Description

Technical Field

[0001] This application relates to the field of communication conversion technology, and in particular to a communication conversion device for convergence and splitting equipment. Background Technology

[0002] In the field of modern communication technology, the demand for high-speed data transmission is growing rapidly, and 400G and 100G high-speed communication technologies have become key drivers of industry development. With the explosive growth of data traffic, various communication devices are placing increasingly higher demands on high-speed and stable data aggregation and distribution capabilities. The development of 400G and 100G high-speed communication technologies enables communication networks to carry larger-scale data transmission, meeting the urgent needs of emerging fields such as cloud computing, big data, and artificial intelligence for data processing and transmission. This significantly improves the overall performance and efficiency of communication systems, providing solid technical support for the development of the information age.

[0003] In the past, the conventional approach to solving communication service conversion problems was to use equipment that only supported a single mode. One common method was to use equipment that only supported 1x400G mode, directly converting and transmitting 400G optical signals, suitable for scenarios with concentrated high bandwidth demands. Another method was to use equipment that only supported 4x100G mode, multiplexing 400G optical signals into four 100G optical signals for transmission, suitable for scenarios requiring distributed bandwidth. However, these devices typically focused on only one mode and could not be flexibly adjusted according to actual service needs, limiting their application scope. Moreover, in practical applications, a single device often only supports one 1x400G or 4x100G mode. When handling multi-line services, multiple devices were needed, increasing equipment costs and management complexity.

[0004] In other words, these existing devices can only support a single 1x400G or 4x100G mode, and cannot flexibly switch between the two modes or dynamically adjust according to different business scenarios and needs. Furthermore, each device typically only supports one 1x400G or 4x100G mode, which is insufficient to meet the processing needs of multi-line services, reducing the efficiency and flexibility of the equipment. Summary of the Invention

[0005] This application provides a communication conversion device for convergence and distribution equipment, which can flexibly switch between 1x400 and 4x100G modes to meet the processing needs of multi-line services.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: This application provides a communication conversion device for convergence and splitting equipment, including: a line-side 400G coherent optical module for photoelectrically converting an input 400G optical signal into an electrical signal; At least two customer-side optical modules and multiple ports electrically connected to the corresponding customer-side optical modules; The main control module is electrically connected to the 400G coherent optical module on the line side and is used to multiplex the electrical signal into four 100G electrical signals or convert it into one 400G electrical signal. The main control module is electrically connected to the corresponding customer-side optical module through the port, and is used to configure four 100G electrical signals or one 400G electrical signal to the corresponding customer-side optical module. The main control module can also collect the operating data of the line-side 400G coherent optical module and the customer-side optical module and upload them to the network management system.

[0007] By adopting the above technical solution, the 400G coherent optical module on the line side is electrically connected to the main control module, and the main control module is electrically connected to the corresponding customer-side optical modules through ports. This achieves the ability to flexibly switch between 1x400G and 4x100G modes, meeting the needs of multi-line service processing. This is because the 400G coherent optical module on the line side can convert 400G optical signals into electrical signals. The main control module can perform different processing on the electrical signals (multiplexing the electrical signals into four 100G electrical signals or converting them into one 400G electrical signal), and then transmit them to the corresponding customer-side optical modules through the ports to achieve mode switching. If there are multiple sets of the above modules, multi-line service processing can be realized.

[0008] Furthermore, the customer-side optical module includes a QSFP28 optical module and a 400G optical module.

[0009] Furthermore, the port includes four QSFP28 ports, which are electrically connected to the QSFP28 optical module respectively.

[0010] By adopting the above technical solution, this connection method enables signals to be accurately transmitted from the main control module to the corresponding QSFP28 optical module. For example, when the main control module multiplexes the electrical signal into four 100G electrical signals, they are transmitted to the QSFP28 optical module through the four QSFP28 ports respectively.

[0011] Furthermore, the port includes a QDD port, and the 400G optical module is a pluggable 400G QDD optical module that is plugged into the QDD port.

[0012] By adopting the above technical solution, this connection method enables accurate signal transmission from the main control module to the corresponding 400G optical module. When the main control module converts the electrical signal into a 400G electrical signal, it transmits it to the 400G QDD optical module through the QDD port. Furthermore, the 400G optical module is a pluggable 400G QDD optical module, which facilitates installation and replacement. For example, if the 400G optical module fails, it can be quickly removed and replaced with a new 400G optical module without affecting the normal operation of the entire device.

