    摘要: A fiber optic cable assembly with a floating tap is disclosed, wherein the assembly comprises a fiber optic cable having a cable fiber assembly, such as in the form of a ribbon stack. The assembly includes at least one network access point (NAP) for accessing at least one cable fiber in the cable fiber assembly and at least one strength area for example a strength member. At least one cable fiber is extracted from the cable fiber assembly and held by a transition assembly. A buffer conduit loosely contains the at least one cable fiber and guides it to an intermediate buffer conduit, which in turn guides the at least one cable fiber to a splice tube. The intermediate buffer conduit can translate relative to the splice tube. At least one tether fiber is spliced to the at least one cable fiber. Alternatively, the at least one cable fiber has sufficient length to serve as the at least one tether fiber so that splicing to another fiber is not required. Each strength member is covered by a movable member. A bonding structure bonds the cable fiber assembly, buffer conduit and movable member so that the cable fiber assembly can translate but not rotate relative to the cable within the NAP. This allows the tap point to “float” within the NAP when the cable fiber assembly needs to translate within the cable.

    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 relatively small fiber optic plug is provided to facilitate pulling of the fiber optic plug and an associated fiber optic cable through small passageways. The fiber optic plug may include a shroud that protects the fiber optic connector and that may further define at least one opening, and preferably a pair of openings. The openings are sized to receive portions of an adapter sleeve once the fiber optic plug is mated with a fiber optic receptacle. The fiber optic plug may also include a cap mounted upon and adapted to swivel relative to the remainder of the fiber optic plug to serve as a pulling grip during installation of the fiber optic cable. Further, the fiber optic plug may include a crimp band that is mechanically coupled to both the fiber optic cable and the plug body in order to isolate the fiber optic connector from torque otherwise created by forces to which the fiber optic cable is subjected.
