Abstract
Description
Attorney Docket No.AFLIG-213-PCTMODULAR PANEL AND HIGH DENSITY FIBER OPTIC ENCLOSUREPRIORITY STATEMENT
[0001] The present disclosure claims the benefit of priority to U.S. provisional patent application no. 63 / 721,003, filed November 15, 2024, the disclosure of which is incorporated by reference herein in its entirety.FIELD
[0002] The present disclosure relates generally to modular panels for use in high density data centers.BACKGROUND
[0003] High density modular panels have become common requirements within hyperscale data centers over the past decade. An exemplary' need for high density modular panels includes a need to house a minimum of 144 LC connections within a I rack-unit (RU) space spread over three rows and utilizing three slidable trays. Each of such trays are required to house multiple widths of cassettes with differing fiber counts. The differing widths of cassette results in multiple widths of cassettes per row, and potentially with different combinations and arrangements of cassettes among the trays.
[0004] Cordage exiting the cassettes may require routing forward and being contained within the RU height of a single tray. The cordage must be managed to route either left or right on the tray. Management elements at the tray may be designed to control the path of such cords. However, such management elements may interfere with installation of the cassettes given the differing widths of the cassettes.
[0005] One solution is to temporarily remove the cord management elements to facilitate installation of the cassettes. However, removing the cord management elements risks losing or damaging the component. Additionally, or alternatively, the process of removing and reinstalling the cord management element adds time to hyperscale data center setup that significantly negatively impacts timely setup, execution, and costs.Attorney Docket No.AFLIG-213-PCT
[0006] As such, there is a need for a modular panel that facilitates receiving cassettes of various widths, promotes desired cordage routing, and removes a need to remove and reinstall cord management elements.
[0007] Accordingly, improved modular panels would be advantageous.Specifically, modular panels which address one or more of the above-stated deficiencies would be advantageous.BRIEF DESCRIPTION

[0019] Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present invention.Atorney Docket No.AFLIG-213-PCTDETAILED DESCRIPTION
[0020] Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
[0021] As used herein, the terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “includes” and “including” are intended to be inclusive in a manner similar to the term “comprising.” Similarly, the term “or” is generally intended to be inclusive (i. e. , “A or B” is intended to mean “A or B or both”). In addition, here and throughout the specification and claims, range limitations may be combined and / or interchanged. Such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherw ise. For example, all ranges disclosed herein are inclusive of the endpoints, and the endpoints are independently combinable with each other. The singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise.
[0022] Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “generally,” “about,” “approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value, or the precision of the methods or machines for constructing or manufacturing the components and / or systems. For example, the approximating language may refer to being within a 10Attorney Docket No.AFLIG-213-PCTpercent margin, i.e., including values within ten percent greater or less than the stated value. In this regard, for example, when used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction, e.g., ‘'generally vertical” includes forming an angle of up to ten degrees in any direction, e.g., clockwise or counterclockwise, with the vertical direction V.
[0023] The word “exemplary ” is used herein to mean “serving as an example, instance, or illustration.” In addition, references to “an embodiment” or “one embodiment” does not necessarily refer to the same embodiment, although it may. Any implementation described herein as “exemplary” or “an embodiment” is not necessarily to be construed as preferred or advantageous over other implementations. Moreover, each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
[0024] As used herein, “substantial” translation or extension of a member, void, or surface(s) forming a void described herein refers to a major axis of extension or a greater dimension of extension compared to a minor axis of extension or lesser dimension of extension. For instance, a member “extending substantially” along a length direction acknowledges the member having three-dimensions (e.g., a thickness) that would extend in mutually orthogonal width and height directions in addition to the length direction. However, in such instance, the dimension of the member along the length direction is greater than dimensions along the width or height direction. In another instance, a void “extending substantially” along a length direction and a height direction acknowledges that an extension of the void along the width direction may exist but is lesser in magnitude than the length direction and height direction.
[0025] As used herein, the term “rack unit” (RU) is understood by those skilled in the art as a unit of measure of approximately 1.75 inches (in) or approximately 44.45Attorney Docket No.AFLIG-213-PCTmillimeters (mm), or up to 0.03125 in or 0.794 mm less when applied to telecommunications equipment attached to a mount structure.
[0026] Dimensions provided herein may include approximations of + / -2% of any discrete quantity, or approximations of +2% of a maximum value over a given range or -2% of the maximum value under the given range, unless otherwise provided herein.
[0027] Referring now to the drawings. Figs. 1-5 depict embodiments of a high density enclosure for fiber optic cables. A mutually orthogonal width direction W, transverse direction T, and height direction H are provided for reference.
[0028] An improved high density enclosure 100 is provided addressing the challenges identified above. Embodiments of the enclosure 100 include a modular panel 200 having a plurality of walls 210 forming an enclosed volume into which a cassette tray 300 is permitted to articulate. The cassette tray 300 is configured to receive a plurality of cassettes 400 arrangeable along a width direction W of the cassette tray 300. A cable management tray 500 is attachable to the cassette tray 300 and extended along the transverse direction T forward of the cassette tray 300.
