to adjust the distance between the two fixing zones (30, 32).

  • Process for mechanically removing the encapsulating material from a fiber-optic ribbon cable and tool for implementing the process
    Patent number: 6164163
    Abstract: The tool is constituted, on one hand, by a lower plate (12) traversed by a calibrated orifice, between an admission chamber (14) equipped with a roller (18) and a cutting plate (15) and, on the other hand, by an upper cover (22) also pierced by an opening (24) emerging in an inlet chamber (26) equipped with a roller (28). The upper cover is placed above the lower plate at distance that is variable so that the calibrated orifice and the opening are aligned, or can be offset heightwise.

  • Multi-channel mechanical splicing device for fiber-optic cables
    Patent number: 6033124
    Abstract: The device comprises a central spicing body serving to connect in situ two cable end plugs which fit into the splicing body. The central body has lower rails hollowed out therein and bears lateral shoulders for guiding and locking the end plugs constituted by a lower part and by an upper part fixed to one another by a press fit. The device has application in the in situ splicing of optical fibers.
