Telecommunications systems typically receive subscriber or distribution cables, splice these fiber optic cables to a pigtail cable, and connect the pigtail cable to fiber optic equipment. To organize the fiber optic cables and equipment, fiber distribution cabinets are used. Fiber distribution cabinets permit connections to various fiber optic equipment using patch cords, and provide splice areas for splicing incoming cables containing one or more optical fibers.
There is a continuous need to maintain a high-density fiber distribution cabinets. There are further needs to improve accessibility to the patch cords and splice areas, enhance fiber optic cable management, and avoid excessive bending and stresses on the various fiber optic cables.
This disclosure relates to the organization of optical fibers within a telecommunications enclosure. More specifically, the telecommunication enclosure includes a frame that allows access to one or more termination panels on a front plane and access to one or more splice areas on a lateral side plane to allow multiple workers to work on the enclosure simultaneously.
In one aspect, a telecommunications enclosure comprises a frame; first and second termination panels mounted to the frame, the first and second termination panels being accessible from a front plane, the first and second termination panels each including a plurality of cable termination locations; and at least one splice area positioned inside the frame, the at least one splice area being accessible from a right side plane or a left side plane, and the at least one splice area configured to receive fiber optic cables for splicing to additional cables inside the frame.
In another aspect, a telecommunications enclosure comprises a frame; first and second termination panels mounted to the frame, the first and second termination panels being accessible from a front plane of the frame, the first and second termination panels each including a plurality of cable termination locations; and at least one splice area positioned inside an interior of the frame, the at least one splice area being accessible from a lateral side plane, the at least one splice area configured to receive fiber optic cables for splicing to additional cables inside the frame; wherein the at least one splice area is slidable from the interior of the frame to an exterior of the frame such that the at least one splice area is configured to extend beyond the lateral side plane to improve accessibility of the at least one splice area, and wherein the at least one splice area includes a stacked arrangement of splice trays.
A variety of additional inventive aspects will be set forth in the description that follows. The inventive aspects can relate to individual features and to combinations of features. It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.
The accompanying drawings, which are incorporated herein and constitute a part of the description, illustrate several exemplary aspects of the present disclosure.
The telecommunications system 10 includes a frame 12 that supports one or more termination panels (such as first and second termination panels 16a, 16b) and one or more splice areas (such as first and second splice areas 18a, 18b). A plurality of cable management devices 20 are mounted to the frame 12 to manage a plurality of patch cords 22 that run between a first termination panel 16a and a second termination panel 16b. The cable management devices 20 limit cable bend radius and manage cable slack. In some examples, the cable management devices 20 are cable radius limiters, spools, and the like. The patch cords 22 can be used to cross-connect between various termination locations on the termination panels.
As shown in
The first and second termination panels 16a, 16b are accessible from the front plane 30 of the frame 12 while at least one splice area 18 is accessible from the right side plane 34 or left side plane 36 of the frame 12. Advantageously, a first worker can access the first and second termination panels 16a, 16b on the front plane 30 of the frame 12 while a second worker accesses a splice area 18 from the right side plane 34 or the left side planes 36 of the frame 12 such that more than one worker may work on the telecommunications system 10 at the same time.
In the example illustrated in
The first and second front doors 50, 52 are pivotally attached to the frame 12 about hinges 53, 55, respectively. The first and second front doors 50, 52 can each swing from a closed position to an opened position to provide access to the first and second termination panels 16a, 16b and can each swing from the opened position to the closed position to block access to the first and second termination panels 16a, 16b, and thereby protect these components.
The first and second front doors 50, 52 swing about their respective hinges 53, 55 in opposite directions to open and close access to the first and second termination panels 16a, 16b, respectively. The first front door 50 swings about hinge 53 from the closed position to the opened position (e.g., in the counterclockwise direction) to provide access to the first termination panel 16a while the second front door 52 swings about hinge 55 from the closed position to the opened position (e.g., in the clockwise direction) to provide access to the second termination panel 16b. Also, the first front door 50 swings about hinge 53 from the opened position to the closed position (e.g., in the clockwise direction) to block access to the first termination panel 16a while the second front door 52 swings about hinge 55 from the opened position to the closed position (i.e., the counterclockwise direction) to block access to the second termination panel 16b.
