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.

摘要： A fiber optic distribution cable assembly includes a distribution cable having at least one predetermined mid-span access location and a tether for mitigating cable length errors at the mid-span access location in a pre-engineered fiber optic communications network. At least one optical fiber of the distribution cable is accessed at the mid-span access location and optically connected to an optical fiber disposed within the tether. Preferably, the first end of the tether is attached to the distribution cable by overmolding the mid-span access location with a flexible encapsulant material. The end of the optical fiber of the tether may be splice-ready or connectorized at the second end of the tether and protected within a crush resistant tube. Alternatively, the second end of the tether may terminate in an optical connection terminal defining at least one optical connection node, or may terminate in a linear chain of articulated optical connection nodes.

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 factory-prepared preterminated and pre-connectorized fiber optic distribution cable having at least one mid-span access location for providing access to a plurality of preterminated optical fibers pre-connectorized with a multi-fiber connector is provided. Also provided is a method of forming a pre-connectorized fiber optic distribution cable by terminating and pre-connectorizing a predetermined number of the plurality of optical fibers of the cable to create a pre-connectorized mid-span access location. The fiber optic distribution cable provides a low profile mid-span access location that is sufficiently flexible to be installed through relatively small-diameter buried conduits and over aerial installation sheave wheels and pulleys without violating the minimum bend radius of the cable or the optical fibers. A protective encapsulant protects and seals the mid-span access location during cable reeling, unreeling, installation and until the access location is needed for interconnecting a connectorized fiber optic drop or branch cable.

摘要： An overmolded multi-port optical connection terminal for a fiber optic distribution cable includes a tether cable containing a plurality of optical fibers optically connected to a corresponding plurality of optical fibers terminated from the fiber optic distribution cable at a first end of the tether cable, an overmolded housing a the second end of the tether cable, at least one connector port, and plenum means for accommodating excess fiber length (EFL) caused by shrinkage of the tether cable and/or pistoning of the optical fibers of the tether cable during connector mating. In one embodiment, a centralized plenum means is defined by an internal cavity within the overmolded housing sufficient for accommodating the EFL without micro bending. In another embodiment, a distributed plenum means is defined by an oversized tubular portion of the tether cable having an inner diameter sufficient for accommodating the EFL without micro bending.

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.
