Description

Technical Field

[0001] This invention relates to the technical field of fiber optic transmission in data center micro-module DC compartments, and specifically to a fiber optic patch panel and cabling method for micro-module DC compartments. Background Technology

[0002] Existing traditional data centers can no longer meet the development needs of 5G services. A new generation of data centers is needed that can not only meet the needs of existing broadband access but also support the development of interactive digital television and various value-added services. Data centers will become the mainstay for the in-depth promotion of triple-play services and the reliable operation of cross-network services.

[0003] The data center micro-module (DC) cabin mainly consists of three parts: a basic high-speed IP network, an application server cluster, and a storage system. The micro-module DC cabin enables the integration and unified management of content resources within the network, compensating for broadband service shortcomings and improving the broadband user experience through technologies such as mirroring and caching.

[0004] Traditional network structures result in both centralized and decentralized services. Data center networks providing high-quality video and information services to end users also need to consider interfacing with metropolitan area networks (MANs) and user-level access networks. Furthermore, many local access networks supporting video-on-demand services require the construction of distribution networks (CDNs). Therefore, the construction of micro-module data center (DC) networks faces three major challenges: First, the data center serves all distributed front-end users. To eliminate the impact of latency and congestion between distributed front-ends and the central front-end on interactive video services, multiple secondary core devices of the city's distributed front-ends can be directly connected to the cloud platform's data center switches. This approach typically occurs in the early stages of project construction and in provincial capitals. Second, a CDN-like network structure can be implemented, with a central node distributing content to the city-level distributed front-end data center server rooms via fiber optic channels. Users first access the distributed front-end data center network. Third, a fully distributed structure can be adopted, where each distributed front-end data center independently provides services to users, and CDN technology is used to achieve content distribution and synchronization between distributed front-ends, requiring both dispersion and convergence.

[0005] Therefore, cloud data centers face challenges such as rapidly expanding network scale and an excessive amount of fragmented user data. Big data services require the fusion and analysis of large amounts of fragmented, unstructured data from different perspectives. Simultaneously, data center footprints are limited, optical routing switching is difficult, and core switches directly connect to multiple secondary core node switches in the metropolitan area network. It is necessary to shorten the path for users to access the cloud service platform and reduce backbone network traffic pressure. Furthermore, top-of-rack TOR switches and dual-core switches need to be interconnected synchronously, virtualizing two physically independent switches into a logically unified single switch. How to achieve rapid fiber optic access, low investment, and quick results while providing efficient and high-quality information services to the public has become a crucial problem to be solved.

[0050] [First Embodiment]

[0051] like Figure 1 The image shows a fiber optic distribution frame for a micro-module DC compartment provided by the first embodiment of the present invention, including a rack 1, a fiber optic cable stripping and fixing unit 2, a fusion splicing tray 3, a fiber coiling and storage unit 4, a wiring unit 5, a vertical wiring channel 6, and a horizontal wiring trough 7; wherein, the fiber optic cable stripping and fixing unit 2 is disposed on the top of the rack 1, and the fusion splicing tray 3 and the wiring unit 5 are disposed sequentially from top to bottom on the rack 1 and at the bottom of the fiber optic cable stripping and fixing unit 2, the fusion splicing tray 3 and the wiring unit 5 are disposed at the bottom of the fusion splicing tray 3 and the wiring unit 5 respectively, the vertical wiring channel 6 is disposed on one side of the fusion splicing tray 3 and the wiring unit 5, and the horizontal wiring trough 7 is disposed at the bottom of the bottom fiber coiling and storage unit 4.

[0052] The cabling method in this embodiment is as follows: the outdoor optical fiber 8 enters from one side of the top of the rack 1, is fixed by the optical cable stripping and fixing unit 2, and then enters the fusion splicing tray 3 to be spliced ​​with the optical fiber patch cord 9; the optical fiber patch cord 9 enters from the other side of the top of the rack 1, enters the fiber storage unit 4 through the vertical routing channel 6 set on one side of the fusion splicing tray 3 to store redundant optical cables, and then enters the fusion splicing tray 3 to be spliced ​​with the outdoor optical fiber 8.

[0053] This embodiment uses the shortest cabling path to weld the outdoor optical fiber 8 and the optical fiber patch cord 9 together, saving cabling path length and cabling space. Both the outdoor optical fiber 8 and the optical fiber patch cord 9 are located at the top of the rack 1, making cabling convenient and quick. They can be used independently or in combination, with a wide range of applications and convenient and fast connection.

