摘要： Silica tubes and sleeves are used to protect fusion splices between the ends of the fiber coil and polarizing fibers. Use of silica for most of the subassembly components matches the coefficients of thermal expansion of the subassembly to that of the fiber coil, and also allows the coil to be annealed at extremely high temperatures. Annealing yields fiber coils of lowered birefringence, particularly when used with spun fibers. Ferrules are used to adjust the angular orientation of the fibers with respect to their planes of polarization.

摘要： A holder for annealing a fiber optic coil uses a silica ring on a silica substrate, or silica tubular coil, either of which may be directly incorporated into a coil subassembly for a Faraday-effect current sensor. The ring may be formed in a silica plate by sandblasting or grinding, or formed separately and adhered to the plate. In the tubular holder embodiment, silica tubes and sleeves are used to protect fusion splices between the ends of the fiber coil and polarizing fibers. Use of silica for most of the subassembly components matches the coefficients of thermal expansion of the subassembly to that of the fiber coil, and also allows the coil to be annealed at extremely high temperatures. Annealing yields fiber coils of lowered birefringence, particularly when used with spun fibers. Ferrules are used to adjust the angular orientation of the fibers with respect to their planes of polarization.

摘要： A coil of optical fiber can be self-supporting by bearing a layer of brittle thermoplastic adhesive that adheres adjacent convolutions of the fiber together. Because it is self-supporting, the coil needs no hub so that either end of the fiber can be unwound. Preferred thermoplastic adhesives are marketed in the optical industry as blocking waxes.

摘要： A connector for use with a cable containing a plurality of optical fibers supported in a flexible matrix and disposed parallel to each other, such as in a flat ribbon configuration. The connector includes a substantially flat housing member having a rear opening corresponding in size and shape to a cable to be received. The opening has associated therewith means for anchoring the cable. Passageways through the housing are provided for the individual fibers to be received and anchored within fiber retaining members such that the fiber ends are accessible at the front of the housing to be coupled to fibers within a mated connector. The fiber retaining members are in turn adapted to be received into an abutting relationship within an alignment means which maintains the mated fibers in axial alignment when the connectors are mated. The housing also has associated therewith a latching means on both sides of the flat housing adapted to corresponding members of the mated connector to align the respective members and to maintain the abutting relationship when the respective connectors are mated.

摘要： A filament organizer, for attaching an accessory to a section of filament, comprises a frame including a plurality of filament guides. The frame accommodates an accessory positioner adapted for sliding engagement therewith. A pair of spools, attached to the accessory positioner, has a section of filament extending from one to the other so that the filament passes around the plurality of filament guides of the frame to selectively position the section of filament. The accessory positioner includes an accessory cradle that moves from a retracted position to a proximate position. In its retracted position the accessory cradle receives an accessory to be placed in axial alignment with the section of filament. The accessory cradle then moves into the proximate position to attach the accessory to the filament section. Preferably, the filament is an optical fiber that includes a refractive index grating, and the accessory provides temperature compensation to stabilize the wavelength and facilitate wavelength tuning of the grating.

摘要： A connector structure for separably connecting optical fibers includes a pair of precision sleeves, each of which is adapted to surround one of the fibers such that the ends thereof are in axial alignment. A housing fitted around the sleeves maintains that alignment. After each fiber is fitted into a matching sleeve such that end portions thereof protrude through the sleeve, the fiber is permanently anchored therein to prevent relative motion and the end of the sleeve and fiber combination is ground substantially flat and perpendicular to the fiber axis. The end of the combination is then polished under a predetermined set of conditions selected to be consistent with predetermined wear characteristics of the sleeve and fiber in which the fiber is less wear resistant than the sleeve. During the polishing operation the fiber end becomes convex and recessed within the sleeve. A pair of fibers may thus be optically coupled by butting together the ends of two sleeves within an outer housing. The recess in the fiber end precludes scratching or chipping of the fiber due to contact with other members.
摘要翻译： 用于可分离地连接光纤的连接器结构包括一对精密套筒，每个精密套筒适于围绕其中一个纤维，使得其端部处于轴向对准。 套在袖子周围的外壳保持对准。 在每个纤维被装配到匹配的套筒中，使得其端部通过套筒突出，纤维永久地锚定在其中以防止相对运动，并且套筒和纤维组合的端部被研磨成基本上平坦且垂直于纤维轴线。 然后将组合的末端在预定的一组条件下进行抛光，该条件选择为与套筒和纤维的预定磨损特性一致，其中纤维比套筒的耐磨性更小。 在抛光操作期间，光纤端部变得凸出并凹入到套筒内。 因此，一对纤维可以通过将外部壳体内的两个套筒的端部对接在一起来光学耦合。 光纤端部的凹槽由于与其它部件的接触而妨碍了光纤的划伤或破损。
