Abstract:
A seal block assembly (10) includes a housing (12) defining one or more slots (14). Seal block assembly seals a port of a telecommunications box or enclosure. Each seal block element (32) includes a seal block body (34) having first and second body portions (36, 38), and first and second seal portions (40, 42) for sealing around a cable. A sealing system is provided between each seal block element and an adjacent seal block element. A sealing arrangement is also provided between the seal block elements and the slot.
Abstract:
A two layer splitter tray (18) has a cover (32) which mounts to a base (34). The base (34) and the cover (32) define openings for one or more splitters (88). The base (34) and cover (32) include cable management devices (42, 64) for managing the cable and fiber inputs and outputs, and the splices. Further splice trays (16) can be used with the splitter tray (18) for splicing to the splitter outputs. Other trays (100, 200) include a partial cover (140, 240) and openings for optical components and for adhesive attachment of parts.
Abstract:
A telecommunications system (10/100) is disclosed herein. The telecommunications system (10/100) includes a chassis (12/112) defining a top end (14/114), a bottom end (16/116), and a generally pyramidal shape, wherein a transverse cross-sectional footprint (28) of the chassis (12/112) changes in outer dimension as the transverse cross-sectional footprint (28) extends from the top end (14/114) to the bottom end (16/116), the telecommunications chassis (12/112) further defining at least one sidewall (30/130, 32/132, 34/134, 36/136), the at least one sidewall (30/130, 32/132, 34/134, 36/136) extending at an angle to both the top end (14/114) and the bottom end (16/116), the at least one sidewall (30/130, 32/132, 34/134, 36/136) defining ports (38) defining connection locations for receiving telecommunications equipment.
Abstract:
An enclosure (20, 220) includes a housing (22, 222) and a sealing unit (48, 42a, 232) that mounts within a sealing unit opening (28, 230) of the housing. The sealing unit (48, 42a, 232) provides a peripheral seal between the housing (22, 222) and the sealing unit (48, 42a, 232) and provides seals around cable ports (50). The sealing unit (48, 42a, 232) can be mounted to and removed from the housing (222) through the sealing unit opening (28, 230). The base (26) lacks a permanent retention structure (55, 155a) at the outer end of the base (26) for retaining the sealing unit (48, 42a, 232) in the base (26). A cover (24) is removable from the base (26) without requiring the sealant arrangement (52, 236) to be de-pressurized. A fastening arrangement (55, 155a) releasably retains the sealing unit (48, 42a, 232) in the sealing unit opening (28, 230).
Abstract:
A visual inspection system (100, 200) for optical fibers (150) includes at least a pattern source (120, 220A, 220B, 220C, 520); at least a first illumination source (130, 230A, 230B, 230C, 510, 522) to direct light towards an optical fiber (150); and at least a first camera (140, 240A, 240B, 240C, 540) positioned at an opposite side of the fiber (150) from the pattern source (120, 220A, 220B, 220C, 520). At least one image (170, 180, 190) of the optical fiber (150) is taken and a pattern visible through the optical fiber (150) in the image (170, 180, 190) may be analyzed to detect distortions in the pattern.
Abstract:
An apparatus (10) for mounting blown fiber tubes (20) includes a main housing (40) mountable to an end (32) of a flex tube (30), an outer ring (50) positioned at an end (42) of the main housing (40), and an inner ring (60) positioned adjacent to and within the outer ring (50) wherein the blown fiber tubes (20) are positioned about an outer periphery (62) of the inner ring (60). A trigger (70) pushes the inner ring (60) to compress the blown fiber tubes (20) between the inner ring (60) and the outer ring (50). The outer ring (500 and the inner ring (60) each include a plurality of spaced pockets (52, 68) each sized for receipt of a blown fiber tube (20). The trigger (70) includes a threaded member (80) which pushes the inner ring (60) outwardly. In one embodiment, portions (64) of the inner ring (60) separate during activation and press against the blown fiber tubes (20) to compress the blown fiber tubes (20) against the outer ring (50). A spring (496) may be added to push on the inner ring (60). Anti-rotation and lock features are provided for the compression, sealing and fixation mechanisms.
