Description: TECHNICAL FIELD
[0001] The present disclosure relates generally to cable enclosure, and, more particularly, to a fiber optic closure.
BACKGROUND
[0002] While using the optical fibre cables to enable communication, there remains a requirement to manage bundles of the optical fibre cables. In order to reduce the light loss for the optical fibre cables, the optical fibre cables are required to splice. The splicing of the optical fibre cables involves joining ends of the fibre cable without affecting signal transmission through the spliced fibre cable. The spliced cables need to be handled with care in order to eliminate any possibility of breaking off the spliced fibre cable, which eventually leads to signal loss/attenuation.
[0003] There are various splicing enclosures known in the art that are designed to encase the spliced or joints of the optical fibre cable and simultaneously allow management of the optical cables within the enclosure. One of such splicing enclosure as described in US patent number 5590234. The reference discloses about a number of splicing trays that are stacked such that the splicing trays receive the spliced optical fibre cable. Each splicing tray support unit of the enclosure defines arcuate formations and spools that act as guiding elements for the optical fibre cable passing through the splice enclosure.
[0004] Other US patent references 6275639 and 6304707 incorporated herein disclose splicing enclosure that exhibits different shape and geometrical construction. The references disclose about optical fibre splice holders for holding spliced optical fibre cables. The references also disclose about stacking of the fibre storage trays such that each storage tray stores optical fibre cable.
[0005] The problem associated with the splice enclosures is that the splice enclosure ropes in fixed arcuate formations and guides for routing the optical fibre cable within the splice enclosure. This limits the configurational flexibility of the optical fibre cable within the splice enclosure. Since the splice enclosure is designed to harness a number of optical fibre cable that requires to adjust or modify the configuration of the optical fibre cable within the splice enclosure. Further, avoiding energy losses due to optimised routing of the fibre cable necessitates modification in the configurational arrangement of the optical fibre cable.
[0006] Thus, there is a need for a technical solution that overcomes the aforementioned problems of conventional optical fibre splicing enclosures.

In operation, the optical cable (not shown) having the optical fiber 402 may be inserted into one of the first through fifth ports 112a-112e for e.g., the first port 112b (as shown in FIG. 1A). Further, the optical fiber 402 may be routed towards the first routing structure 114a through the fourth left guiding structure 218d. Further, the optical fiber 402 may be routed towards the second routing structure 114b and thus towards the third right guiding structure 224c. The optical fiber 402 is further routed towards the second left guiding structure 218b and thus towards the first routing structure 114a forming the closed loop. Through the first routing structure 114a, the optical fiber 402 may be routed towards the second routing structure 114b and thus towards the first right guiding structure 224a such that the optical fiber 402 exits the fiber optic closure 100 through one of the one of the first through fifth ports 112a-112e (for e.g., the fourth port 112b). In the illustrated second routing configuration, the first and second wings 108a and 108b are in the first closed position. Specifically, the first and second wings 108a and 108b may be rotated in the anti-clockwise and the clockwise direction, respectively, to realize the first closed position, such that the first and second engagement walls 304 and 312 (as shown in FIG. 3A and FIG. 3B) of the first and second wings 108a and 108b, respectively, are engaged with the optical fiber 402 to route according to the second routing configuration thus ensuring safe containment of the optical fiber 402.
[0043] FIG. 4C illustrates a third routing configuration 406 of the fiber optic closure 100 having the first and second wings 108a and 108b in a second closed position. In operation, the optical cable (not shown) having the optical fiber 402 may be inserted into one of the first through fifth ports 112a-112e (for e.g., the first port 112b). Further, the optical fiber 402 may be routed towards the first routing structure 114a through the fourth left guiding structure 218d. Further, the optical fiber 402 may be routed towards the second routing structure 114b and back towards the first routing structure 114a thus forming the closed loop. Through the first routing structure 114a, the optical fiber 402 may be routed towards the second routing structure 114b and thus towards the first right guiding structure 224a such that the optical fiber 402 exits the fiber optic closure 100 through one of the one of the first through fifth ports 112a-112e (for e.g., the fourth port 112b). In the illustrated third routing configuration, the first and second wings 108a and 108b are in the second closed position. Specifically, the first and second wings 108a and 108b may be rotated in the anti-clockwise and the clockwise direction, respectively, to realize the second closed position, such that the first and second engagement walls 304 and 312 (as shown in FIG. 3A and FIG. 3B) of the first and second wings 108a and 108b, respectively, are engaged with the optical fiber 402 to route according to the third routing configuration thus ensuring safe containment of the optical fiber 402.
[0044] FIG. 5 illustrates a cover unit 500 of the fiber optic closure 100 of FIG. 1A. The cover unit 500 may have a first portion 502 and a second portion 504 such that the first portion 502 and the second portion 504 may be attached to each other to form the cover unit 500. In some aspects of the present disclosure, the first portion 502 and the second portion 504 may be fabricated as a single piece by way of a molding process. Examples of the molding process may include, but is not limited to, a compression molding, a melt molding, a transfer molding, an injection molding, and the like. Aspects of the present disclosure are intended to include and/or otherwise cover any type of the molding process to fabricate the first portion 502 and the second portion 504, including known, related, and later developed molding processes. In some aspects of the present disclosure, the first portion 502 and the second portion 504 may be fabricated using a molding material such as, but not limited to, Polycarbonate (PC), Acrylonitrile butadiene styrene (ABS), Polypropylene (PP), Nylon Plastic (PA), a Glass-filled polymer material, and the like. In some other aspects of the present disclosure, the base 102 may be fabricated using a metal such as stainless steel to provide improved durability in harsh installation conditions. Aspects of the present disclosure are intended to include and/or otherwise cover any type of the molding material for the first portion 502 and the second portion 504.
[0045] As illustrated, the first portion 502 may be a hollow structure that may be adapted to receive the splicing tray support unit 104. The second portion 504 may have an opening 506 that may be adapted to facilitate in insertion of the splicing tray support unit 104 into the hollow structure of the first portion 502. Further, the second portion 504 may have a mating sleeve 508 disposed along a periphery of the opening such that the mating sleeve 508 engages with the base 102 of the fiber optic closure 100 to enclose the splicing tray support unit 104 inside the cover unit 500.
[0046] Thus, the first and second wings 108a and 108b that are pivotally mounted on the splicing tray support unit 104 and adapted to rotate in the anti-clockwise direction and clockwise direction, respectively, may facilitate to provide access to the stored optical fiber 402, that results in various storage directions and configurations based on different requirements. Further, the rotatable first and second wings 108a and 108b facilitates in easy installation of the optical fibers inside the fiber optic closure 100. Furthermore, the fiber guiding unit 106 facilitates in storage of different types of optical fiber cables in one fiber optic closure (i.e., the fiber optic closure 100).
[0047] While various aspects of the present disclosure have been illustrated and described, it will be clear that the present disclosure is not limited to these aspects only. Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the present disclosure, as described in the claims. Further, unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements.
