Disclosed herein are cable sealing devices having features for enhancing effective sealing, volume compensation, seal pressurization, cable size range-taking, cable installation and insert installation. Also disclosed herein is an enclosure including at least one cable sealing device.

A multiport assembly including one or more optical adapters configured to receive an optical connector, a shell having a front face defining one or more connection port insert openings extending from an outer surface of the front face into a cavity of the shell, a connection port insert positioned at least partially within the one of the connection port insert openings of the shell, the connection port insert defining a body including an optical connector opening extending from a front end of the body to a rear end of the body, and a sealing member disposed between the connection port insert and the shell.

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.

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.

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.

A system includes a housing (105) that includes one or more ports (113) through which electrical connections to one or more electronic components situated within the housing can be made from exterior of the housing. At least one enclosure bushing (204) is coupled to at least one port. The enclosure bushing includes a cylindrical service jacket receiver (207) defining a lumen (208), a flange (212) abutting a portion of the housing, and one or more lugs (216,217,302,303) extending from a portion of the cylindrical service jacket receiver. A coupling nut (205) having one or more circumferential lug receivers (702,703,704,805) applies a compression force to the frustoconical weather gasket when the one or more lugs engaging the locking notch (708) of the one or more circumferential lug receivers.

An enclosure for spliced cables includes an outer housing, a splice tray, internal circuitry, a first fiber and a cable stub. The splice tray and the internal circuitry are positioned inside the outer housing. The first fiber may be connected to the internal circuitry. The cable stub includes a second fiber spliced to the first fiber to form a splice. The splice is configured to be positioned on the splice tray so as to protect and support the splice. The internal circuitry includes a downstream monitor channel fiber, an upstream monitor channel fiber, a downstream channel fiber, and an upstream channel fiber.

A sealed structure (e.g., sealing module, sealing projection, etc.) transitions the direction of one or more cables passing through the structure. Sealant (e.g., a gel block) is disposed within the structure to seal one or more cables extending along a transition path within the sealed structure. Ducts and/or cables may be anchored to the sealed structure. The sealed structure may be mechanically secured to a closure at a selected rotational orientation.