[0054] [Second Embodiment]

[0055] like Figure 2-3 The image shows a fiber optic distribution frame for a micro-module DC compartment provided by the second embodiment of the present invention, comprising: a frame 1, a fiber optic cable stripping and fixing unit 2, a fusion splicing tray 3, a fiber coiling and storage unit 4, a wiring unit 5, a vertical wiring channel 6, and a horizontal wiring groove 7; wherein, the fiber optic cable stripping and fixing unit 2 is disposed on the top of the frame 1, and differs from the first embodiment in that: the top fusion splicing tray 3, the wiring unit 5, and the bottom fusion splicing tray 3 are arranged sequentially from top to bottom on the frame 1 and at the bottom of the fiber optic cable stripping and fixing unit 2, and the fiber coiling and storage unit 4 is disposed at the bottom of the fusion splicing tray 3 and the wiring unit 5 respectively; a vertical wiring channel 6 is disposed on one side of the fusion splicing tray 3 and the wiring unit 5, and a horizontal wiring groove 7 is disposed at the bottom of the bottom fiber coiling and storage unit 4.

[0056] This embodiment, by providing a top integrated welding tray 3, a wiring unit 5, and a bottom integrated welding tray 3, facilitates the simultaneous entry of cables from the top and bottom of the frame 1 for welding.

[0057] In this embodiment, the fiber optic patch panel can be used as either a fiber fusion splice frame 13 or a fiber distribution frame 14.

[0058] like Figure 2 As shown, when the fiber optic distribution frame is used as a fusion splice rack 13, the outdoor fiber optic cable 8 enters from the top side of the rack 1, is fixed by the fiber optic cable stripping and fixing unit 2, and then enters the top fusion splice tray 3 to be fused with the fiber optic patch cord 9. The fiber optic patch cord 9 enters from the bottom side of the rack 1, passes through the bottom fusion splice tray 3 and the vertical routing channel 6 set on one side of the distribution unit 5, enters the fiber storage unit 4 to store redundant fiber optic cable, and then enters the top fusion splice tray 3 through the vertical routing channel 6 on one side of the top fusion splice tray 3 to be fused with the outdoor fiber optic cable 8. At this time, the connection and wiring between the outdoor fiber optic cable 8 and the fiber optic patch cord 9 can be realized through the fusion splice rack 13.

[0059] like Figure 3As shown, when the fiber optic distribution frame is used as the fiber distribution rack 14, the fiber optic patch cord 9 enters from one side of the bottom of the rack 1, passes through the bottom integrated fusion splicing tray 3, the distribution unit 5, and the vertical routing channel 6 on one side of the top integrated fusion splicing tray 3, and is spliced ​​to the multi-core optical cable 10. The multi-core optical cable 10 enters from the other side of the bottom of the rack 1, stores redundant optical cables through the fiber coil storage unit 4, and then enters the top integrated fusion splicing tray 3 to be spliced ​​to the fiber optic patch cord 9. At this time, the connection and wiring between the multi-core optical cable 10 and the fiber optic patch cord 9 can be realized through the fiber distribution rack 14. In this embodiment, the multi-core optical cable 10 is an MPO multi-core pre-terminated multi-core optical cable 10.

[0060] Combination Figure 2 and Figure 3 Since both involve the connection of fiber optic patch cords 9, the connection between the fiber optic patch cord 13 and the fiber distribution frame 14 can be achieved through the fiber optic patch cords 9.

[0061] In this embodiment, as Figure 5 As shown, fiber optic distribution frames can be selected from combinations of multiple fusion splice frames, such as... Figure 4 As shown in 6-7, a combination of a fiber melting rack and a fiber distribution rack can also be used.

[0062] like Figure 5 As shown, when multiple fusion splice racks are used in combination for the fiber optic distribution frame, the fiber optic patch cords 9 at the bottom of the rack 1 of adjacent fusion splice racks are interconnected. For example... Figure 4 and 6 As shown in Figure 7, when the fiber optic distribution frame is a combination of a fusion splice frame and a fiber distribution frame, the fiber optic patch cords 9 at the bottom of the rack 1 of adjacent fusion splice frames and fiber distribution frames are interconnected, and the multi-core optical cables 10 at the bottom of the rack 1 of adjacent fiber distribution frames are interconnected.