[0013] Furthermore, the 400G coherent optical module on the line side is also a pluggable structure.

[0014] By adopting the above technical solution, the 400G coherent optical module on the line side adopts a pluggable structure, which facilitates installation and replacement. For example, when the 400G coherent optical module fails, it can be quickly unplugged and replaced with a new 400G coherent optical module without affecting the normal operation of the entire device.

[0015] Furthermore, it includes at least two sets of independent service channels, each set of service channels including the line-side 400G coherent optical module, the main control module, and the customer-side optical module.

[0016] By adopting the above technical solution, multiple lines of services can be processed simultaneously, improving the processing capacity and efficiency of the device. For example, when multiple different services need to be processed, one set of service channels can be configured in 1x400 mode, and another set of service channels can be configured in 4x100G mode. Different service channels can work simultaneously without interfering with each other, realizing flexible switching between the 1x400 and 4x100G modes to meet the processing needs of multiple lines of services.

[0017] Furthermore, the main control module is configured to monitor the signal-to-noise ratio and signal eye diagram of the line-side 400G coherent optical module and the customer-side optical module in real time, and send the monitoring results to the network management system.

[0018] By adopting the above technical solution, the main control module constantly monitors the operating status of each optical module, and promptly notifies the network management system to handle any problems found.

[0019] Furthermore, the main control module has a built-in signal equalization circuit, which is configured to eliminate the distortion of the electrical signal during the multiplexing process and maintain signal integrity.

[0020] By adopting the above technical solutions, signal distortion is prevented during transmission, thus ensuring signal quality.

[0021] In summary, this application includes at least the following beneficial technical effects: The communication conversion device of this application converts 400G optical signals into electrical signals through a 400G coherent optical module on the line side. The main control module processes the electrical signals according to different operating modes and transmits them to the corresponding client-side optical modules through the ports, realizing flexible switching between 1x400G and 4x100G modes. Simultaneously, multiple independent service channels can meet the processing needs of multi-line services. The main control module collects and monitors the operating data of the optical modules, and the built-in signal equalization circuit ensures stable operation of the device and signal quality. Compared with existing devices that can only support a single mode, this device greatly improves efficiency and flexibility, reduces equipment costs and management difficulty, and provides a better solution for communication service conversion.

[0023] The following embodiments will help those skilled in the art to further understand the function of this application, but do not limit this application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this application. These all fall within the protection scope of this application.

[0024] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of this application with unnecessary detail.

[0025] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0026] Reference Figure 1This application provides a communication conversion device for aggregation and splitting equipment, comprising: a line-side 400G coherent optical module for photoelectrically converting an input 400G optical signal into an electrical signal; a client-side optical module and multiple ports electrically connected to the client-side optical module, the client-side optical module including a QSFP28 optical module and a 400G optical module; and a main control module electrically connected to the line-side 400G coherent optical module for multiplexing the electrical signal into four 100G electrical signals or converting it into one 400G electrical signal; the main control module communicates with the client-side optical module through the ports. The QSFP28 optical module and the customer-side 400G optical module are electrically connected to output corresponding signals. The main control module can collect the operating data of the customer-side optical module and upload it to the network management system. The main control module is configured to multiplex the electrical signals into four 100G electrical signals and distribute them to the QSFP28 optical module when the aggregation and splitting device is in its first operating mode; and to convert the electrical signals into a single 400G electrical signal and connect it to the 400G optical module when the aggregation and splitting device is in its second operating mode. This achieves flexible switching between 1x400G and 4x100G modes, meeting the needs of multi-line service processing. This is because the line-side 400G coherent optical module can convert 400G optical signals into electrical signals, and the main control module can perform different processing on the electrical signals (multiplexing the electrical signals into four 100G electrical signals or converting them into a single 400G electrical signal) before transmitting them to the corresponding customer-side optical module through the port, thus achieving mode switching. If there are multiple sets of these modules, multi-line service processing can be achieved.

[0027] Specifically, the main control module can use a Gearbox chip and an MCU. The Gearbox chip can arbitrarily combine electrical signals; the MCU is used to control and read data from various optical modules and chips. The MCU can upload data to the network management system of the host computer via Ethernet. When the network management system detects data anomalies, it can send data to the MCU via Ethernet communication. The MCU receives the data and controls each optical module and chip according to the data content.