As further shown in the example illustrated in
Similarly, the second termination panel 16b is pivotally attached to the frame 12 about hinge 19 such that the second termination panel 16b can swing about the hinge 19 from a storage position to an access position to provide access to a plurality of cable termination locations 23 on the second termination panel 16b. Thus, the cable termination locations 23 are positioned on an interior surface of the second termination panel 16b that can be accessed by a worker by swinging the second termination panel 16b about the hinge 19.
When swinging from the storage position to the access position, the first and second termination panels 16a, 16b swing about their respective hinges 17, 19 in opposite directions. For example, the first termination panel 16a swings about hinge 17 in a clockwise direction from the storage position to the access position while the second termination panel 16b swings about hinge 19 in a counterclockwise direction from the storage position to the access position.
Also, the first and second termination panels 16a, 16b swing about their respective hinges 17, 19 in directions opposite their respective first and second front doors 50, 52. For example, the first termination panel 16a swings about hinge 17 from the storage position to the access position in a clockwise direction while the first front door 50 swings about hinge 53 from the closed position to the opened position in a counterclockwise direction. The second termination panel 16b swings about hinge 19 from the storage position to the access position in a counterclockwise direction while the second front door 52 swings about hinge 55 from the closed position to the opened position in a clockwise direction. The relative swinging between the first and second termination panels 16a, 16b and the first and second front doors 50, 52 enhances access to the cable termination locations 21, 23 when the first and second front doors 50, 52 are in the opened position and the first and second termination panels 16a, 16b are in the access positions.
Furthermore, when the first termination panel 16a is in the access position, a worker who is working on the cable termination locations 21 is blocked from accessing the cable termination locations 23 on the second termination panel 16b. Similarly, when the second termination panel 16b is in the access position, a worker who is working on the cable termination locations 23 is blocked from accessing the cable termination locations 21 on the first termination panel 16a. Advantageously, the relative swinging of the first and second termination panels 16a, 16b demarcates the cable termination locations 21, 23 such that a worker does not confuse one cable termination location for the other.
As further shown in
In the illustrated example, the first and second splice areas 18a, 18b can each include a plurality of splice trays 14. Each splice tray 14 includes structure for holding the ends of a plurality of fiber optic cables, and for holding individual splices between the ends of the cables. A variety of splice trays 14 may be used. The splice trays 14 can be pivotally mounted to groove plates 15 that are designed with slots for routing fibers to and from the splice trays 14.

When the first side door 60 is swung from the opened position to the closed position, the splice trays 14 attached to the first side door 60 are held inside a splice tray storage area 24a. When the second side door 62 is swung from the opened position to the closed position, the splice trays 14 attached to the second side door 62 are held inside a splice tray storage area 24b. Advantageously, the splice tray storage areas 24a, 24b are adjacent to the cable termination locations 21, 23 on the first and second termination panels 16a, 16b. This provides a compact arrangement that reduces the footprint of the telecommunications system 10.
Advantageously, when the first side door 60 is swung into the opened position (i.e., swung in the counterclockwise direction about hinge 63), a worker can slide the first stacked arrangement 70 along the rails 74, 76 in the first direction D1 (e.g., to the right) such that the first stacked arrangement 70 with the splice trays 14 pivotally attached thereto can extend beyond the right side plane 34 to improve the accessibility of the splice trays 14 in the first splice area 18a. After the worker completes work on the splice trays 14 in the first splice area 18a, the worker can slide the first stacked arrangement 70 along the rails 74, 76 in the second direction D2 (e.g., to the left) to move the first stacked arrangement 70 with the splice trays 14 pivotally attached thereto back inside the splice tray storage area 24a. Thereafter, the worker can swing the first side door 60 into the closed position (i.e., swing the first side door 60 in the clockwise direction about hinge 63) to block access to the splice trays 14 in the first splice area 18a.
