Aspects of the present disclosure relates to a sealing unit for sealing an optical fiber cable. The sealing unit can include a body member that defines a passage that extends lengthwise therethrough, and a first cavity adjacent a proximal end where the first cavity has a first diameter and a second cavity adjacent a distal end where the second cavity has a second diameter. A sealing member that has a distal end face and a proximal end face, The sealing member can be mounted within the first cavity of the body member and configured to create a seal about the optical fiber cable when the optical fiber cable is routed therethrough. When in use, a duct can be rotated inside the second cavity of the body member such that internal threads of the second cavity cut into the duct to drive the duct forward to abut the distal end face of the sealing member to prevent a leak path.

Fiber management assemblies for telecommunications closures. The assembly includes a frame adapted to conform to the wall of a housing piece of a closure. A fiber management tray is pivotally coupled to the frame. The frame supports the tray and spaces the tray away from fiber optic connectors positioned in connector ports defined by the closure. In addition, the pivotability of the tray relative to the frame can provide access to the connectors and/or connector ports without disrupting fiber management on the tray itself.

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 butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, and a second gel. The butt closure base further includes a plurality of cable entry passages, each of the plurality of cable entry passages defined between one of the plurality of cavities and one of the plurality of wedge assemblies. The butt closure base further includes a plurality of bushings, each of the plurality of bushings disposed in one of the plurality of cable entry passages.

Aspects and techniques of the present disclosure relate to a cable sealing structure comprising a cable sealing body including a gel and methods of making anisotropic behavior in cable sealing structures made with a dry silicone gel. In one aspect, various three-dimensional printing techniques are used to make a cable sealing structure that includes a gel. The cable sealing body has a construction that elastically deforms to apply an elastic spring load to the gel. The cable sealing body has a construction with anisotropic deformation characteristics that allows the cable sealing body to be less deformable in one direction than in others. The cable sealing structure can be utilized to seal fiber optic cables more uniformly while limiting the potential of leakage.

A seal may include a first seal section defining a first internal cylindrical surface defining a first internal diameter configured to provide a substantially fluid-resistant seal between the first internal cylindrical surface and an external surface of a cable. The seal may also include a second seal section coupled to the first seal section and defining a second internal cylindrical surface defining a second internal diameter configured to provide a substantially fluid-resistant seal between the second internal cylindrical surface and an external surface of a cable, wherein the first internal diameter and the second internal diameter may differ from one another. An entry module assembly for facilitating entry of one or more cables into an enclosure may include an entry module plate defining an aperture configured to receive a cable therethrough, and a seal coupled to the entry module plate and extending through the aperture of the entry module plate.

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.

A sealed terminal has a housing, a cover, a splice tray, an adapter plate, and a splice chip. The cover is connected to the housing to close an interior compartment and has input ports for receiving one or more cables and an output adapter module having a plurality of distribution ports. The splice tray is positioned in the interior compartment and has one or more cable retainers configured to route the one or more cables within the interior compartment. The adapter plate is connected to the splice tray and has a plurality of adapters for connecting the one or more cables to the distribution ports. The splice chip is connected to the splice tray and has a plurality of slots for receiving and routing the one or more cables. The housing includes a radiused wall for routing the cables within the interior compartment without bending the cables.

A clamp assembly includes a first clamp half-piece and a second clamp half-piece. In one example, the clamp half-pieces are identically shaped. In one example, each of the clamp half-pieces has at least one integral pin and at least one aperture. The first and second clamp half-pieces are pivotally connected to each other via a first snap-fit interface in which the integral pin of the first clamp half-piece snap-fits into the at least one aperture of the second clamp half-piece. The clamp assembly can also include a link arm connected to the first clamp half-piece via a second snap-fit interface. A lever arm can also be included that is pivotally connected to the link arm via a third snap-fit interface. The clamp assembly does not require separate link pins or other parts and only includes four components: the clamp half-pieces, the link arm, and the lever arm.