[0029] Embodiments of the enclosure 100 may further include a door 570 configured to rotate, such as to enclosure the volume at which the panels 200 are positioned within the enclosure 100.
[0030] The cassette tray 300 includes a first member 310 and the cable management tray 500 includes a second member 510. The first and second members 310, 510 each extend substantially along the transverse direction T orthogonal to the width direction W. The first and second members 310, 510 together have an attachment interface 550 coupling the cable management tray 500 to the cassette tray 300.
[0031] The attachment interface 550 includes a first protrusion 512 extending from the second member 510 and a corresponding opening 312 extending into the first member 310. The attachment interface 550 includes a second protrusion 514 extending from the second member 510. The first member 310 includes a slot 314 extending substantially along the transverse direction T. The slot 314 includes a first portion 324 and a second portion 334. The second portion 334 extends along the height direction H greater than the first portion 324 such that the second protrusionAttorney Docket No.AFLIG-213-PCT514 is articulatable along the height direction H within the second portion 334 of the slot 314.
[0032] The second protrusion 514 is articulatable along the transverse direction T between the first portion 324 and the second portions 334 of the slot 314. The first portion 324 positions the cable management tray 500 in a first angular position relative to the cassette tray 300, such as depicted in Fig. 2 at position 550A or in Fig.3A. The second portion 334 permits the second protrusion 514 to articulate along the height direction H to position the cable management tray 500 in a second angular position relative to the cassette tray 300, such as depicted in Fig. 2 at position 550B or in Fig. 5. The second protrusion 514 may be positioned in the second portion 334 in an intermediate position, such as depicted in Fig. 3B, between articulating the second protrusion 514 toward the first portion 324 or vertically upward within the second portion 334.
[0033] In exemplary embodiments, the modular panel 100 forms the first and second members 310, 510 as an integrated latch permitting articulation of the cable management tray 500 in front of the cassettes 400. In some embodiments, cordage management elements 560, such as tabs, loops, or standoffs, extend from the cable management tray 500. The cordage management elements 560 may be integrally formed to the cable management tray 500. For instance, in various embodiments, the cable management tray 500 includes the cordage management elements 560 as a unitary, inseparable, monolithic component. Accordingly, the integrated cordage management elements 560 are permitted to articulate with the cable management tray 500 as the cable management tray 500 is rotated or tilted down with articulation of the second protrusion 514 along the height direction H.
[0034] By articulating the attachment interface 500 forming a latching mechanism, the cassettes 400 are permitted to pass along the transverse direction T over cordage management elements 560 and install directly onto the cassette tray 300 without the need to remove any parts or components from the cable management tray 500.
[0035] Once the cassettes 400 have been installed, the cable management tray 500 can be articulated back into the first angular position 550A (e.g., a resting position) and the cordage management elements 560 can be utilized to route the cordage. InAttorney Docket No.AFLIG-213-PCTexemplary7embodiments, the angle of the tilt (e.g., angle of change between the first angular position 550A and second angular position 550B) is limited to the minimum required to allow the cassettes 400 to be passed over along the transverse direction T and allowing installation onto the cassette tray 300.
[0036] In various embodiments, the second protrusion 514 is configured such that the second protrusion 514 is bound by surrounding faces 316 of the first portion 324 such that articulation of the second protrusion 514 along the height direction H is inhibited when the second protrusion 514 is positioned at the first portion 324, such as forming the first angular position or resting position.
[0037] In still various embodiments, the second portion 334 is configured such that surrounding faces 318 of the second portion 334 permit articulation of the second protrusion 514 along the height direction H when the second protrusion 514 is positioned at the second portion 334, such as forming the second angular position or tilted position.
[0038] In some embodiments, surrounding faces 318 of the second portion 334 include an upper face forming a detent along the height direction H.
[0039] The second member 510 may include a body 515 positioned adjacent to a first face 315 of the first member 310. The first and second protrusions 512, 514 extend from the body 515, such as substantially along the width direction W to insert into the opening 312 and slot 314, respectively.
[0040] The second protrusion 514 may extend through the slot 314 such that at least a portion of the second protrusion 514 is positioned adjacent to a second face 317 of the first member 310 opposite along the width direction W from the first face 315. For instance, the second protrusion 514 may include ahead retaining a neck of the second protrusion 514 within the slot 314.
[0041] The body 515 may include a detent face 517 positioned between the first face 315 and the second face 317. The detent face 517 is configured to abut the surrounding faces 318 at the upper face when the cable management tray 500 is in the second angular position 550B. As such, the detent face 517 may help limit a tilt or angular change of the cable management tray 550 between the first and second angular positions 550A, 550B.Attorney Docket No.AFLIG-213-PCT
[0042] The upper face of the surrounding faces 318 may include an oblique angular portion 319 configured to receive the second protrusion 514. The oblique angular portion 319 corresponds to the desired second angular position 550B of the cable management tray 500 relative to the cassette tray 300. For instance, the oblique angular portion 319 may be oblique relative to substantially transversely -oriented surrounding faces 318 at the second portion 334. The oblique angular portion 319 may form a key or recess at which the second protrusion 514 is received when articulated along the height direction H.
