Description

Technical Field

[0001] This invention relates to the field of fiber optic distribution frame technology, and specifically to a high-capacity fiber optic distribution frame. Background Technology

[0002] Fiber optic distribution frames (ODFs) are wiring connection devices between optical cables and optical communication equipment or between optical communication equipment. They are used for termination and distribution of the main optical cables at the central office in optical fiber communication systems, and can facilitate the connection, distribution and scheduling of optical fiber lines.

[0003] Traditional fiber optic distribution frames have a layout where the left side houses the patch cord storage area, the right side is the cable bundling and fixing area, the top center is the cable entry stripping and fixing area, and the bottom is the fiber optic fusion splice unit installation area. Each fiber optic fusion splice unit has a capacity of 72 cores (6 integrated 12-core panels, with commonly used FC or SC type adapters), and the unit height is 4U. A 2.2-meter fiber optic distribution frame can only accommodate 8 sets of 72-core fiber optic fusion splice units, for a total capacity of only 576 cores. This design suffers from small rack capacity, low room space utilization, and the fact that both rack storage and fiber optic fusion splice unit outputs are on the left side, requiring cross-operation and causing fiber congestion, which is detrimental to fiber management. Furthermore, because of the single-sided storage, the other side must be bundled for better fixation, but overly tight bundling can easily cause fiber breakage, resulting in patch cord breakage or high optical loss leading to line failure, posing numerous quality and safety hazards. Therefore, it is necessary to develop and design high-capacity fiber optic distribution frames to achieve left and right lateral accommodation of fiber optic distribution units, avoiding fiber crossing and congestion. This is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a high-capacity fiber optic distribution frame that enables the left and right accommodating of fiber optic distribution units, thereby avoiding fiber crossing and congestion.

[0005] To achieve the above objectives, the present invention provides the following solution: A high-capacity fiber optic distribution frame includes a fiber optic distribution frame body, at least three distribution modules arranged from top to bottom on the front of the fiber optic distribution frame body, mounting plates on both sides of the fiber optic distribution frame body, a receiving assembly on the mounting plates located on the front of the fiber optic distribution frame body, at least two optical cable entry and stripping units arranged from top to bottom on the back of the fiber optic distribution frame body, and a cable guard ring on the mounting plates located on the back of the fiber optic distribution frame body. The receiving assembly and the cable guard ring are at least three in number and arranged from top to bottom.

[0006] Preferably, the wiring module includes a cable management frame and three optical fiber splicing units arranged from top to bottom on the cable management frame.

[0007] Preferably, the wiring module has a height of 1U and a width of 19 inches.

[0008] Preferably, the fiber optic fusion splicing unit has 96 cores, and the wiring module has 12 cores.

[0009] Preferably, the optical fiber fusion splicing unit adopts a pull-out structure.

[0010] Preferably, the patch cords of the fiber optic fusion splicing unit located near the left side of the fiber optic distribution frame are received by the receiving assembly located on the left side of the fiber optic distribution frame, and the patch cords of the fiber optic fusion splicing unit located near the right side of the fiber optic distribution frame are received by the receiving assembly located on the right side of the fiber optic distribution frame.

[0011] Preferably, the receiving assembly has waist holes on both sides, and self-adhesive tape is inserted inside the waist holes for organizing the loose fibers.

[0012] Preferably, there are two optical cable introduction stripping units, and the optical cable introduced through the upper optical cable introduction stripping unit and the optical cable introduced through the lower optical cable introduction stripping unit are respectively fixed by the guard rings located on both sides.

[0013] Preferably, the optical fiber fusion splicing unit is provided with a pigtail, one end of which is fused to the optical cable fixed by the guard ring, and the other end of which is connected to a jumper fiber housed by the housing assembly.

[0014] Preferably, the jumper fiber and the pigtail fiber are connected via a full-duplex LC adapter.

