摘要： A gradual fiber cladding light stripper and its manufacturing method is disclosed to include an optical fiber that has a core, a cladding outside the core and an outer coating outside the cladding, the outer coating being removed by a preset cutting fixture to form a pre-stripping section, and a recoating section coated on the surface of the pre-stripping section at one time with a covering glue, the covering glue being irradiated and cured through a preset light curing device to form the recoating section with a gradual light stripping rate. The recoating section has a laser light input terminal with a relatively lower light stripping rate, and a laser light output terminal with a relatively higher light stripping rate.

摘要： A method for dividing an optical fibre comprises providing a hollow core optical fibre having a length, a cladding which comprises a microstructure, a hollow core surrounded by the cladding, and a negative pressure portion in which the pressure is below atmospheric pressure that extends over at least a portion of the length; and cleaving the hollow core optical fibre at a divide location within the negative pressure portion to divide the hollow core optical fibre into two parts and provide an end facet at the divide location on one or both of the parts.

摘要： A stripping tool configured to sequentially strip the layers of a cable, such as a fiber optic cable. The stripping tool includes multiple channels, each with a distinct role in stripping a layer of the fiber optic tool. The user sequentially moves the cable from channel-to-channel while operating the tool. At the conclusion of these operations the cable is appropriately stripped and ready for a subsequent operation.

摘要： An apparatus and method for performing optical alignment between optical waveguide elements in manufacturing a surface mountable optical module, in which a plurality of optical waveguide elements are mounted on a surface of a mounting substrate, is disclosed. A controller performs recognition of the interference pattern included in the image information received from the camera, observes parallelism between the substrate support and the mounting substrate and between the mounting substrate and the optical waveguide element using the recognized pattern, generates a control signal to control the transport device according to the observed parallelism, and transmits the control signal to the transport device to perform control of the optical waveguide element.

摘要： An optical fiber arrangement method includes: preparing an intermittently connected optical fiber ribbon including optical fibers arranged side by side at a first pitch larger than a fiber diameter; holding a non-connecting region of the optical fiber ribbon with a holder, where connecting portions intermittently connect the optical fibers extending out from the holder to each other; changing a width of the optical fiber ribbon in an interior of the holder; and arranging the optical fibers, extending out from the holder, with intervals of the optical fibers changed from the first pitch to a second pitch smaller than the first pitch by removing the connecting portions in a state where the holder is holding the optical fibers.