[0028] Specifically, the ports include a QDD port and four QSFP28 ports. The 400G optical module is a pluggable 400G QDD optical module, which is plugged into the corresponding QDD port. The four QSFP28 ports are electrically connected to the QSFP28 optical modules respectively. This connection method allows signals to be accurately transmitted from the main control module to the corresponding 400G QDD optical module and QSFP28 optical module. For example, when the main control module multiplexes the electrical signal into four 100G electrical signals, it transmits them to the QSFP28 optical modules through the four QSFP28 ports respectively; when the main control module converts the electrical signal into one 400G electrical signal, it transmits it to the 400G QDD optical module through the QDD port. Furthermore, the 400G optical module is a pluggable 400G QDD optical module, which facilitates installation and replacement. For example, when the 400G optical module fails, it can be quickly removed and replaced with a new 400G optical module without affecting the normal operation of the entire device.

[0029] In some embodiments, the line-side 400G coherent optical module is also a pluggable structure. This structure facilitates installation and replacement. For example, when the 400G coherent optical module fails, it can be quickly unplugged and replaced with a new 400G coherent optical module without affecting the normal operation of the entire device.

[0030] In some embodiments, at least two independent service channels are included, each service channel comprising the line-side 400G coherent optical module, the main control module, and the client-side optical module. For example... Figure 1 The system includes two service channels, Channel 1 and Channel 2. This allows for the simultaneous processing of two services; for example, Channel 1 can be configured in 1x400G mode, and Channel 2 in 4x100G mode. In Channel 1, the line-side 400G coherent optical module photoelectrically converts the input 400G optical signal into an electrical signal, and the main control module multiplexes this electrical signal into four 100G electrical signals. In Channel 2, the line-side 400G coherent optical module photoelectrically converts the input 400G optical signal into an electrical signal, and the main control module converts this electrical signal into a single 400G electrical signal. When the aggregation and splitting equipment is in the first operating mode (4x100G mode), Channel 1 operates, and the main control module distributes the four multiplexed 100G electrical signals to the corresponding QSFP28 optical modules. When the aggregation and splitting equipment is in the second operating mode (1x400 mode), Channel 2 operates, and the main control module converts the signal into a single 400G electrical signal and connects it to the corresponding 400G optical module. Channel 1 and Channel 2 can also work simultaneously without interfering with each other, enabling flexible switching between 1x400 and 4x100G modes to meet the processing needs of multi-line services.

[0031] Specifically, the main control module is configured to monitor the signal-to-noise ratio and signal eye diagram of the 400G coherent optical module on the line side and the optical module on the customer side in real time, and send the monitoring results to the network management system. The main control module constantly monitors the operating status of each optical module, and promptly notifies the network management system to handle any problems detected.

[0032] Specifically, the main control module incorporates a signal equalization circuit configured to eliminate distortion of the electrical signal during multiplexing and maintain signal integrity. The equalization circuit can employ an adaptive equalizer. An adaptive equalizer automatically adjusts its parameters based on the characteristics of the input signal to compensate for signal distortion. For example, it can employ a transverse filter structure composed of multiple tap coefficients. These tap coefficients are continuously updated based on the statistical characteristics of the input signal using an adaptive algorithm (such as the Least Mean Square Error (LMS) algorithm). When the electrical signal is input to the adaptive equalizer, it adjusts the tap coefficients according to the signal distortion, effectively suppressing the distortion of the output signal and thus maintaining signal integrity. Alternative adaptive equalizers can be other equalizers based on different adaptive algorithms, as long as they can automatically adjust parameters according to the characteristics of the input signal to compensate for distortion.

[0033] The communication conversion device of this application converts 400G optical signals into electrical signals through a 400G coherent optical module on the line side. The main control module processes the electrical signals according to different operating modes and transmits them to the corresponding client-side optical modules through the ports, realizing flexible switching between 1x400G and 4x100G modes. Simultaneously, multiple independent service channels can meet the processing needs of multi-line services. The main control module collects and monitors the operating data of the optical modules, and the built-in signal equalization circuit ensures stable operation of the device and signal quality. Compared with existing devices that can only support a single mode, this device greatly improves efficiency and flexibility, reduces equipment costs and management difficulty, and provides a better solution for communication service conversion.

[0034] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
