The tray may include a combination of a fiber storage device, a fiber splice device, and a fiber termination device, which are arranged in a particular order. Alternatively, the tray may include a plurality of fiber termination devices. Further, the tray may include a fiber funneling structure that make is easy to route and retain fibers in the tray.
Abstract:
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.
Abstract:
A sealing block assembly (110) protects telecommunications equipment from water and dust. The sealing block assembly (110) is disposed around a telecommunications cable (112), and the sealing block assembly (110) includes a housing (118, 218). The housing (118, 218) includes a first end (130, 230) and a second end (132, 232), the second end (132, 232) includes a plurality of movable fingers (128, 228). The sealing block assembly (110) also includes a seal (121) disposed within the housing (118, 218) between the movable fingers (128, 228) and the telecommunications cable (112). Further, the sealing block assembly (110) includes a clamp (122) disposed around the movable fingers (128, 228) of the housing (118, 218). The clamp (122) is configured to compress the movable fingers (128, 228) and the seal (121).

Abstract:
An enclosure (10) includes a base (38) defining a splice region (148) and a cover (40) coupled to the base (38) to move between a closed position and an open position. A plurality of ruggedized adapters (26) are on the cover (40), each adapter having an inner port (64) and an outer port (66). A removable module (32) is disposed on the cover (40), at least one input fiber (12) being routed from the splice region (148) of the base (38) to the removable module (32), wherein the at least one input fiber (12) is output from the module as a pigtail (28) having a connectorized end that is connected to an inner port (64) of a ruggedized adapter (26). A cable input location (16) receives an input cable (14/20) including at least one tube (138) surrounding at least one fiber (12) that carries the same signal as the at least one input fiber (12) being routed from the splice region (148) to the removable module (32). The input cable (14/20) is anchored to the base (38) at the cable input location (16). A tube holder (150) is slidably mounted to the base (38) past the cable input location (16), wherein the tube holder (150) keeps separate an unused fiber-carrying tube (138) that is stored within the base (38) in a loop (122) from a fiber- carrying tube (138) whose fiber (12) leads toward the splice region (148) of the base (38) for further routing toward the removable module (32).
Abstract:
The present disclosure provides a system and method for sealing cable ports (10) of a telecommunications box (14). The system and method enables quick and easy sealing of cables of a variety of outer diameters. In one embodiment of the present disclosure the port (10) of the telecommunications box includes a port reducer (16) that includes a pair of internal gel strips (22, 24) that when compressed deform, and together form a gel ring (36) that provides a seal between the external surface of the cable and the inside of the port reducer.
Abstract:
A seal (110) for a telecommunications enclosure (100) includes a first body (114) made of a first material. The first body (114) defines a port (112) and the port (112) defines a port axis (113). The first body (114) further includes a first axial face (122), an opposite second axial face (124), and a peripheral surface (126). The peripheral surface (126) surrounds the first body (114) between the first axial face (122) and second axial face (124), and the peripheral surface (126) further surrounds the port. The seal (110) also includes a second body (116) made of a second material. The second body (116) is disposed on at least the peripheral surface (126) of the first body (114). The second material is softer than the first material of the first body (114).
Abstract:
A fiber optic adapter assembly closure for optically and mechanically coupling two fiber optic connectors. The closure includes a first adapter half with a connector port end positioned opposite from an engagement end. The connector port end defines a connector port and the engagement end includes an engagement flange. The closure also includes a second adapter half with a connector port end positioned opposite from an engagement end. The connector port end defines a connector port and the engagement end includes an engagement flange. The engagement flange of the first adapter half is configured to mate with the engagement flange of the second adapter half. The closure also includes a coupler that mounts over the mated engagement flanges of the first and second adapter halves to secure the engagement ends of the first and second adapter halves together.
