Description:TECHNICAL FIELD
The present disclosure relates generally to optical fibers, and more particularly to an optical fiber sub-unit adapted to be mounted on a rack.
BACKGROUND
With the growth of fiber optic communication systems, various devices have been developed to house and manage complex assemblies associated with fiber optic communication. For example, existing optical fiber sub-units have multiple modules mounted over a slidable tray. In case one of the modules of the multiple modules require maintenance, a user has to slide out the entire tray assembly.
For example, a prior art reference “US8712206B2” disclosed a plurality of fiber modules mounted on a tray. The tray is slidably mounted on a chassis and each of the module can be accessed by sliding out corresponding tray. Another prior art reference “US10094996B2” discloses a plurality of fiber modules mounted on a tray. The tray is slidably mounted on a chassis and each of the module can be accessed by sliding out corresponding tray. Also, each of the fiber module can be individually slidable by using guide rails over the tray. Yet another prior art reference “US10859782B2” discloses a fiber enclosure with a movable tray and cable manager to arrange the patch cords of the fiber enclosure. However, each of the above stated prior arts does not enable a user to extract a single module from the sub-unit for maintenance. Moreover, there remains a continuing need for improvements to lower cost, increase efficiency and provide for ease maintenance of the optical fiber sub-units.
Thus, there is a need to develop an optical fiber sub-unit that overcomes the aforementioned technical disadvantages of the traditional optical fiber sub-units.
SUMMARY
In an aspect of the present disclosure, an optical fiber sub-unit is disclosed. The optical fiber sub-unit is adapted to be mounted on a rack. The optical fiber sub-unit has a plurality of walls substantially parallel to each other such that a wall of the plurality of walls separated from an adjacent wall of the plurality of walls forms a plurality of chambers. Each chamber of the plurality of chambers is adapted to receive a plurality of fiber optic modules such that each chamber of the plurality of chambers the plurality of fiber optic modules in an XY plane.

DETAILED DESCRIPTION
The detailed description of the appended drawings is intended as a description of the currently preferred aspects of the present disclosure, and is not intended to represent the only form in which the present disclosure may be practiced. It is to be understood that the same or equivalent functions may be accomplished by different aspects that are intended to be encompassed within the spirit and scope of the present disclosure.
FIG. 1A illustrates a perspective view of an optical fiber sub-unit 100. The optical fiber sub-unit 100 may be adapted to be mounted on a rack unit (not shown) of a data centre. Specifically, the optical fiber sub-unit 100 may have a trayless design with one or more partition walls. It provides easy access to an individual optical fiber module and hence, other modules will remain undisturbed. The optical fiber sub-unit 100 may have a plurality of walls 102 and a base 104. The plurality of walls 102 may have a plurality of side walls 102a and one or more partition walls 102b. The one or more partition walls 102b may be disposed between two opposing side walls of the plurality of side walls 102a. As illustrated, the plurality of side walls 102a may have first and second side walls 102aa and 102ab and the one or more partition walls 102b may have first through third partition walls 102ba-102bc. Specifically, the first through third partition walls 102ba-102bc may be disposed between the first and second side walls 102aa and 102ab. In some aspects of the present disclosure, the first through third partition walls 102ba-102bc and the first and second side walls 102aa and 102ab may be parallel to each other. Although FIG. 1A illustrates that the one or more partition walls 102b have 3 walls (i.e., the first through third partition walls 102ba-102bc), it will be apparent to a person skilled in the art that the scope of the present disclosure is not limited to it. In various other aspects of the present disclosure, the one or more partition walls 102b may have any number of partition walls, without deviating from the scope of the present disclosure. In such a scenario, each partition wall is configured to perform one or more operations in a manner similar to the operations of the first through third partition walls 102ba-102bc as described herein.
In some aspects of the present disclosure, each partition wall of the plurality of partition walls 102b may have a pair of walls 106 coupled in a back to back configuration.

Further, the first and second attachment walls 108a and 108b may have seventh and eighth set of guide rails 110g and 110h (as shown in FIGs 1A and 1B). In other words, the first side wall 102aa and the second side wall 102ab may have the set of guide rails 110 (i.e., the seventh and eighth set of guide rails 110g and 110h) by virtue of the first and second attachment walls 108a and 108b on at least one surface. As illustrated, a wall of the plurality of walls 102 separated from an adjacent wall of the plurality of walls 102 forms a plurality of chambers 112.

Each pair of adjacent walls of the plurality of walls 102 may be disposed at a distance (D) from one another. For example, the first partition wall 102ba and the second partition wall 102bb may be disposed at the distance (D) from one another. In some aspects of the present disclosure, the distance (D) may be in a range of 90 mm to 100 mm. Preferably, the distance (D) may be 91.45 mm. In other words, the distance (D) between adjacent walls of the plurality of walls 102 may be in the range of 90 mm to 100 mm. In some aspects of the present disclosure, each partition wall of the one or more partition walls 102b (i.e., the first and second partition walls 102ba and 102bb) may have a thichness (T) that may be in a range of 15 mm to 19 mm. Preferably, the thichness (T) may be 17.4 mm. In some aspects of the present disclosure, each chamber of the plurality of chambers 112 (e.g., the chamber 112a) may have a chamber width (CW) that may be in a range of 125 mm to 128 mm. Preferably, the chamber width (CW) may be 126.25 mm.
Thus, the optical fiber sub-unit 100 of the present disclosure facilitates in elimination of additional support members and/or components that are required in traditional optical fiber sub-units to hold the fiber optic modules within the optical fiber sub-units. Further, the top cover 126 being a removable cover and the rear door 128 and the front door 130 being openable doors, provides easy access to the the optical fiber sub-unit 100 for assembling. Furthermore, as the fiber optic module 114a is slidable and accessible inside the optical fiber sub-unit 100, hence, there is no need to disturb other fiber optic modules while working on a selected one. As each of the fiber optic modules are arranged between the plurality of partition walls 102b, there is no requirements to add any other support member such as, a base tray, and the like.
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. , C , C , Claims:I/We Claim(s):
