    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 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: A connector housing includes a housing assembly and a tray assembly. The tray assembly being slidably mounted relative to the housing assembly and having a first position within the housing assembly so that the tray assembly is fully inserted within the housing assembly in a stored position. The tray assembly also has a first position beyond an interior of the housing assembly. In the first position, a first portion of a tray of the tray assembly is rotatable relative to a second portion of the tray at a hingeable section of the tray, thereby allowing easier access to components, connections, and/or cables on the tray. In another embodiment, the tray assembly is slidable into a rearward position beyond the interior of the housing assembly.