Similarly, when the second side door 62 is swung into the opened position (i.e., swung in the clockwise direction about hinges 65), a worker can slide the second stacked arrangement 72 along the rails 78, 80 in the second direction D2 (e.g., to the left) such that the second stacked arrangement 72 with the splice trays 14 pivotally attached thereto can extend beyond the left side plane 36 to improve the accessibility of the splice trays 14 in the second splice area 18b. After the worker completes work on the splice trays 14 in the second splice area 18b, the worker can slide the second stacked arrangement 72 along the rails 78, 80 in the first direction D1 (e.g., to the right) to move the second stacked arrangement 72 with the splice trays 14 pivotally attached thereto back inside the splice tray storage area 24b. Thereafter, the worker can swing the second side door 62 into the closed position (i.e., swing the second side door 62 in the counterclockwise direction about hinge 65) to block access to the splice trays 14 in the second splice area 18b.
When the first stacked arrangement 70 is sled back inside the splice tray storage area 24a, the splice trays 14 are adjacent to the cable termination locations 21 on the first termination panel 16a. Similarly, when the second stacked arrangement 72 is sled back inside the splice tray storage area 24b, the splice trays 14 are adjacent to the cable termination locations 23 on the second termination panel 16b. Advantageously, this provides a compact arrangement inside the telecommunications system 10 that reduces the footprint of the telecommunications system 10.
After the worker completes work on the splice trays 14 in the first splice area 18a, the worker can slide the splice trays 14 along the rails 92 in the second direction D2 (e.g., to the left) and transition the splice trays 14 back onto the rails 90 attached to the rear panel 94 to store the splice trays 14 inside the splice tray storage area 24a. Thereafter, the worker can swing the first side door 60 into the closed position to block access to the splice trays 14.
The splice trays 14 and groove plates 15 in the second splice area 18b are mounted to one or more rails 96 attached to the rear panel 94 of the frame 12. The second side door 62 includes one or more rails 98 that align with the rails 96 when the second side door 62 is swung into the opened position such that a worker can slide the splice trays 14 along the rails 96 in the second direction D2 (e.g., to the left) and transition the splice trays 14 onto the rails 98 attached to the second side door 62. Advantageously, this allows the splice trays 14 in the second splice area 18b to be accessible on the second side door 62, and thereby improves their accessibility.
After the worker completes the work on the splice trays 14 in the second splice area 18b, the worker can slide the splice trays 14 along the rails 98 in the first direction D1 (e.g., to the right) and transition the splice trays 14 back onto the rails 96 attached to the rear panel 94 to store the splice trays 14 inside the splice tray storage area 24b. Thereafter, the worker can swing the second side door 62 into the closed position to block access to the splice trays 14.
When the splice trays 14 are sled back inside the splice tray storage area 24a, the splice trays 14 in the first splice area 18a are adjacent to the cable termination locations 21 on the first termination panel 16a. Similarly, when the splice trays 14 are sled back inside the splice tray storage area 24b, the splice trays 14 in the second splice area 18b are adjacent to the cable termination locations 23 on the second termination panel 16b. This provides a compact arrangement inside the telecommunications system 10 that reduces the footprint of the telecommunications system 10.
First and second front doors 120, 122 are pivotally attached to the frame 102 about hinges 124, 126, respectively. The first and second front doors 120, 122 can be swung from a closed position to an opened position to provide access to first and second termination panels 130a, 130b. The first and second front doors 120, 122 can be swung from the opened position to the closed position to block access to the first and second termination panels 130a, 130b. The first and second front doors 120, 122 can also include a lock 151 to prevent unauthorized access to the first and second termination panels 130a, 130b.
