Technical Field
[0001] The utility model relates to the technical field of optical signal transmission, in particular to a multi-combination optical signal transmission device. Background Technique
[0002] In modern high-speed communication networks, with the explosive growth of data traffic, the requirements for transmission bandwidth and efficiency are increasing day by day. Traditional optical signal transmission systems often use a single wavelength or a limited number of wavelengths for data transmission, which is unable to cope when facing application scenarios such as large-scale data center interconnection, cloud computing services, and high-definition video transmission. To overcome these limitations, multi-wavelength and high-density optical signal transmission technologies have become a research hotspot.
[0003] However, in actual deployment, directly using high-density multi-wavelength light sources for long-distance transmission faces many challenges, such as dispersion, nonlinear effects, optical power attenuation, etc., which will seriously affect the transmission quality and distance of signals. In addition, how to effectively manage and schedule multiple optical signal sources to ensure their efficient and stable collaborative work is also an urgent problem to be solved.
[0004] To solve the above problems, various types of optical modules have emerged on the market. Among them, the 100G-QSFP28 optical module has become the mainstream choice in high-speed data transmission due to its advantages such as high bandwidth, low power consumption, and easy integration. However, although a single 100G-QSFP28 optical module has excellent performance, it is still unable to cope when facing ultra-large-scale data transmission requirements. Therefore, how to effectively combine multiple 100G-QSFP28 optical modules to achieve parallel processing and transmission of optical signals has become an important direction to improve the overall transmission capacity. Summary of the Utility Model
[0005] In view of this, the utility model provides a multi-combination optical signal transmission device, which can solve the defect that a single 100G-QSFP28 optical module is still unable to cope when facing ultra-large-scale data transmission requirements in the prior art.
[0006] The technical solution of the utility model is realized as follows:
[0007] A multi-combination optical signal transmission device includes two or more 100G-QSFP28 optical modules, a main control module, and a multiplexer / demultiplexer module. Each 100G-QSFP28 optical module is used to receive an externally input 100G optical signal, convert it into an electrical signal, and then convert it into a new 100G optical signal for output. The main control module is used to set the relevant parameters of the 100G-QSFP28 optical module, and real-time monitor and report the relevant data of each 100G-QSFP28 optical module. The multiplexer / demultiplexer module is used to combine the optical signals output by multiple 100G-QSFP28 optical modules into one or more paths for long-distance transmission, or demultiplex the received optical signal and distribute it to each 100G-QSFP28 optical module for processing.

This is of great significance for application scenarios that require processing large-scale data traffic. The design of the multiplexer / demultiplexer module enables the device to flexibly combine or demultiplex multiple optical signals, which means that during transmission, the transmission path and quantity of optical signals can be dynamically adjusted according to actual needs, thereby improving the flexibility and adaptability of the device. Each 100G-QSFP28 optical module has high-speed optoelectronic conversion capabilities, capable of quickly converting the received optical signals into electrical signals for processing and then converting them back into optical signals for output. This efficient conversion mechanism reduces signal processing latency and improves transmission efficiency. The main control module is responsible for setting the relevant parameters of the 100G-QSFP28 optical modules and real-time monitoring of their working status and data.

At the same time, the main control module can also report the monitored data to the upper-level management system, providing strong support for the operation and maintenance and optimization of the system. By integrating multiple optical modules and achieving parallel processing, the device can automatically adjust the transmission path when a single optical module fails, avoiding the impact of single-point failures on the entire device. In addition, the real-time monitoring function of the main control module also helps to promptly detect and isolate faulty modules, thereby improving the overall reliability of the device. Since the device realizes the centralized processing and transmission of optical signals, it reduces the dependence on physical lines and equipment, simplifies the wiring complexity and maintenance difficulty. At the same time, the intelligent management method also reduces the need for manual intervention and lowers the operation and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0018] Referring to Figures 1 to 3 , a multi-combination optical signal transmission device includes two or more 100G-QSFP28 optical modules, a main control module, and a multiplexing / demultiplexing module. Each of the 100G-QSFP28 optical modules is configured to receive an externally input 100G optical signal, convert it into an electrical signal, and then convert it into a new 100G optical signal for output. The main control module is configured to set relevant parameters of the 100G-QSFP28 optical modules, and monitor and report in real time the relevant data of each 100G-QSFP28 optical module. The multiplexing / demultiplexing module is configured to combine the optical signals output by multiple 100G-QSFP28 optical modules into one or more paths for long-distance transmission, or demultiplex the received optical signal and distribute it to each 100G-QSFP28 optical module for processing.
[0019] In this embodiment, by integrating two or more 100G-QSFP28 optical modules, the device can simultaneously process and transmit multiple 100G optical signals, greatly improving the overall transmission bandwidth and capacity. This is of great significance for application scenarios that require handling large-scale data traffic. The design of the multiplexer / demultiplexer module enables the device to flexibly combine or demultiplex multiple optical signals, which means that during transmission, the transmission path and quantity of optical signals can be dynamically adjusted according to actual needs, thus improving the flexibility and adaptability of the device. Each 100G-QSFP28 optical module has high-speed optoelectronic conversion capabilities, capable of quickly converting the received optical signal into an electrical signal for processing and then converting it back into an optical signal for output. This efficient conversion mechanism reduces signal processing latency and improves transmission efficiency. The main control module is responsible for setting the relevant parameters of the 100G-QSFP28 optical module and real-time monitoring of its working status and data. This intelligent management method enables the system to promptly detect and handle potential problems, ensuring that each optical module can operate in an optimal state. At the same time, the main control module can also report the monitored data to the upper-level management system, providing strong support for the operation and maintenance and optimization of the system. By integrating multiple optical modules and implementing parallel processing, the device can automatically adjust the transmission path when a single optical module fails, avoiding the impact of a single point of failure on the entire device. In addition, the real-time monitoring function of the main control module also helps to promptly detect and isolate the faulty module, thereby improving the overall reliability of the device. Since the device realizes centralized processing and transmission of optical signals, it reduces the dependence on physical lines and equipment, simplifies the wiring complexity and maintenance difficulty. At the same time, the intelligent management method also reduces the need for manual intervention and lowers the operation and maintenance costs.
