摘要： Eccentricity of a optical fiber installed in a passageway of a ferrule is minimized by imposing a force on the end of the optical fiber projecting from the passageway at the ferrule end face to push the optical fiber to a desired position in the passageway, prior to curing an adhesive used for fixing the optical fiber in the passageway, so as to compensate for eccentricity of the passageway. In one embodiment, the force is imposed on the optical fiber by hanging a weight on the optical fiber. In another embodiment, the force is imposed on the optical fiber by using a pressurized jet of fluid. The point of application of the force, the magnitude of the force, and the viscosity of the adhesive are selected such that minimal optical fiber bending occurs, thereby assuring that the optical fiber is positioned at the desired position in the passageway for an appreciable distance from the ferrule end face along the passageway.

摘要： A method for polishing the distal end of a fiber optic connector. The distal end is first polished in the presence of an aqueous slurry comprising two different powders to bring a glass surface and a ferrule surface to a substantially common plane, and subsequently polished in the presence of an acidic solution to prevent the attachment of hydrated silica particles to the ferrule face.

摘要： Fiber optic distribution cables and methods for manufacturing the same are disclosed. The fiber optic distribution cables present one or more optical fibers outward of the protective covering for distribution of the same toward the subscriber. In one fiber optic distribution cable, a length of distribution optical fiber that is removed from the distribution cable and presented outward of the protective covering is longer than the opening at access location. In another embodiment, a demarcation point is provided for inhibiting the movement (i.e., pistoning) of the distribution optical fiber into and out of the distribution cable. In still another embodiment, an indexing tube is provided for indexing a tether tube within the indexing tube for providing the distribution optical fiber with a suitable excess fiber length. Additionally, other embodiments may include a fiber optic distribution cable having a dry construction and/or a non-round cross-section.

摘要： The present invention provides a cable assembly comprising a flexible network access point that includes a flexible cover over a mid-span access location, providing environmental protection for the mid-span access location and facilitating installation of a distribution cable. Subsequent to installation, the mid-span access location is exposed and accessed by pulling a ripcord, for example, thereby removing a portion of the flexible cover. This exposes one or more connectors, which may be single or multi-fiber connectors, that are configured to receive the receptacles of one or more drop cables and/or tethers. Thus, a semi-hardened, selectively-usable closure is provided.

摘要： An adjustable tether assembly for a fiber optic distribution cable includes a tether cable and an overmolded housing secured at the end of the tether cable having at least one connector port. The tether assembly is attached to the distribution cable such that the position of the connector port is adjustable along the length of the distribution cable for mitigating differences between the pre-engineered span length distance and the actual span length distance following installation of the distribution cable. A method for mitigating a span length measurement difference in a pre-engineered fiber optic communications network is provided that includes optically connecting an adjustable tether assembly at a mid-span access location of a fiber optic distribution cable and positioning a housing secured at the free end of a tether cable having at least one connector port at a desired location in the network to compensate for the span length measurement difference.

摘要： A ferrule assembly having highly protruding optical fibers and a corresponding method of efficiently, precisely and repeatedly fabricating the ferrule assemblies are provided. In this regard, a ferrule assembly is provided that includes a plurality of optical fibers extending at least about 3.5 μm beyond the front face. The end portions of the optical fibers of the ferrule assembly may also be substantially coplanar with the end portions of the optical fibers differing in position from one another by no more than 100 nm. The ferrule assembly may be efficiently fabricated by polishing the optical fibers to a desired protrusion without first grinding or polishing the optical fibers to be flush with the front face of the ferrule. The ferrule assembly may be even more efficiently fabricated in instances in which the ferrule includes at least one polishing feature, such as an outwardly extending pedestal or a recessed portion.

摘要： A multifiber ferrule is provided that includes a ferrule body that defines at least one elongate hole opening through the front face of the ferrule body that, in turn, includes a lead-in portion proximate the front face for guiding the respective alignment member into the elongate hole. The ferrule body at least partially defines one or more elongate holes, such as a guide pin hole or an alignment groove, each having a longitudinal axis extending therethrough. Each elongate hole includes the lead-in portion proximate the front face and an adjacent alignment portion. The lead-in portion expands radially outward from the longitudinal axis in a direction extending from the adjacent alignment portion to the front face of the ferrule body. As such, the opening of the lead-in portion through the front face of the ferrule body is larger in lateral cross-section than the opening of the lead-in portion into the adjacent alignment portion. The lead-in portion is therefore capable of guiding the respective alignment member into the adjacent alignment portion that, in turn, is sized to snugly receive the alignment member, thereby serving to properly align the ferrule with the alignment members. In addition, the lead-in portion of each elongate hole defined by the multifiber ferrule serves as a receptacle for dirt or other particulates that are transferred from the alignment member as the alignment member is inserted into the respective elongate hole.
摘要翻译： 提供一种多光纤套圈，其包括套圈本体，其限定穿过套圈本体的前表面的至少一个细长孔，该细长孔又包括靠近前表面的引入部分，用于将相应的对准构件引导到细长的 孔。 套圈主体至少部分地限定一个或多个细长孔，例如引导销孔或对准槽，每个具有延伸穿过其中的纵向轴线。 每个细长孔包括靠近前表面的引入部分和相邻的对准部分。 引导部分在从相邻的对准部分延伸到套圈主体的前表面的方向上从纵向轴线径向向外扩展。 因此，引导部分穿过套圈主体的前表面的横截面比通向相邻对齐部分的导入部分的开口大。 因此，引入部分能够将相应的对准部件引导到相邻的对准部分中，该相应的对准部分又被调整为紧密地接纳对准部件，从而用于使套圈与对准部件正确对准。 此外，由多光纤套圈限定的每个细长孔的引入部分用作用于污垢或其它微粒的容器，当对准构件插入到相应的细长孔中时，其从对准构件传送。

摘要： A splicing connector and an associated splice mechanism are provided to splice first and second pluralities of optical fibers without buckling the optical fibers. The connector includes a housing and a retainer disposed of at least partially within the housing which defines a channel through which a plurality of optical fibers extend. The connector also includes a clip for securing the optical fibers within the retainer such that the end portions of the optical fibers are exposed through the forward end of the housing in preparation for splicing the optical fibers. Further, the connector includes a spring for urging the retainer and the optical fibers secured within the retainer toward the forward end of the housing, thereby permitting the optical fibers to be spliced without buckling the optical fibers.
