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： 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.

摘要： Example management closures (110) enable incoming optical and/or electrical signals to be connected to one or more subscribers (109) via an electrical distribution cable (102). Termination connections within the management closure (110) are connected to active electronic equipment (131) for modifying and/or enhancing the incoming signals. However, the connections between the central office (101), the active electronic equipment (131), and a subscriber (109) need not be made until the subscriber requests a service upgrade. Accordingly, the closure (110) allows for simple and low cost installation of the closure (110) before upgraded service is needed.
