摘要:
A sealing device (100) for sealing a duct (10) with inner tubes (14) to an enclosure (16) includes a housing (40, 440) having a body (102) defining a tubular shape extending between a first end (104, 442) and a second end (106, 444). Snaps (42, 446) at the first end (104, 442) snap at the housing (40, 440) to a telecommunications port (18). Tabs (110) at the second end (106, 444) engage corrugations (12) on a duct (10) mounted to the second end (106, 444) of the housing (40, 440). The housing (40, 440) receives tubes (14), such as blown fiber tubes for receipt of fibers during blown fiber installation processes. The housing (40, 440) defines a chamber (28) for receiving resin which seals around the tubes (14). Once the resin hardens, the snaps (42, 441) can no longer be moved, thereby preventing the housing (40, 440) from being removed from the telecommunications device. A lower tube holder (30, 430) is provided for organizing the tubes (14) adjacent to the second end (106, 444) of the housing (40, 440). An upper tube holder (50, 350, 450) is provided for organizing the tubes (14) adjacent to the first end (104, 442) of the housing (40, 440). The upper tube holder (50, 350, 450) defines a center passage (320) for receipt of poured resin. ( FIG. 2 )

摘要:
A fiber management tray (20) is disclosed. The fiber management tray (20) includes a tray body (22) defining a fiber storage region (24) for storing excess optical fiber length (26). The tray body (22) also includes a splice mount (28) for mounting at least one optical splice (30). The fiber management tray (20) includes a restricted access region (32) and an unrestricted access region (34) on the tray body (22). The splice mount (28) and the fiber storage region (24) are provided at the unrestricted access region (34), and an optical splitter component (36) is provided at the restricted access region (32).
摘要:
A telecommunications port including a port (20, 120) includes a port body (30, 130) having a circular end (42, 142) and a tear-off tap (24, 124) positioned on the circular end (42, 142). A webbing (52, 152) seals the tap (24, 124) to the circular end (42, 142). The tap (24, 124) includes a tap body (50, 150) including a projecting handle (60, 160) and a reinforcement element (68). In one embodiment, the reinforcement element (68) includes a spherically shaped middle body portion (70). A further embodiment of a reinforcement element (68) includes a tapering circular rib (80) extending around the periphery of the tap body (50) from the handle (60) to an opposite side (82) of the tap body (50). A further embodiment of a reinforcement element (68) includes a linear rib (190) positioned on an inside surface of the tap body (150). A gap (92, 192) is provided inside port (20, 120) to promote removal of the tap (24, 124). A method of use includes accessing a port (20, 120) by providing a tear-off tap (24, 124) attached to a circular end (42, 142) of a port body (30, 130) with a webbing (52, 152), gripping a projecting handle (60, 160), and pulling the handle (60, 160) to tear the webbing (52, 152) to form a circular opening, wherein a reinforcement element (68) prevents breakage of the tap body (50, 150).
摘要:
Optical fiber cables (180) are installed at an enclosure defining at least one cable port (109) by loading a seal block assembly (120, 140, 220, 340) onto each optical fiber cable (180); installing and/or connecting a fixation assembly (160, 460) onto each optical fiber cable (180); and latching the seal block assembly (120, 140, 220, 340) to the enclosure. The cable (180) is secured by the fixation assembly (160, 460). The fixation assembly (160, 460) retains one or more types of strength members (182, 183) of the optical fiber cable (180). The seal block assembly (120, 140, 220, 340) snaps and/or clips into a locked position relative to the enclosure. A filler rod (502) can be used to fill an unused port in the seal block assembly (120, 140, 220, 340). An attachment device (504) can be used to connect to the filler rod (502) for adding a new tube (510) to the seal block assembly.
摘要:
A fiber management system (20) is disclosed. The fiber management system (20) includes a tray mounting plate (22A) having a front side (44) and a back side (46). The fiber management system (20) also includes a first fiber management tray (26A) connected to the front side (44) of the tray mounting plate (22A). The tray mounting plate (22A) defines a first through-hole (60A) that extends through the tray mounting plate (22A). The fiber management system (20) further includes a first fiber guide tube (62) that extends through the first through-hole (60A) from the back side (46) of the tray mounting plate (22A) to the front side (44) of the tray mounting plate (22A). The first fiber guide tube (62) further extends from the first through-hole (60A) into the first fiber management tray (26A) through a first fiber entrance/exit location (57) of the first fiber management tray (26A).
