A cam-based, force-controlled system for seal activation includes a plurality of sealing segment assemblies. Each sealing segment assemblies includes an inner segment and an outer segment assembly configured to mate with the inner segment. The inner segment includes an upper segment portion, a lower segment portion, and an inner segment seal disposed between the upper segment portion and the lower segment portion. The outer segment assembly includes an upper segment element, and outer perimeter element, an outer segment seal disposed between the upper segment element and the outer perimeter seal, a rod coupled to the upper segment element, a first cam coupled to the upper segment element, a second cam coupled to the upper segment element, and a handle coupled to the rod, the first cam, and the second cam.

Cam-based force-controlled system for seal activation

A sealing system for a telecommunication closure includes an endcap having a plurality of slotted areas defined therein; and a plurality of sealing segment assemblies mounted to the endcap that when combined form a substantially continuous sealing perimeter around the endcap. Each sealing segment assembly is disposed in one of the plurality of slotted areas and includes an inner segment and an outer segment that when mated together are configured to seal at least one cable routed through a cable port opening.

Sealing system for telecommunication closures

A fiber optic assembly is provided including a cable port seal including a first sealing component, a first and second compression element configured to compress the first sealing component in a first direction, a second sealing component, and a cap configured to compress the first and second sealing component in a second direction. The compression in the first direction and second direction provides a seal around a cable. The fiber optic assembly also includes a strain relief including a body defining a sidewall, a passthrough disposed in the body from a first end to a second end, and a slot enabling a fiber optic cable to be inserted into the passthrough. The strain relief also includes a plurality of hooks disposed on an exterior surface of the sidewall and configured to resist movement of a strength member of the cable, when the strength member is wrapped around the body.

Cable seal and strain relief assembly

A fiber optic assembly is provided including a housing having an exterior and an internal volume, a cable port configured for a plurality of fiber optic cables to pass from the exterior to the internal volume of the housing, and a cable strain relief. The cable strain relief includes a base and a restraint projection extending from the base. The restraint projection includes opposing first second faces, a leading edge facing the internal volume, and a trailing edge facing the exterior. The restraint projection is configured to receive the plurality of fiber optic cables banded at a first location disposed at the leading edge and a second location disposed at the trailing edge, such that a portion of the plurality of fiber optic cables is disposed at the first and second faces, and the restraint projection resists lateral movement of the plurality of fiber optic cables relative to the base.

A cable strain relief for a fiber optic assembly is provided including a body defining a sidewall, a cable passthrough disposed in the body from a first end of the body to a second end of the body, and a cable slot disposed through sidewall enabling a fiber optic cable to be inserted into the cable passthrough. The cable strain relief also includes a plurality of hooks disposed on an exterior surface of the sidewall. The plurality of hooks are configured to resist movement of a strength member of the fiber optic cable, when the strength member is wrapped around the body.

The present disclosure relates to a process by which an optical fiber drop cable is created and routed in a multiple dwelling unit ('MDU'). The optical fiber drop cable is formed with a feeding tool, and the optical fiber drop cable includes a tube having optical fibers enclosed within the tube. The feeding tool creates a slit within the tube through which optical fibers are fed and thereby inserted into the tube along the tube's length. Once the tube exits the feeding tool with the optical fibers enclosed (thereby forming the optical fiber drop cable), the optical fiber drop cable is then routed into an individual dwelling unit of the MDU by a transition assembly including a transition plug and a routing plug that leads an optical fiber from an exterior of the individual dwelling unit to a subscriber termination point in an interior of the individual dwelling unit.
