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: 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 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 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.