Stay open devices 123 (see
A plurality of cable management devices 132 are mounted to the frame 102 between the first and second termination panels 130a, 130b. The cable management devices 132 manage a plurality of fiber optic cables that run inside the telecommunications system 100. For example, the cable management devices 132 can manage a plurality of patch cords that run between the first and second termination panels 130a, 130b. The cable management devices 132 limit cable bend radius and manage cable slack. In some examples, the cable management devices 132 are cable radius limiters, spools, and the like. The patch cords can be used to cross-connect between various termination locations on the first and second termination panels 130a, 130b. The cable management devices 132 can define a cable slack storage area 139 (see
First and second side doors 140, 142 are pivotally attached to the frame 102 about hinges 144, 146, respectively. The first and second side doors 140, 142 can be swung from a closed position to an opened position to provide access to first and second splice areas 150a, 150b, respectively, and can be swung from the opened position to the closed position to block access to the first and second splice areas 150a, 150b, respectively. The first and second side doors 140, 142 can each include a lock 153 to prevent unauthorized access to the first and second splice areas 150a, 150b inside the telecommunications system 100.
Stay open devices 143 are mounted to the first and second side doors 140, 142 and to the frame 102. When actuated, the stay open devices 143 maintain the first and second side doors 140, 142 in the opened position. When released, the stay open devices 143 allow the first and second side doors 140, 142 to swing between the opened and closed positions.
The first and second splice areas 150a, 150b can each slide between a storage position and an access position in directions substantially parallel to the rear plane 106. For example, the first splice area 150a can slide in a first direction D1 (e.g., to the right) such that the first splice area 150a can slide from the storage position to the access position. When in the access position, the first splice area 150a extends beyond the right side plane 108 to improve the accessibility of the first splice area 150a. Similarly, the second splice area 150b can slide in an opposite, second direction D2 (e.g., to the left) such that the second splice area 150b can slide from the storage position to the access position. When in the access position, the second splice area 150b extends beyond the left side plane 110 to improve the accessibility of the second splice area 150b.
When the first side door 140 is swung into the opened position, a worker can slide the first panel 152 along the rails 160, 162 in the first direction D1 such that the first panel 152 with the first splice area 150a attached thereto can extend beyond the right side plane 108 to improve the accessibility of the first splice area 150a. After the worker completes work on the first splice area 150a, the worker can slide the first panel 152 along the rails 160, 162 in the second direction D2 (e.g., to the left) to move the first panel 152 with the first splice area 150a attached thereto back inside the frame 102. Thereafter, the worker can swing the first side door 140 into the closed position to block access to the first splice area 150a inside the frame 102.
Similarly, when the second side door 142 is swung into the opened position, a worker can slide the second panel 154 along the rails 164, 166 in the second direction D2 (e.g., to the left) such that the second panel 154 with the second splice area 150b attached thereto can extend beyond the left side plane 110 to improve the accessibility of the second splice area 150b. After the worker completes work on the second splice area 150b, the worker can slide the second panel 154 along the rails 164, 166 in the first direction D1 (e.g., to the right) to move the second panel 154 with the second splice area 150b attached thereto back inside the frame 102. Thereafter, the worker can swing the second side door 142 into the closed position to block access to the second splice area 150b inside the frame 102 of the telecommunications system 100.

The first and second termination panels 130a, 130b each include a stay open device 133. When actuated, the stay open device 133 can be used to maintain the first and second termination panels 130a, 130b in the access position. When the stay open device 133 is released, the first and second termination panels 130a, 130b can rotate between the access and storage positions. Also, the first and second termination panels 130a, 130b can each include a lock to prevent unauthorized access to an interior side of the first and second termination panels 130a, 130b.
As an illustrative example, the first and second splice areas 150a, 150b can each include four groove plates 118, and each groove plate 118 is configured to hold eight splice trays 116 such that the first and second splice areas 150a, 150b can each include 32 splice trays 116. Alternative examples are possible where each splice area may include more than or fewer than four groove plates 118, and each groove plate 118 can be configured to hold more than or fewer than eight splice trays 116 such that the first and second splice areas 150a, 150b can include more than or fewer than 32 splice trays 116.

The feeder cables 111 that enter the frame 102 via the cable glands 121 are routed vertically to the second splice area 150b by one or more guides 117 attached to a bottom groove plate 118. In the second splice area 150b, the feeder cables 111 are spliced to pigtail cables 113 on the splice trays 116. The pigtail cables 113 are managed by a plurality of cable management devices 119 inside the frame 102 such as various cable rings positioned on the frame 102 and various cable rings and trays on an interior side of the second termination panel 130b.