[0020] Preferably, the number of the 100G-QSFP28 optical modules is six.
[0021] In this embodiment, six 100G-QSFP28 optical modules work in parallel, and the total transmission bandwidth can reach 600 Gbps. This is a huge advantage for application scenarios that require extremely high bandwidth support, such as hyperscale data centers, high-speed scientific research networks, etc. This high-bandwidth capability ensures that data can be transmitted quickly and without blockage in the network. The redundant design of the six optical modules enables the system to have a stronger response ability in the face of single or multiple optical module failures. Even if some optical modules fail, the remaining optical modules can still continue to work, ensuring the continuity and stability of data transmission. This fault-tolerant mechanism improves the reliability and availability of the device. By precisely configuring the six optical modules, the system can flexibly adjust resource allocation according to actual business needs, which helps to avoid resource waste and optimize cost-effectiveness. At the same time, the unified management and scheduling of the six optical modules also simplify the operation and maintenance work and reduce the long-term operation cost. The six optical modules can support different types of data transmission requirements, including but not limited to Ethernet, SONET / SDH, Fibre Channel, etc. This diversity enables the device to better adapt to the needs of different application scenarios and enhances the flexibility and efficiency of data transmission.
[0022] Preferably, the main control module monitors the relevant data of each 100G-QSFP28 optical module in real time through the I2C interface.
[0023] In this embodiment, the I2C interface is a widely used serial communication protocol that supports two-way communication between multiple devices and has simple hardware connections and flexible configuration capabilities. Through the I2C interface, the main control module can efficiently communicate with each 100G-QSFP28 optical module to obtain its working status, performance parameters, and possible fault information in real time. Traditional optical module monitoring usually requires manual intervention to obtain data by reading the indicator lights on the optical module or connecting dedicated test equipment. With the real-time monitoring function of the I2C interface, device administrators can perform monitoring and management remotely, greatly simplifying the complexity and workload of operation and maintenance work. The digital communication characteristics of the I2C interface enable the main control module to easily integrate with remote management systems or automated operation and maintenance tools, which means that system administrators can remotely access and control the optical modules through the network to achieve functions such as automated configuration, monitoring, and fault handling, further improving the operation and maintenance efficiency and response speed.
[0024] Preferably, the 100G-QSFP28 optical module includes a QSFP28 chip and its peripheral circuits.
[0025] In this embodiment, as Figure 2As shown in the figure, "GND" (ground) and "VCC" or "VCC_QSFP28_1", etc. are mentioned multiple times. GND represents the ground wire, which is the path for current to return, while VCC represents the positive power supply voltage used to power the components in the circuit.
[0026] There are multiple groups of signal lines marked as "Q_TXx_N1" and "Q_TXx_P1" in the figure, which are used for differential signal transmission. Differential signal transmission transmits information through two signal lines with opposite phases to improve signal integrity and anti-interference ability. Similarly, "Q_RXx_N1" and "Q_RXx_P1" represent the differential signals at the receiving end; "TXxN" and "TXxP" also represent the transmitting ends of the differential pair, while "RXxN" and "RXxP" represent the receiving ends. Here, "x" refers to the channel number. For example, TX1N and TX1P represent the differential transmission lines of the first channel.
[0027] The "QSFP28_LPMT", "QSFP28_RSTL1" mentioned in the figure are related to functions such as rate selection or power consumption selection. Signals such as "MODSELL" and "LPMODE" are used for the selection of the main control module and the low-power mode.
[0028] The two signals "SCL" and "SDA" also appear in the figure. They are the bus clock line and data line of I2C respectively, which are used for communication between the main control module and the peripheral devices; "INTL" represents the interrupt signal, which is used to notify the processor when a specific event occurs.
[0029] Preferably, the main control module includes an MCU chip and its peripheral circuit.
[0030] In this embodiment, as Figure 3 shown, MCU chips such as QSFP28_LPM_MCU2 and CSFP28LPMMCU1 are used to be responsible for processing data and controlling other components. The MCU chip communicates with external components through pins, receives input signals and outputs control signals.
[0031] Signal interfaces such as PA13UTMS / SWDIO, PA12 / CAN_TX, PA11 / CAN_RX, etc. These pins provide interfaces for communication with other devices or systems. For example, the CAN bus interface is used for real-time data exchange between devices, and USART is used for serial communication.
[0032] Special function pins such as PC13 / TAMPER / RTC (Real Time Clock / anti-tampering / reset control), PA0WKUP (wake-up pin), etc. These pins have special functions, such as system reset, time synchronization or wake-up in the low-power mode, etc.
[0033] Crystal oscillators such as OSC_IN and OSC_OUT are used to provide a stable clock signal for the MCU, ensuring that the MCU can execute operations according to the predetermined timing sequence.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
