摘要:
A multi-fiber fiber optic ferrule comprising a ferrule body, at least one optically functional optical fiber received within at least one optical fiber bore defined by the ferrule body, and at least one optically non-functional guard fiber received within at least one guard fiber bore defined by the ferrule body. A multi-fiber ferrule defining at least one optical fiber bore opening through a front face, at least one optically functional optical fiber received within the ferrule and maintained within the at least one optical fiber bore, at least one guard fiber bore opening through the front face, and at least one optically non-functional guard fiber received within the at least one guard fiber bore.
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.

A pulling grip includes a pulling grip sleeve, a pulling grip housing and a furcation plug attached to the terminated end of a fiber optic cable. The pulling sleeve includes a bag adapted to be positioned over the pulling grip housing and the furcation plug and to be opened and closed by a lengthwise extending zipper. The pulling grip housing has a first compartment defining an elongate channel for routing optical fibers of the fiber optic cable and a second compartment defining a plurality of pockets that each store a plurality of fiber optic connectors mounted upon the ends of the optical fibers. The pulling grip housing may be formed as a plurality of injection molded modules to increase rigidity and to reduce manufacturing cost. The furcation plug includes means for readily integrating the furcation plug with a conventional distribution frame or rack, or with a cross-connect housing.

A factory prepared fiber optic distribution cable has at least one predetermined access location for providing access to at least one pre-connectorized optical fiber. The fiber optic distribution cable includes at least one preterminated optical fiber withdrawn from a tubular body at the access location, a connector attached to the preterminated optical fiber, a transition piece for transitioning the preterminated optical fiber from the tubular body into a protective tube, and a protective shell encapsulating the access location for protecting the pre-connectorized optical fiber. Alternatively, the fiber optic distribution cable includes at least one preterminated optical fiber withdrawn from a tubular body, a transition piece for transitioning the preterminated optical fiber from the tubular body into a protective tube, a connector attached to the preterminated optical fiber, a plurality of cable centralizers, and a protective shell for encapsulating the access location and protecting the pre-connectorized optical fiber.

A method of mid-span accessing at least one optical fiber from a fiber optic distribution cable. A buffer tube transition piece operable for transitioning a plurality of preterminated optical fibers from a buffer tube into protective tubing.
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.

A connector housing for a communications network includes a housing assembly having a front panel, a rear panel, a first side panel, a second side panel, a bottom panel, and a top panel. In one configuration, the connector housing includes a jumper management panel that is rotatable into at least two different positions relative to the top panel of the housing assembly. In another configuration, the connector housing has a splice shelf assembly. The splice shelf assembly is attached to the housing assembly and rotatable about a vertical axis relative to the housing assembly. Another configuration of the connector housing has at least one cable entry plate that is removably attached to a side panel of the housing assembly. Additionally, one strain relief assembly has a furcation plug of a cable assembly that is attachable to a mounting rail for securing the same.

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.