[0063] like Figure 4The diagram shows a structural schematic of a single fusion splicing rack and a single distribution rack used in combination. In this embodiment, the outdoor optical fiber 8 enters from the top of the rack 1 of the fusion splicing rack 13, is fixed by the optical cable stripping and fixing unit 2, enters the top fusion splicing tray 3 for splicing and termination, connects to the optical fiber patch cord 9, and passes through the fiber coiling and storage unit 4 to store redundant optical cable. Then, it enters the horizontal cable tray 7 downward through the vertical cable routing channel 6, exits the rack 1 of the fusion splicing rack 13, connects to the rack 1 of the distribution rack 14, and enters the top fusion splicing tray 3 through the vertical cable routing channel 6 of the distribution rack 14. The multi-core optical cable 10 coming from the other side of the equipment passes through the fiber coiling and storage unit 4 of the distribution rack 14 to store redundant optical cable, enters the top fusion splicing tray 3 for splicing and termination, and connects to the terminal port of the optical fiber patch cord 9, completing the termination and distribution of the optical link. The advantage of this wiring method is that the connection between the outdoor optical fiber 8 and the multi-core optical cable 10 can be achieved by connecting and cooperating a single fiber fusion splice frame 13 and a single fiber distribution frame 14, while the single fiber fusion splice frame 13 and the single fiber distribution frame 14 are connected by optical fiber patch cords 9.

[0064] like Figure 5 The diagram shows a structural schematic of multiple fiber optic splicing racks used in combination according to the present invention. After four fiber optic splicing racks 13 are mounted side by side, outdoor optical fibers 8 enter from the top of the rack 1 of the splicing rack 13, are fixed by the optical cable stripping and fixing unit 2, and are spliced ​​and terminated in the top integrated splicing and distribution tray 3. They are then connected to optical fiber patch cords 9, and after passing through the fiber storage unit 4 to store redundant optical cables, they pass through the vertical cabling channel 6 and enter the horizontal cabling groove 7, exiting the rack and connecting to another terminal port. The terminal ports of the four fiber optic splicing racks can be directly connected to each other or cross-connected to each other, completing the termination, distribution, direct connection, and cross-connection of the optical link. The advantage of this cabling method is that it can achieve one end to be connected to multiple outdoor optical fibers 8, while the other end is connected only through one optical fiber patch cord 9.

[0065] like Figure 6The diagram shows a structural schematic of the alternating combination of the fiber fusion splicing rack and the fiber distribution rack of the present invention. In this embodiment, after the racks are combined, the external cable 8 enters from the top of the rack 1 of the fiber fusion splicing rack 13, is fixed by the optical cable stripping and fixing unit 2, enters the top integrated fusion and distribution tray 3, is spliced ​​and terminated, and then connects to the optical fiber patch cord 9. After passing through the fiber coiling and storage unit 4 to store redundant optical cables, it enters the horizontal cable tray 7 through the vertical cable routing channel 6, exits the rack and enters the top integrated fusion and distribution tray 3 of another fiber distribution rack 14. Meanwhile, the multi-core optical cable 10 from the equipment side enters the fiber distribution rack 14, passes through the fiber coiling and storage unit 4 to store redundant optical cables, enters the top integrated fusion and distribution tray 3 and is spliced ​​and terminated with the optical fiber patch cord 9 from the fiber fusion splicing rack 13, thus achieving the connection with the optical fiber patch cord 9 from the fiber fusion splicing rack, completing the termination, distribution and wiring of the optical link, direct connection and cross connection. The advantage of this wiring method is that it ensures that the number of connections to multiple outdoor optical fibers 8 at one end is consistent with the number of connections to multi-core optical cables 10 at the other end, which is beneficial to the stability of input and output power and also facilitates line troubleshooting.

