Description

Technical Field

[0001] This application relates to the field of data transmission technology, and in particular to a speed distribution cabinet and data center. Background Technology

[0002] Traditional data center cabling often employs a combination of technologies such as LC-LC, optical modules, AOC (Active Optical Cable), DAC (Direct Connector), and MPO, which can, to a certain extent, meet the standard speed connection requirements of data centers. However, with the rapid development of information technology and the continuous advancement of industrial upgrading, traditional cabling methods have gradually exposed many limitations and challenges.

[0003] First, while LC-LC connections are widely used, the high cost of their required optical modules directly increases overall cabling costs. With the continuous expansion of data center scale and the increasing number of devices, high costs have become a significant factor restricting data center construction and operation. Second, AOC, as an active optical cable, offers high transmission rates, but its transmission distance is strictly limited, typically not exceeding 30 meters. Beyond this distance, the transmission bandwidth rate drops significantly, impacting the overall performance of the data center. Similarly, DAC, as a passive optical cable, has even stricter distance limitations, typically a maximum transmission distance of no more than 7 meters, which is particularly inconvenient in large data centers. Furthermore, while MPO connections can support high fiber density and port counts, their higher cost, higher failure rate, and relatively poor stability make their cost-effectiveness less prominent in data center cabling.

[0004] In conclusion, traditional data center cabling methods face significant challenges in terms of industry upgrading and expansion. High costs, strict transmission distance limitations, and low cost-effectiveness make traditional cabling methods unable to meet the current data center demands for high performance, scalability, and economy. Therefore, finding a more advanced, efficient, and economical cabling method has become an urgent problem to be solved in the field of data center construction and operation. Utility Model Content

[0033] See Figure 1 , Figure 1 This is a principle block diagram provided in the embodiments of this application, which will be combined with Figure 1 This application provides a speed distribution cabinet, which includes a connection module, an internal transmission module, and an output module.

[0034] The connection module is located at the front end of the speed distribution cabinet. The connection module is provided with at least one PSM4 optical module slot. The connection module is connected to the output end of the switch through the PSM4 optical module. The output end of the PSM4 optical module is connected to the input end of the internal transmission module.

[0035] The internal transmission module is installed inside the speed distribution cabinet. The internal transmission module is used to transmit the received data in the speed distribution cabinet. The output end of the internal transmission module is connected to the output module.

[0036] The output module is located at the rear end of the speed distribution cabinet, and the output module is connected to the input end of the uplink switch through a number of channels matching the PSM4.

[0037] The speed distribution cabinet mainly consists of three core modules: a connection module, an internal transmission module, and an output module.

[0038] The connection module is located at the front end of the speed distribution cabinet. Each connection module is equipped with at least one PSM4 optical module slot. Through these slots, the connection module can connect to the output of the switch using a PSM4 optical module. The PSM4 optical module is a high-speed, high-density optical interface suitable for large data transmission. The PSM4 optical module receives data from the switch and transmits it to the internal transmission module.

[0039] The internal transmission module is located inside the speed distribution cabinet. Its main task is to efficiently and stably transmit data received from the connection module within the cabinet. The internal transmission module receives data from the connection module and then transmits it to the output module.

[0040] The output modules are located at the rear of the speed distribution cabinet. They connect to the inputs of the uplink switch via a number of channels matching the PSM4. The output modules are designed to ensure efficient and compatible data transmission with the uplink switch. The output modules receive data from the internal transmission modules and transmit it to the uplink switch.

[0041] The above embodiments aim to achieve fast and stable data transmission between the speed distribution cabinet and external switches through an efficient modular structure. The connection module utilizes PSM4 optical modules for high-speed connection to the switches, the internal transmission module ensures efficient data transmission within the cabinet, and the output module enables further data transmission through a compatible connection with the uplink switch. This design guarantees both data transmission speed and quality while improving system flexibility and scalability.

[0042] In some embodiments, the transmission rates of the PSM4 optical modules in the at least one PSM4 optical module slot are different.

[0043] This embodiment offers greater flexibility and adaptability to meet the needs of different scenarios and applications.

