A multi-purpose sealing device is described herein for use in a port structure of fiber terminal, telecommunication enclosure; or a bulkhead. The exemplary sealing device has a body having an open end and a closed end, wherein the closed end includes a removable portion and a pulling device to facilitate removal of the exemplary sealing device from a port structure. In one aspect, the exemplary sealing device is a single part made of a resilient material, while an alternative aspect, the exemplary sealing device includes a rigid connection portion disposed within the open end of the body. The exemplary device can be used as a dust cap or plug prior to making a service connection and/or it can be used as a port/cable sealing device after the service connection is made.

A fiber distribution device includes a swing frame chassis pivotally mounted to a support structure. At least a first optical splitter module is mounted to the swing frame chassis. Pigtails having connectorized ends are carried by the swing frame chassis and have portions that are routed generally vertically on the swing frame chassis. An optical termination field includes fiber optic adapters carried by the swing frame chassis. The fiber optic adapters are configured to receive the connectorized ends of the pigtails.

Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.

A cable management unit including a support assembly for mounting a patch panel, such as to a wall. The support assembly may include first and second anchor members adapted to be anchored to the wall, and first and second support arms hingedly coupled to the first and second anchor members at first and second hinge points, respectively. The first and second support arms may be adapted to be coupled to the patch panel. A chassis the patch panel may be supported by the first and second support arms. The first and second support arms may be configured to pivot about the first and second hinge points respectively between storage and access positions. The first and second support arms may extend outward from the wall in the access position and may be substantially parallel to the wall in the storage position.

A connector pack for an optical fiber enclosure has a plurality of connector slots each for receiving a respective connector on a cable. The connector pack has a first set of connector slots on a first side of a connector pack body and a second set of connector slots on a second side of the connector pack body. The first set of connector slots and the second set of connector slots each include a latch opening for receiving a latch of a respective connector. The latch opening of the first set of connector slots is offset with respect to the latch opening of the second set of connectors. According to some embodiments, the latch opening of the first set of connector slots is inverted with respect to the latch opening of the second set of connector slots.

A fiber optic cable transition assembly for transitioning a plurality of optical fibers from a multi-fiber cable to a plurality of furcation tubes. The fiber optic transition assembly has a housing with a front opening and an internal passageway that is defined by a wall and a narrow region. The housing is adapted to receive epoxy adhesive. The fiber optic transition assembly has a boot that is positioned at least partially inside the housing for receiving the multi-fiber cable to provide strain relief to the plurality of optical fibers extending therethrough. The fiber optic transition assembly has a plug supported by the boot and retained by the housing to prevent epoxy adhesive from entering the multi-fiber cable.

An interconnect system is provided that involves pre-installing a connector housing an optical connector in an adapter and a ferrule of the same optical connector on a cable. The ferrule terminates one or more groups of optical fibers, and a ferrule push component is also pre-installed on the same group(s) of optical fibers. The connector housing is configured to receive and retain the ferrule and ferrule push component without being removed from the adapter to simultaneously form the optical connector and install the optical connector in the adapter. Embodiments such an interconnect system involving high fiber-count cables and related installation methods involving many optical connections are disclosed.

A pre-terminated end of a fiber optic cable has a protective cap that protects the optical fiber and the ferrule assembly at the terminal end. The protective cap has an attachment feature enabling a pull cord to attach to the protective cap. The protective cap has a body including an exterior surface and a receptacle formed in the body and configured to receive a portion of the fiber optic cable, and the attachment feature. The attachment feature includes a cavity formed in a tip of the body and at least two openings formed in the exterior surface of the body and connected to the cavity.

Embodiments of a bundled optical fiber cable are provided. Included therein is a central cable unit spanning a first length from a first end to a second end. The central cable unit has a first plurality of optical fibers disposed within a cable jacket. The bundled optical fiber cable also includes at least one optical fiber drop cable wound around the cable jacket of the central cable unit. Each optical fiber drop cable spans a second length from a first end to a second end. Further, each optical fiber drop cable includes one or more optical fibers disposed within a buffer tube. The first end of each optical fiber drop cable is substantially coterminal with the first end of the central cable unit, and the first length spanned by the central cable unit is longer than the second length spanned by each of the optical fiber drop cables.

Devices, systems, and methods for extending an optical distribution network to an end point in a user's premises over a power line drop cable that supplies metered power to the premises are disclosed. An existing power line drop cable to the premises serves as an intermediate medium to transmit high-bandwidth data from an optical distribution network to a transceiver in a user's premises. Fiber from an optical distribution network connects to an outside-plant optical-to-electronic device comprising at least an optical network unit and a domain master. The device is powered by electricity from the electrical network to which the first power line drop cable is attached. The device can have an electromagnetic-interference filter.
