A multi-port optical connection terminal for use as a branch point in a fiber optic communications network at a distance from a mid-span access location provided on a distribution cable having a plurality of optical fibers. The multi-port terminal includes a base and a cover affixed to the base. A stub cable port formed through one of the base and the cover receives a stub cable having at least one optical fiber extending continuously from the multi-port terminal to the mid-span access location. A first end of the optical fiber is optically connected to a respective optical fiber of the distribution cable at the mid-span access location and a fiber optic connector is mounted upon the second end. At least one connector port is provided on the multi-port terminal for receiving the fiber optic connector and a connectorized end of a fiber optic drop cable extending from the multi-port terminal.

Multi-port optical connection terminal

An outdoor cabinet interconnects an optical fiber of a feeder cable with at least two optical fibers of a distribution cable at a local convergence point in an optical network. The cabinet defines an interior compartment comprising a feeder cable side having a feeder cable entry port and a feeder cable slack storage area, a distribution cable side having a distribution cable entry port and a distribution cable slack storage area, at least one splice tray and at least one coupler module. A feeder pigtail is routed from the splice tray and connected to an adapter provided on the coupler module. At least two distribution pigtails are routed from the splice tray and connected to adapters provided on the coupler module. The coupler module splits an optical signal carried on the optical fiber of the feeder cable into optical signals carried on the optical fibers of the distribution cable.

Local convergence cabinet

A closure interconnects at least one optical fiber of a feeder cable with two or more optical fibers of a distribution cable at a local convergence point in an optical network. The base of the closure defines a fiber storage and fiber management area adjacent one of the end caps and a fiber coupling area adjacent the other end cap. The fiber coupling area includes one or more coupler modules for splitting an optical signal carried on the optical fiber of the feeder cable into different optical signals carried on the two or more optical fibers of the distribution cable. The optical fiber of the feeder cable is spliced to an input optical fiber of a connectorized pigtail and then split into two or more output optical fibers of connectorized pigtails. The output optical fibers of the pigtails are then spliced to optical fibers of the distribution cable.

Aerial closure for local convergence point

A fiber optic NID includes a base defining an interior cavity and a protective cover. A backplate shaped, sized, and configured to be positioned within the internal cavity defines a first fiber management area, a second fiber management area, and a fiber connecting area. The fiber connecting area includes a raised platform having a connection tray, an adapter, and a routing guide positioned on the platform and secured thereto. The connection tray optically joins an optical fiber of a feeder cable from the first fiber management area to a first connector and an optical fiber of a distribution cable from the second fiber management area to a second connector. The first connector and the second connector are routed along the routing guide to the adapter and optically joined to connect the optical fiber of the feeder cable and the optical fiber of the distribution cable.

Fiber optic network interface device

A cable breakaway assembly is adapted for mounting within a stationary component of a communications service network to prevent damage to a feeder cable in the event that an excessive pulling force is applied to a customer cable spliced to the feeder cable. In one embodiment, the cable breakaway assembly comprises a generally symmetric base, at least one cutting blade fixed to the base, and a swing arm rotatably attached to the base and movable between an extended position and a retracted position. The communications cable is secured to the swing arm by a cable clamp and the swing arm is biased in the extended position by a torsion spring. When the excessive force is applied to the customer cable the swing arm rotates to the retracted position, thereby bringing the communications cable into contact with the cutting blade and severing the communications cable. In another embodiment, the base defines a cavity and the swing arm is replaced by a cable block resiliently positioned within the cavity. The cable block is biased in the extended position by at least one linear coil spring positioned within the fig cavity between the cable block and the base.

Cable breakaway assembly

A splice closure contains multiple splice trays that can be individually pivoted and accessed so that the splice closure is capable of optimally carrying and providing access to numerous optical fibers and optical fiber splices. The splice closure has a housing defining an internal cavity and at least one opening to the internal cavity. An end cap is capable of occluding the opening of the housing to provide an enclosed configuration. A support frame has opposite front and rear ends, the front end of the support frame is connected to the end cap, and the support frame is capable of being positioned within the internal cavity of the housing during the enclosed configuration. The support frame extends in a longitudinal direction between the front and rear ends, and defines a frame axis that extends in the longitudinal direction. The multiple splice trays are pivotally carried by the support frame so that there are a plurality of axes of rotation that are generally parallel to the frame axis and about which the splice trays are respectively pivotable. Biasing mechanisms are operative for releasably holding the splice trays to the support frame.

Splice closure with removable and pivotable splice trays, and associated methods

A splice closure has a frame with an end cap on one end, the end cap having apertures for the passage of express cables and drop cables. Coupler cassettes are carried by the frame in a coupler cassette subassembly. Each coupler cassette houses a plurality of couplers. The coupler cassettes are interconnected such that a single input optical fiber entering the coupler cassette subassembly results in multiple output optical fibers leaving the coupler cassette subassembly. A splice organizer comprising a plurality of splice holders is carried by the frame exterior and adjacent to the coupler cassette subassembly for retaining splices to and from the coupler cassettes. A housing encloses the frame, coupler cassette subassembly and splice organizer. An optical fiber storage tray is located adjacent the splice organizer for storing any excess express or drop cable optical fibers that are not spliced to any of the output optical fibers of the coupler cassette subassembly.

Fiber optic closure with couplers and splice tray

A housing defines an internal cavity and an opening to the internal cavity. An end cap occludes the opening. Fiber optic cables extend through ports in the end cap. A support frame is connected to the end cap and is positioned in the internal cavity. The support frame includes a support member having opposite front and rear ends. The support frame includes upper and lower front extensions connected to the support member. The front extensions extend away from the support member and divergently with respect to one another. The front extensions are connected to the end cap. Flanges protruding from the front extensions receive strain relief for brackets. Container-like devices for containing optical fibers are carried by opposite sides of the support member. An elongate channel for receiving optical fibers and an elongate opening to the channel extend along the back side of a container-like device carried by the support member. A transition plate is mounted to the top of a container-like device carried by the support member. The transition plate includes protrusion that define aperture for receiving ties that hold optical fibers. An adjustment bracket is mounted in movable relation to the support member and is movable toward and away from a container-like device carried by the support member. The support frame further includes upper and lower rear extensions connected to and extending forwardly and divergently from the rear end of the support member.

Optical fiber interconnection closures

A closure arrangement for cable splice assemblies having two hinged cover members. The cover members are independently hingedly secured to a central spine. The spine, in turn, is affixed to a portion of the frame of the splice assembly. In operation, the cover members are opened outwardly to expose virtually all of the outer portion of the internal splice components. In the described embodiment, the cover members are secured to one another by clasp or buckle-type closures that engage complimentary tabs.

Splice closure

A closure that is operative for containing optical fiber splices includes a support assembly that supports the splices. While the closure is in an enclosed configuration, the support assembly and a holding bracket are substantially contained in a housing of the closure. When the splices within the closure are to be serviced, the support assembly and the holding bracket are removed from the housing. Thereafter, the holding bracket is configured so a protruding portion of the holding bracket extends away from the support assembly to provide an extended configuration. While in the extended configuration, the protruding portion of the holding bracket is clamped to a work surface with a clamping device so the holding bracket supports the support assembly in a cantilever-like fashion and the holding bracket and the clamping device do not substantially interfere with the servicing of the optical fiber splices. After servicing the splices, the holding bracket is configured in an unextended configuration and the support assembly, with the holding bracket attached thereto, is returned to the housing, so the holding bracket is readily available for use the next time the closure is serviced.