[0043] The second portion 334 of the slot 314 and second protrusion 514 may include corresponding rounded ends 336, 536. The rounded end 536 of the second protrusion 514 may be configured to be received at the rounded end 336 of the second portion 334 when the second protrusion 514 is positioned in the second portion 334 of the slot 314. The rounded ends 336, 536 may facilitate rotation and tilting of the cable management tray 500 between the first second angular positions 550A, 550B. For instance, when the second protrusion 514 articulated along the height direction H (e.g., into the oblique angular portion 319), the rounded ends 336, 536 may facilitate pivoting the cable management tray 500 between first and second angular positions 550A, 550B.
[0044] In various embodiments, the first and second members 310, 510 extending substantially along the transverse direction T are positioned, at least in part, adjacent to one another along the width direction W. As such, the first and second protrusions 512, 514 may extend along the width direction W into the opening 312 and slot 314, respectively.
[0045] In still various embodiments, the first protrusion 512 is positioned along the transverse direction T more distal than the second protrusion 514 from the cassette tray 300 and cassettes 400. Stated differently, the first protrusion 512 may be positioned at the second member 510 more forward from the panel 200 than the second protrusion 514. In still yet various embodiments, rounded ends 336, 536 may be positioned along the transverse direction T between the first portion 324 and the opening 312.
[0046] The opening 312 and first protrusion 512 may form a lock or latch that, when removed from one another, permits articulation of the cable management trayAttorney Docket No.AFLIG-213-PCT500 along the transverse direction T. The second protrusion 514 translates correspondingly from the first portion 324 of the slot 314 (e.g., when the first protrusion 512 is inserted into the opening 312) to the second portion 334, such as permitting articulation of the second protrusion 514 along the height direction H to rotate or tilt the cable management tray 500 from the first angular position 550A to the second angular position 550B.
[0047] Embodiments of the first and second members 310, 510 providing lock or latch structures such as described may remove a need for magnetically fastened structures. For instance, opening 312 and / or slot 314 provided herein, and corresponding protrusions 512, 514, may remove a need for magnets, or magnets bonded with epoxy, such that epoxy failure may be avoided.
[0048] In some embodiments, the second member 510 includes a user interface tab 530 positioned distal along the transverse direction T from the cassette tray 300. The user interface tab 530 protrudes along the width direction W and provides a portion of the second member 510 at which a user may grab, bend, and flex the second member 510 to release the first protrusion 512 from the opening 312 and articulate the second member 510 relative to the first member 310 such as described herein.
[0049] The second member 510 may include a more flexible, compliant material than the first member 310, such as may promote bending and flexing to position, insert, and remove the first protrusion 512 from a locked position in the opening 312.
[0050] In various embodiments, the panel 200 and the cassette tray 300 together include a tray attachment interface 250 coupling the cassette tray 300 to the panel in transversely articulatable arrangement. The tray attachment interface 250 may include a rail and channel structure along which cassette tray 300 is permitted to slide along the transverse direction T, such as between inserted and removed positions depicted in Figs. 1-2.
[0051] In still various embodiments, the cassette tray 300 includes a pair of the first members 310 extending substantially along the transverse direction T from respective tray attachment interfaces 250. The cassette tray 300 includes a rail 360 extending substantially along the transverse direction T to a cross member 362 extending along the width direction W betw een the pair of the first members 310.Attorney Docket No.AFLIG-213-PCT
[0052] The rail 360 may provide a structure along which cassettes 400 form mounting channels. The mounting channels may further delineate or partition portions of the cassette 400 from one another, such as provide bounds between groups of connectors, or bounds between different types of connectors (e.g., simplex versus duplex multifiber connectors, different types of single or multifiber connectors, etc.). The rail 360 may provide a securing or positioning feature at the cassette tray 300 such as to situate and organize the cassettes 400.
[0053] In some embodiments, however, positioning of the rail 360 may require the cable management tray 500 to be repositioned to provide ingress and egress access of the cassettes 400 from the cassette tray 300, or in some embodiments, from the rail 360 at the cassette tray 300. As such, embodiments, of the attachment interface 550 providing a tilting mechanism such as described herein may facilitate utilizing cassettes 400 of various widths and positioned utilizing the transversely-extended rail 360 at the cassette tray 300 such as depicted and described herein, without requiring removal or separation of cords or cordage management elements 560 from the cable management tray 500.
[0054] Exemplary embodiments of the high density fiber optic enclosure depicted and described herein may solve the above-identified challenges by providing improved modular panels, such as including tilting mechanisms provided herein. Such modular panels may be utilized in high density data center enclosures.
[0055] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