[0015] The present invention achieves the following technical effects compared to the prior art: By setting up receiving components on both sides of the front of the fiber optic distribution frame, setting up at least two optical cable entry and stripping units in the middle of the back, and setting up cable guard rings on both sides of the back, a brand-new layout of front and rear operation separation and left and right symmetrical fiber routing is achieved. Patch cords and optical cables are diverted and received in independent front and rear channels, effectively avoiding cross-operation and congestion. This not only makes fiber routing smoother and provides more sufficient receiving space, but also reduces the risk of fiber breakage and signal attenuation. It achieves significant advantages such as large capacity, modularity, standardization, flexible configuration, and convenient construction. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a high-capacity fiber optic distribution frame that enables the left and right accommodating of fiber optic distribution units, avoiding fiber crossing and congestion.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] refer to Figure 1-5The high-capacity fiber optic distribution frame disclosed in this embodiment of the invention includes at least a fiber optic distribution frame body 1. At least three distribution modules are arranged on the front of the fiber optic distribution frame body 1, with the modules arranged sequentially from top to bottom. Mounting plates 7 are provided on both sides of the fiber optic distribution frame. A receiving assembly 2 is provided on the mounting plate 7 on the front of the fiber optic distribution frame body 1. The receiving assembly 2 is used to receive the jumpers 8 led out from the distribution modules. At least two fiber optic stripping units are provided on the back of the fiber optic distribution frame body 1, arranged sequentially from top to bottom. A cable guard ring 6 is provided on the mounting plate 7 on the back of the fiber optic distribution frame body 1. The fiber optic cable 9 introduced through the fiber optic stripping unit is fixed. The guard ring 6 and the housing assembly 2 are set to at least three and arranged from top to bottom. By setting the housing assembly 2 on both sides of the front of the fiber optic distribution frame 1, setting at least two fiber optic cable stripping units 5 in the middle of the back side, and setting the guard ring 6 on both sides of the back side, a new layout of front and rear operation separation and left and right symmetrical fiber routing is realized. The jumper 8 and the fiber optic cable 9 are diverted and housed in independent channels at the front and rear, which effectively avoids cross operation and congestion. This not only makes fiber routing smoother and provides more housing space, but also reduces the risk of fiber breakage and signal attenuation. It has achieved significant advantages such as large capacity, modularity, standardization, flexible configuration and convenient construction.

[0022] refer to Figure 1 In one embodiment, the wiring module includes a cable management frame 4 and three fiber optic fusion splicing units 3 arranged from top to bottom on the cable management frame 4. The wiring module, consisting of one horizontal fiber optic cable management frame 4 and three fiber optic fusion splicing units 3 arranged from top to bottom, is centrally arranged on the front of the fiber optic wiring frame 1. The cable management frame 4 uniformly collects, distributes, and guides the jumpers 8 of the three fusion splicing units in each module. After the jumpers 8 are led out from the fusion splicing units, they are first organized by the cable management frame 4 and then distributed to the left and right to the receiving area, avoiding the tangling and mess caused by the direct dispersion of multiple jumpers 8.

[0023] As one implementation method, the wiring module has a height of 1U (1U = 1.75 inches = 44.45 mm) and a width of 19 inches. It adopts a standardized size design with a height of 1U and a width of 19 inches, which realizes a high-density modular combination.

[0024] refer to Figure 1 As a preferred approach, the fiber optic fusion splicing unit 3 is a 96-core high-density duplex LC fiber optic fusion splicing unit. The wiring module, consisting of one fiber horizontal cable management frame 4 and three 96-core high-density duplex LC fiber optic fusion splicing units 3 arranged from top to bottom, is centrally arranged on the front of the fiber optic distribution frame 1. Each wiring module contains three fusion splicing units with a total of 288 cores, achieving an ultra-high density modular combination.

[0025] refer to Figure 1 As a preferred approach, the wiring module is set to 12, with a total capacity of 3456 cores (about 6 times that of the traditional 576 cores), which greatly improves the utilization rate of the data center space.

[0026] refer to Figure 1 As one implementation method, the patch cords 8 of the fiber optic fusion splicing unit 3 near the left side of the fiber optic distribution frame 1 are received by the receiving component 2 located on the left side of the fiber optic distribution frame 1, and the patch cords 8 of the fiber optic fusion splicing unit 3 near the right side of the fiber optic distribution frame 1 are received by the receiving component 2 located on the right side of the fiber optic distribution frame 1. They are uniformly gathered by the cable management rack 4, and follow the symmetrical fiber routing rule of receiving the patch cords 8 of the left fusion splicing unit from the left receiving component 2 and the patch cords 8 of the right fusion splicing unit from the right receiving component 2, so as to achieve the shortest path of patch cords 8 without crossover and splitting. Combined with the separation of front and back operation and the central arrangement, while achieving a standard rack capacity of 3456 cores, it ensures smooth fiber routing, orderly reception and high space utilization.

