DETAILED DESCRIPTION
Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
The present disclosure relates to a cable termination arrangement 10 that can be used in both a sliding drawer application and a hinged panel application. FIGS. 1-9 illustrate the cable termination arrangement 10 being utilized as a sliding drawer; FIGS. 10-12 illustrate the cable termination arrangement 10 being utilized as a hinged panel. The present arrangement allows a technician the selectively choose or change the cabling configuration of a telecommunications system without having to invest costs into additional or different structure that houses the cables and cable terminations.
Referring to FIG. 1, the arrangement 10 generally includes a chassis 12 and a drawer 14 that slides relative to the chassis 12. A first hinged access panel 16 is mounted to the drawer 14, and a second hinged access panel 18 is mounted to the chassis 12. The drawer 14 has an interior 20 (FIG. 2). In the illustrated embodiment, the interior 20 is generally defined by the perimeter of the drawer, as the drawer has open sides and an open rear. In the alternative, the drawer can include side walls and/or a rear wall that define the drawer interior. The chassis 12 and the first and second hinged access panels 16, 18 enclose and protect the contents within the interior 20 of the drawer 14.
When used as a sliding drawer, the arrangement 10 is horizontally mounted, for example, to a rack 70 (schematically illustrated in FIG. 1) or other framework. The chassis 12 includes slide structure 22 (e.g., channels; see FIGS. 2 and 7) that receives edges 24 of the drawer 14. The drawer 14 slides within the slide structure 22 between a closed position (FIG. 1) and an open position (FIG. 2) to provide access to the internal cables and terminations.
To access the internal cables and terminations, the drawer 14 is first slid open and the first hinged access panel 16 is then pivoted from a closed position (FIG. 2) to an open position (FIG. 3). The second hinged access panel 18 functions as a top chassis wall. In the illustrated embodiment, cable terminations 26 (FIG. 3), such as fiber optic adapters, are located within the interior 20 of the drawer under the first hinged access panel 16. Other cable management components 68, such as cable radius limiters and cable guides, are located within the interior 20 of the drawer 14 rearward of the cable terminations 26, and are accessible when the drawer 14 is slid open. Examples of other terminations, cable management components, and/or distribution structures that can be provided within the drawer interior and/or chassis include attenuators, couplers, switches, wave divisions multiplexers, splitters, combiners, or splices.
Referring now to FIGS. 4 and 5, one cable routing arrangement of the horizontally-oriented cable termination arrangement 10 is illustrated. In FIG. 4, the first and second access panels 16, 18 are not illustrated for purpose of clarity. In this cable routing arrangement, a main distribution cable 28 enters the chassis 12 through a cable entry opening 30 (see also FIG. 9) located in a wall 32 of the chassis 12. In this particular orientation, the wall 32 is generally a rear wall of the chassis 12. The main distribution cable 28 is routed through a conduit tube 34 and secured to the wall 32 by a Velcro strip 36. The Velcro strip 36 is threaded through tie off structure 38 (FIG. 9) that is integrally formed in the wall 32.
From the opening 30, the main distribution cable 28 is routed around the cable management components 68. Additional tie off structure 60 (FIG. 8) is integrally formed in a wall 62 of the drawer 14. In this particular orientation, the wall 62 is generally a bottom wall of the drawer 14. Another Velcro strip (not shown) is threaded through the tie off structure 60 to secure the main distribution cable 28 relative to the drawer. A predetermined length of cable slack between the two securing points (e.g., 38, 60) is provided to accommodate the sliding movement of the drawer 14 from the closed position (FIG. 4) to the open position (FIG. 5).
Referring still to FIGS. 4 and 5, individual cable fibers 40 of the main distribution cable 28 are routed to the cable terminations 26 located forward of the cable management components 68. In the illustrated embodiment, the cable terminations 26 include adapters 42 having a front connection location 44 and a rear connection location 46. The individual cable fibers 40 from the main cable 28 terminate at the rear connection locations 46. Associated cables 48, such as patch cords, terminate at the front connection locations 44 of the adapters 42. The associated cables 48 exit the drawer 14 through a cable exit opening 50 located at a front 52 of the drawer 14. The cable exit opening 50 of the drawer 14 is defined by a notch 56 (FIG. 2) formed in a front wall 54 of the drawer, a notch 74 formed in the bottom wall 62 of the drawer, and a corresponding notch 58 formed in the first access panel 16 of the arrangement 10.
Referring now to FIGS. 10 and 11, the cable termination arrangement 10 is oriented for use as a hinged panel. The arrangement 10 can be, for example, mounted within the interior of a cabinet 72 (partially illustrated) and used for cable terminations and/or cable management within the cabinet. When used as a hinged panel, the arrangement 10 is vertically mounted, for example, to an interior wall or other support structure within the cabinet interior. The cable termination arrangement can also be vertically mounted to an exterior wall or other framework structure.
To access the interior 20 of the arrangement 10, the first and second hinged access panels 16, 18 (e.g., doors) are pivoted from the closed position (FIG. 10) to the open position (FIG. 11). In the illustrated embodiment, the cable terminations 26 are located within the interior 20 of the drawer 14 behind the first hinged access panel 16, while the cable management components 68 are located within the interior 20 behind the second hinged access panel 18.
Referring now to FIG. 12, one cable routing arrangement of the vertically-oriented cable termination arrangement 10 is illustrated. In this cable routing arrangement, the main distribution cable 28 enters the chassis 12 through the cable entry opening 30 (see also FIG. 11) located in the wall 32 of the chassis 12. In this particular orientation, the wall 32 is generally a side wall of the chassis 12. The main distribution cable 28 is routed through the conduit tube 34 and secured to the wall 32 by the Velcro strip (see e.g., FIG. 4). The Velcro strip is threaded through the tie off structure 38 (FIG. 11) that is integrally formed in the wall 32.
From the opening 30, the main distribution cable 28 is routed around the cable management components 68. Additional tie off structure 60 (see also FIG. 8) is integrally formed in the wall 62. Another Velcro strip (not shown) is threaded through the tie off structure 60 to secure the main distribution cable 28 within the interior (i.e., 20).
Referring still to FIG. 12, the individual cable fibers 40 of the main distribution cable 28 are routed to the cable terminations 26. As previously described, the cable terminations 26 include the adapters 42 having the two connection locations, for example, the now leftward facing connection locations 44 and the now rightward facing connection locations 46. The individual cable fibers 40 from the main cable 28 terminate at the rightward facing connection locations 46. Associated cables 48, such as patch cords, terminate at the leftward facing connection locations 44 of the adapters 42. The associated cables 48 exit the drawer 14 through the cable exit opening 50 of the arrangement 10.
The above specification provides a complete description of the present invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, certain aspects of the invention reside in the claims hereinafter appended.