[0066] like Figure 7 The diagram shows a structural schematic of a single fiber fusion splicing rack combined with multiple fiber distribution racks according to the present invention. Outdoor optical cables 8 enter from the top of the rack 1 of the fiber fusion splicing rack 13, are fixed by the optical cable stripping and fixing unit 2, and are spliced ​​into the top integrated splicing and distribution tray 3. They then connect to fiber optic patch cords 9, pass through the fiber coiling and storage unit 4 to store redundant optical cables, and then pass downwards through the vertical routing channel 6 into the horizontal routing groove 7. Finally, they exit the rack and enter the top integrated splicing and distribution tray 3 of another fiber distribution rack 14. Multi-core optical cables 10 from the equipment side enter the fiber distribution rack 14, pass through the fiber coiling and storage unit 4 to store redundant optical cables, and then enter the top integrated splicing and distribution unit 3 to be spliced ​​into the fiber optic patch cords 9 from the fiber fusion splicing rack 13 or the fiber optic patch cords 9 within the fiber distribution rack 14. This achieves connection with the fiber optic patch cords 9, completing the termination, distribution, direct connection, and cross-connection of the optical link. The advantage of this cabling method is that both ends of the rack can be a single outdoor optical cable 8 and a single multi-core optical cable 10, effectively avoiding potential interference between complex cables at the entry and exit points.

[0067] like Figure 8 As shown, in this embodiment, one end of the multi-core optical cable 10 is branched by a splitter 11, and the tail end is formed into multiple optical connectors 12 through a bonding, curing and polishing process. The optical connectors 12 can be any one or a combination of FC, SC, LC, MPO and APC, and their core count can reach 12, 24, 48, 72, 96 or 144 cores, etc.

[0068] like Figure 9The diagram shows the connection structure of the data center micro-module DC compartment, the fiber optic splicing rack, and the fiber distribution rack of the present invention. The outdoor optical fiber 8 enters the fiber optic distribution frame and is terminated by the fiber optic splicing rack 13. The fiber optic distribution frame 14 is connected to the data center micro-module DC compartment through the multi-core optical cable 10. The fiber optic splicing rack 13 and the fiber distribution rack 14 are connected by the fiber optic patch cord 9 to realize the interconnection of the micro-module DC compartment. The internal modules of the data center micro-module DC compartment are interconnected through the internal fiber optic patch cord 16. The fiber optic patch cord 9 and the internal fiber optic patch cord 16 can be any one or more combinations of FC / SC / LC / APC.

[0069] [Third Embodiment]

[0070] The third embodiment of the present invention also provides a cabling method for a fiber optic distribution frame for a micro-module DC compartment, comprising the following steps:

[0071] 1) Determine the types, quantities, and connection relationships of each module inside the data center micro-module (DC) compartment; and determine the types, quantities, and connection relationships of the internal optical jumpers 16 required for the connection between each module.

[0073] 3) Determine the type, quantity, and connection relationship of the optical connector 12 based on the type, quantity, and connection relationship of each module. One end of the multi-core optical cable 10 is connected to the optical connector 12 through the splitter 11.

[0074] 4) Outdoor optical fiber 8 enters from the top side of the frame 1 of the fusion splice rack 13, is fixed by the optical cable stripping and fixing unit 2, and then enters the top fusion splice tray 3 to be spliced ​​with optical fiber patch cord 9. One end of optical fiber patch cord 9 enters from the bottom side of the frame 1 of the fusion splice rack 13, passes through the bottom fusion splice tray 3 and the vertical routing channel 6 set on one side of the distribution unit 5, enters the fiber storage unit 4 to store redundant optical cable, and then enters the top fusion splice tray 3 through the vertical routing channel 6 on one side of the top fusion splice tray 3 to be spliced ​​with outdoor optical fiber 8. The other end of optical fiber patch cord 9 is connected to the fiber distribution rack 14.

[0075] 5) The other end of the fiber optic patch cord 9 enters from the bottom side of the rack 1 of the fiber distribution rack 14, and enters the fusion-distribution integrated tray 3 through the bottom fusion-distribution integrated tray 3, the distribution unit 5, and the vertical routing channel 6 on one side of the top fusion-distribution integrated tray 3 to be fused to the multi-core optical cable 10; one end of the multi-core optical cable 10 enters from the other side of the bottom of the rack 1 of the fiber distribution rack 14, and after storing redundant optical cables through the fiber coil storage unit 4, it enters the top fusion-distribution integrated tray 3 to be fused to the fiber optic patch cord 9; the other end of the multi-core optical cable 10 is connected to each module in the data center micro-module DC compartment 15 through the optical connector 12.

[0076] It will be apparent to those skilled in the art 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 its spirit or essential characteristics.
