A sealed terminal has a housing, a splice tray, and a faceplate. The housing has an interior compartment and a first perimeter flange defining an opening into the interior compartment. The splice tray is positioned in the interior compartment and is configured to support a module or a cartridge. The faceplate has a plurality of ports and a second perimeter flange extending at a perimeter edge of the faceplate. The sealed terminal also has at least one connection bracket and a gasket for connecting the housing and the faceplate to each other. The connection bracket has a slot receiving the first perimeter flange and the second flange in an abutting position. The gasket is positioned between the first perimeter flange and the second perimeter flange and configured to seal any gap therebetween.

Aspects of the present disclosure relate to a modular fiber optic distribution system for enhancing installation flexibility and for facilitating adding components to a terminal housing over time so as to delay cost. The system is configured to allow components (e.g., inserts, add-on modules, etc.) to be readily added to the terminal housing over time to expand capacity, provide upgrades and to provide forward and backward compatibility.

Devices such as multiports comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and is biased by a resilient member.

Fiber optic splice closures adapted to house a large number of fiber splices. The closure holds a splice assembly including a support frame that supports two stacks of splice trays. The splice assembly can be inverted to access the second stack of splice trays. The support frame can also define one or more fiber organizing areas within the splice closure.

An optical fiber junction assembly and a sealing method thereof, and an optical fiber junction box, where in the optical fiber junction assembly, a first housing has first mating surface and an accommodating cavity, a first welding bump is disposed on the first mating surface, and is disposed around an opening of the accommodating cavity, a second welding bump is disposed on the second mating surface, the first welding bump and the second welding bump are configured to form colloid after being heated and melted, and connect and seal the first mating surface and the second mating surface, and an overflow groove is disposed on at least one of the first mating surface and the second mating surface, and is configured to accommodate the colloid.

The present disclosure relates to a re-enterable enclosure for a fiber optic network. The enclosure can include features such as a low compression-force perimeter gasket, cable seals constructed to seal effectively seal triple points, multi-function port size reducer plugs and multi-function blind plugs.

Aspects of the present disclosure relate to structures and designs that allow gels to be used to conform freely to optical cables while simultaneously minimizing the displacement of the gel due to deformation forces acting on the gel.

A gel sealing device includes a gel sealing block (5) which provides a sealing section (22) through which the elongate parts (13, 14) extend. The gel sealing block (5) includes an upper flange (11) and a lower flange (12) with a support section (11a, 12a, 12b) disposed therebetween. The upper and lower flanges (11, 12) sandwiches, in direction of extension of the elongate parts (13, 14), a gel inner ring (7) supported by said support section (2) and a gel outer ring (6, 10a) covering the gel inner ring (7) in a radial direction extending transverse to said extension direction. The gel inner ring (7) and the gel outer ring (6, 10a) are made of a gel sealing material.

A sealing unit (28) that fits within the sealing unit opening (26) of a housing 22. The sealing unit (28) including a sealant arrangement (32) that define a plurality of cable ports (30). The sealing arrangement is also configured for providing a peripheral seal between the housing (22) and the sealing unit (28). The sealing unit (28) includes an actuation arrangement (31) for pressurizing the sealant arrangement (32) within the sealing unit opening (26). The sealant arrangement (32) includes a plurality of sealing modules (33a-33e) each sized to form only a portion of the pressure actuated sealant arrangement (32).