[0027] refer to Figure 1 As one implementation method, the housing assembly 2 has waist holes on both sides, and self-adhesive tape is inserted inside the waist holes. The self-adhesive tape is used to organize the jumper 8. After the jumper 8 is coiled, it can be quickly tied and fixed by the self-adhesive tape, which not only ensures that the arrangement is neat and not loose, but also facilitates disassembly and adjustment during maintenance, avoiding the problems of damage to optical fibers or non-reusability of traditional cable ties.

[0028] refer to Figure 1 As one implementation method, two optical cable entry stripping units 5 are set up. The optical cable 9 introduced through the upper optical cable entry stripping unit 5 and the optical cable 9 introduced through the lower optical cable entry stripping unit 5 are respectively fixed by the guard rings 6 located on both sides. By setting up two optical cable entry stripping units 5, and fixing the upper and lower optical cables 9 by the guard rings 6 on the left and right sides respectively, the balanced entry of optical cables 9 from top to bottom and the splitting from left to right are realized. This avoids the construction congestion and fixing difficulties caused by the concentrated stacking of optical cables 9, and improves the orderliness and operation convenience of the optical cable 9 routing on the back of the optical fiber distribution frame 1.

[0029] It should be noted that the fiber optic distribution frame 1 has a symmetrical structure on both the front and back. The front side facilitates the distribution and collection of fiber jumpers 8, while the back side facilitates the even bundling, fixing, and stripping of optical cables 9.

[0030] refer to Figure 1As one implementation method, the fiber optic fusion splicing unit 3 is equipped with a pigtail. One end of the pigtail is fused to the optical cable 9, which is fixed by the guard ring 6, and the other end of the pigtail is connected to the jumper 8, which is housed by the housing assembly 2. This establishes a complete, orderly, and maintainable fiber optic connection link between the front and back of the fiber optic distribution frame 1, enabling the optical cable 9 to be connected to the fiber optic equipment for service activation through the wiring and splicing of the fiber optic distribution frame 1.

[0031] As one implementation method, the fiber optic fusion splicing unit 3 adopts a pull-out structure. When it is necessary to perform fusion splicing of the optical cable 9, the fusion splicing unit can be pulled forward from the optical fiber distribution frame 1 to expose the fusion splice tray at the rear for operation. After the fusion splicing is completed, it is pushed back to its original position and fixed, which not only provides sufficient operating space for the fusion splicing operation, but also effectively protects the optical fiber of the fused optical cable 9 to avoid accidental contact damage.

[0032] It should be noted that metal guide rails are fixedly installed on both sides of the 19-inch equipment installation area on the front of the fiber optic distribution frame 1. The guide rails extend along the depth direction of the fiber optic distribution frame 1. Slider blocks are correspondingly provided on both sides of the fiber optic fusion splicing unit 3. The sliders are embedded in the guide rails and can slide back and forth along the guide rails. When fiber optic fusion splicing is required, the fiber optic fusion splicing unit 3 is pulled forward to expose the splice tray at its rear. After the fusion splicing and fiber coiling are completed, the fiber optic fusion splicing unit 3 is pushed back and locked in place by the limiting buckle set at the end of the guide rail, so that the unit is stably kept in the fiber optic distribution frame 1. The pull-out mechanism is also provided with an anti-drop-out limiting structure to prevent the unit from being pulled out too much and sliding out of the fiber optic distribution frame 1.

[0033] In one implementation, jumper 8 and pigtail are connected via a full-duplex LC adapter (flange). Jumper 8 is inserted into the other side of the full-duplex LC adapter, thus achieving a plug-and-play connection between the pigtail and jumper 8. This connection method is a standardized high-density interface, which is convenient to plug and unplug, has reliable contact, low optical loss, and supports flexible patching and scheduling.

[0034] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
