    Abstract: A fiber fanout assembly is provided with one or more endcaps, an epoxy fill hole, and air vent holes. A mold can be used with endcaps to create an epoxy body without an external housing structure. External housing structures can also be provided with one or more endcaps. Air vent holes can be provided in the endcaps. An epoxy fill hole can be provided in an endcap. An epoxy fill hole can also be provided adjacent to a fiber breakout end of the fiber fanout housing.

    Abstract: A factory processed fiber optic ferrule assembly and field installable cable system are configured to pass through tight, microducts when routed to a demarcation point. A connector housing attaches to the fiber optic ferrule assembly at the demarcation point (or after leaving the tight, microducts) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

    Abstract: A connection system includes an optical connector assembly; and an optical plug. The connector assembly includes a stack of gel-groove assemblies and a spring assembly mounted within a housing. Each of the gel-groove assemblies includes a first gel block at a first axial end, a second gel block at a second axial end, and a fiber mating region between the first and second gel blocks. The optical plug including sub-modules over-molded over arrays (e.g., ribbons) of the optical fibers. Each sub-module defines notches for receiving latches of the spring assembly when the optical plug is coupled to the first axial end of the optical adapter. Bare optical fibers extend from the plug, pass through the first axial gel block, and enter the fiber mating region when the plug is coupled to the adapter.

    Abstract: The present disclosure relates to a field installable connector system. The connector system includes a factory terminated subassembly including a ferrule terminating an optical fiber of an optical fiber cable. The factory terminated subassembly has a small transverse cross-section to facilitate routing through a duct. The connector system also includes a field installable subassembly including various connector components that can be installed after the factory terminated subassembly has been routed through a duct. The components can be sealed and hardened.

    Abstract: A fiber optic telecommunications device includes a frame defining a right vertical support and a left vertical support. A chassis is mounted to the right and left vertical supports, wherein the chassis is configured to pivot about a pivot axis that is defined by one of the right and left vertical supports. A plurality of modules are mounted on the chassis, each of the modules slidable on the chassis along a direction extending between the right and left vertical supports, wherein the chassis is configured to pivot about a plane parallel to the sliding direction of the modules, each module defining fiber optic connection locations.

    Abstract: A fiber optic alignment device includes a first and a second alignment block and a first and a second gel block. A fiber passage extends from a first end to a second end of the fiber optic alignment device. The fiber passage is adapted to receive a first optical fiber through the first end and a second optical fiber through the second end. An intermediate portion of the fiber passage is positioned between the first and the second ends. The intermediate portion is adapted to align the first and the second optical fibers between the first and the second alignment blocks. A first portion of the fiber passage is positioned between the first end and the intermediate portion of the fiber passage. The first portion extends between the first alignment block and the first gel block. A second portion of the fiber passage is positioned between the second end and the intermediate portion of the fiber passage. The second portion extends between the second alignment block and the second gel block. End portions of the first and the second optical fibers may be cleaned when slid between the alignment blocks and the gel blocks. The fiber passage may include an undulating portion.
