摘要： The invention relates to an optical zooming system for use on fusion splicers. The system may include a lens, camera, and a zooming mechanism, which allows the camera and the lens to move relative to each other. The zooming mechanism may be set to a “zoom out” configuration for aligning the cores of fibers. The zooming mechanism may also be set to a “zoom in ” configuration for adjusting fibers with a large diameter.

摘要： An optical fiber placement surface has formed thereon width-directional position restricting sections for partially restricting the position of an optical fiber ribbon in a width direction perpendicular to the axial direction of the optical fiber ribbon. A portion other than the width-directional position restricting sections serves as a width-directional position non-restricting section that does not restrict the position of the optical fiber ribbon in the direction perpendicular to the axial direction of the optical fiber ribbon. A pressing member is formed at a portion corresponding to the width-directional position non-restricting section. On the other hand, the pressing member is not formed at positions corresponding to the width-directional positional restricting sections. Thus, the optical fiber ribbon is not pressed at the width-directional positional restricting sections. Portions at which the optical fiber ribbon is not pressed by the pressing member are defined as non-main pressing sections.

摘要： A method for fusion-splicing optical fibers and a fusion splicer are provided, which enable preventing a fusion spliced portion from disconnecting when the optical fiber is removed from the fusion splicer. A fusion-splicing method for optical fibers comprises: holding optical fibers and on optical fiber holding parts respectively provided on a pair of movable stages; butting ends of optical fibers by bringing the pair of movable stages mutually closer; fusion-splicing butted optical fibers to form a fusion spliced portion S; carrying out a proof test, the proof test including applying a tension to the fusion spliced portion S by moving the pair of movable stages so as to distance them from each other; and bringing the pair of movable stages mutually closer by a predetermined distance upon completion of the proof test.

摘要： A multicore fiber 1 includes a plurality of cores 3 disposed at predetermined intervals and surrounded by a cladding 5. The multicore fiber 1 also includes a marker 7 formed apart from the cores 3. The refractive index of the marker 7 is different from those of the cores 3 and the cladding 5. For example, the marker 7 may be made of a material having lower refractive index than that of the cladding 5. In this case, for example, the cores 3 may be made of germanium-doped quartz. The cladding 5 may be made of pure quartz. The marker 7 may be made of fluorine-doped quartz. Further, the marker 7 may be an empty hole.

摘要： An optical interconnect can be located between a first optical guide with a first optical guide end and a second optical guide with a second optical guide end. The first optical guide and the second optical guide can each have an operational wavelength, which can be substantially the same such that light of such a wavelength can propagate through the optical interconnect. The optical interconnect can include a pressure-sensitive material with a first region with a first refractive index at the operating wavelength. The pressure-sensitive material can include a second region with a second refractive index at the operating wavelength located between the first optical guide end and the second optical guide end. The second region can be induced by a mechanical pressure applied between the first guide end and the second guide end.

摘要： Apparatus and methods are described herein for cleaving an optical element at a defined distance from a splice (or other reference point/feature) of the optical element within a desired precision and/or accuracy. In some embodiments, a method includes receiving an indication of a location of a feature in an intermediate optical assembly visible within an image of the intermediate optical assembly. The feature can be for example, a splice. A position of the intermediate optical assembly is translated relative to a cleave unit based on the indication. After translating, the intermediate optical assembly, the intermediate optical assembly is cleaved to form an optical assembly that has an end face at a location disposed at a non-zero distance from the location of the feature. In some embodiments, the location of the feature can be determined with an image recognition system.