[0044] Regarding the transmission rate of the PSM4 optical module, there are generally the following situations:

[0045] Standard transmission rate:

[0046] 100GPSM4 optical module: This is a common PSM4 optical module with a transmission rate of up to 100Gbps. It uses a single-mode fiber parallel transmission mode, and the data transmission rate of each channel can typically reach 25Gbps (in some cases it may be slightly higher, such as 26Gbps), with wavelengths of 850nm~1310nm and 1310nm~1550nm.

[0047] Rate adaptability at different transmission distances:

[0048] PSM4 optical modules not only have a fixed transmission rate, but their design also takes into account cost-effectiveness over different transmission distances. For example, some PSM4 optical modules are specifically designed for transmission distances of 500m to provide a cost-effective solution; while others may support longer transmission distances, such as 2km, but may require trade-offs in the number of optical fibers or cost.

[0049] Configurability: The design of the speed distribution cabinet provides PSM4 optical module slots with different transmission rates, allowing users to select the appropriate module according to their actual needs. For example, in scenarios requiring high-speed, long-distance transmission, PSM4 optical modules supporting higher transmission rates and longer transmission distances can be selected; while in scenarios with strict cost requirements, modules with lower costs and moderate transmission rates and distances can be selected.

[0050] Compatibility: PSM4 optical modules with different transmission rates should have good compatibility to ensure seamless integration into the speed distribution cabinet and operation with switches and other network devices. The optical modules should conform to the same industry standards or protocols (such as MSA) and have the same interface type and electrical characteristics.

[0051] In this configuration, at least one PSM4 optical module slot in the speed distribution cabinet supports PSM4 optical modules with different transmission rates, providing users with greater flexibility and adaptability. Users can select the appropriate module according to their actual needs to achieve optimal performance and cost-effectiveness. At the same time, this design also requires good compatibility between optical modules to ensure stable system operation.

[0052] In some embodiments, the transmission rate range of the PSM4 optical module is 10G-800G.

[0053] In some embodiments, the transmission rate of the PSM4 optical module includes at least 10G, 25G, 50G, 100G, 200G, 400G, and 800G.

[0054] Standard rates for PSM4 optical modules: PSM4 (Parallel Single Mode 4-lane) optical modules are typically designed to support high transmission rates, such as 25Gbps per channel (100Gbps for four channels). This is a typical and common configuration for PSM4 optical modules.

[0055] Non-standard rates: Although the PSM4 optical module supports a transmission rate of 100Gbps in the standard configuration, in some special cases, different transmission rates can be supported through technical improvements or custom design.

[0056] Specific speed points include 10G, 25G, 50G, 100G, 200G, 400G, and 800G, supported by different types of optical modules. For example, 10G and 25G speed modules are SFP or SFP+ type, while 100G speed modules are PSM4 or QSFP28 type. 200G, 400G, and 800G speed modules can use higher channel counts (such as PSM8, QSFP-DD, etc.).

[0057] In some embodiments, the internal transmission module uses an LC-LC interface for data transmission.

[0058] An LC connector is a type of fiber optic connector that uses a pluggable design and is characterized by its small size, ease of operation, and stable performance. An LC-LC connector refers to a fiber optic patch cord that uses LC connectors at both ends, typically used in applications requiring high-density, high-performance connections, such as data centers and communication networks.

[0059] The LC-LC interface provides a stable, low-loss fiber optic connection, ensuring efficient and accurate data transmission within the internal transmission module. LC-LC fiber optic patch cords using Class B connectors ensure ultra-low insertion loss and optimal return loss, effectively reducing the error rate and improving data transmission reliability. The compact size of the LC interface allows for more connection ports within limited space, meeting the needs of high-density applications. Inside a speed distribution cabinet, internal transmission modules using the LC-LC interface can utilize space more effectively, improving overall equipment performance and scalability. The pluggable design of the LC-LC interface makes connecting and disconnecting fiber optic patch cords simple and quick, reducing operational complexity and time costs. The LC-LC interface is one of the most widely used standard interfaces in the field of fiber optic communication, offering excellent compatibility. This means that internal transmission modules using the LC-LC interface can connect and communicate with a variety of different types of fiber optic equipment and networks.

[0060] In some embodiments, the number of uplink switches matches the number of channels, and the transmission rate of each uplink switch is the same as the transmission rate of a single channel.

[0061] In network architecture, uplink switches play a crucial role in transmitting data traffic from lower layers (such as the access layer) to higher layers (such as the core layer). To ensure efficient network operation, it is necessary to plan and configure the number and transmission rate of uplink switches appropriately.

