摘要： A molded fiber optic ferrule includes a ferrule body having an end face and a geometry feature integrally formed on an exterior surface of the ferrule body. The ferrule body defines a plurality of fiber bores for receiving end portions of optical fibers and at least one opening through the end face adapted to receive an alignment member for aligning the optical fibers with corresponding end portions of the opposing optical fibers of a mating multifiber ferrule. The geometry feature may include a geometric reference feature or an end face having a first surface normal to the longitudinal axis of the ferrule body and a second surface disposed at an angle relative to the first surface and the longitudinal axis. The geometric reference feature may be utilized to determine the angularity of the end face or the height of the optical fibers relative to the surface of the end face.

摘要： A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.

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 fiber optic connector includes a multifiber ferrule and at least one force centering element for applying a biasing force to the ferrule in the longitudinal direction without introducing a moment about a lateral axis. The connector further includes a coil spring for exerting the biasing force and a spring seat disposed between the coil spring and the ferrule. The rearward portion or the forward portion of the spring seat may be provided with a pair of outwardly extending protrusions that are laterally spaced apart to transfer the biasing force to the ferrule. Alternatively, the forward portion of the spring seat or the rear face of the ferrule may define a convex surface. Alternatively, the ferrule defines a convex surface in the direction of a first lateral axis and the spring seat defines a convex surface in the direction of a second lateral axis perpendicular to the first lateral axis.

摘要： A fiber optic distribution cable assembly having at least one factory-prepared mid-span access location for accessing and terminating optical fibers of the distribution cable includes a tether containing at least one optical fiber optically connected to an optical fiber terminated from the distribution cable and an overmolded body encapsulating the distribution cable and a portion of the tether to form the mid-span access location. The mid-span access location is provided with a preferential bend along an axis that is common to the distribution cable and the tether by a strength member positioned within the overmolded body and/or the overmolded body having a geometrical configuration that promotes bending along the common axis. The preferential bend reduces any path length differences between terminated optical fibers routed substantially on the common axis and optical fibers remaining within the distribution cable induced by bending, thereby preventing breakage of the terminated optical fibers.