[0062] In some embodiments, the number of uplink switches matches the number of channels. This means that each channel has a corresponding uplink switch to handle data traffic. This design ensures that data traffic on each channel is adequately processed and transmitted, avoiding bottlenecks and congestion. The transmission rate of each uplink switch is the same as the transmission rate of a single channel. This means that the performance of the uplink switches is consistent with the performance of the channels. This design ensures that data transmission between uplink switches and channels does not create performance bottlenecks due to rate mismatches.

[0063] In some embodiments, the output of the uplink switch is connected to the input of the top switch, which is used to connect to the server.

[0064] Here, the network architecture employs a specific connection pattern, where the output of the uplink switch is connected to the input of the top switch, which in turn connects to the server. This design is typically used to optimize data traffic, improve network performance and reliability, and simplify network management.

[0065] Uplink switches typically reside at lower layers of the network architecture (such as the access or aggregation layer), responsible for relaying traffic from clients or access devices upwards to higher-level switches or routers. In these embodiments, the output of the uplink switch is designed to connect to the top switch to transmit data traffic. The top switch, located at a higher layer of the network architecture (such as the core layer), typically offers higher performance and richer functionality. It connects servers, ensuring data communication between servers and connectivity between servers and external networks. In this embodiment, a direct connection is used between the uplink switch and the top switch. This connection may include fiber optic connections, Ethernet connections, or other high-speed connection technologies to ensure efficient data traffic transmission.

[0066] In some embodiments, the top switch is connected to the server via an AOC and / or a DAC.

[0067] In some embodiments, the transmission rate of the AOC and / or DAC is the same as the transmission rate of the uplink switch.

[0068] Here, the network architecture is designed using specific connection technologies and components to optimize data transmission and network performance. Specifically, the connection between the top-level switch and the server utilizes two high-performance connection cables: AOC (Active Optical Cable) and / or DAC (Direct Connect Copper Cable), and these cables have the same transmission rate as the uplink switch.

[0069] In this embodiment, the transmission rate of the AOC and / or DAC is the same as that of the uplink switch. This design ensures that data transmission between the uplink switch, connecting cables, and servers will not experience performance bottlenecks due to rate mismatch. Using AOC and / or DAC as the connecting cables between the top-level switch and the server ensures efficient data transmission. These high-performance connecting cables provide a low-loss, low-latency transmission path, thereby improving overall network performance. Both AOC and DAC offer good reliability and stability, ensuring stable connections and data communication between servers. Compared to optical modules, AOCs do not suffer from interface contamination, significantly improving system stability and reliability. Administrators can more easily monitor and manage network traffic and connection status, reducing maintenance costs.

[0070] In summary, the embodiments of this application have the following beneficial effects:

[0071] (1) Significantly improved data transmission efficiency: The speed-matching cabinet significantly improves data transmission efficiency by integrating high-performance PSM4 optical modules and optimized internal transmission modules. This design enables high-speed and stable data transmission between the inside and outside of the cabinet, thereby improving the overall performance and response speed of the data center.

[0072] (2) Flexible adaptation to different transmission rate requirements: The speed matching cabinet provides PSM4 optical module slots with multiple transmission rates, which can flexibly adapt to the transmission rate requirements of different business scenarios. This flexibility allows the cabinet to select the most suitable transmission rate according to different application scenarios and performance requirements, thereby improving resource utilization and cost-effectiveness.

[0073] (3) Simplified network architecture and reduced complexity: The speed distribution cabinet simplifies the network architecture and reduces complexity by seamlessly integrating uplink switches and top switches.

At the same time, the integrated design and standardized interfaces of the cabinet also simplify network management and maintenance, reduce operation and maintenance costs, and improve operational efficiency.

[0075] This application also provides a data center, which includes at least one speed-matching cabinet provided in this application embodiment, and the data center transmits data through the speed-matching cabinet.

[0076] This data center design solution, which includes speed-matching cabinets, is suitable for various application scenarios requiring high performance, high reliability, and scalability, such as cloud computing platforms, big data analytics centers, and enterprise data centers. These scenarios have extremely high requirements for data transmission speed, capacity, and reliability, and the data center design solution using speed-matching cabinets can meet these needs and provide excellent business support and services.
