Technical Field

[0001] The utility model relates to the technical field of Vmux optical multiplexing, and particularly relates to a Vmux optical multiplexing device supporting multiple application scenarios. Background Art

[0002] In the context of the rapid development of optical communication technology, as a key component in modern communication networks, the performance and flexibility of optical multiplexing devices are crucial for ensuring the efficient and stable transmission of the network. Traditional optical multiplexing devices are often limited to specific application scenarios and are difficult to adapt to the increasingly complex and changeable network environment, especially in large data centers, long-distance backbone networks, and future 5G / 6G wireless communication networks that require high reliability, flexible switching, and fine optical power management.

[0003] Specifically, with the explosive growth of data transmission volume, a single optical fiber link has been difficult to meet the high-bandwidth and low-latency transmission requirements. Optical multiplexing technologies such as dense wavelength division multiplexing (DWDM) have been widely used to increase the transmission capacity of optical fibers. However, traditional optical multiplexing devices often lack sufficient flexibility and adaptive capabilities when facing challenges such as input optical power fluctuations, transmission link failures, and large differences in optical signal quality requirements for different services.

[0004] In addition, the requirements for optical multiplexing devices in different application scenarios are also different. For example, inside a data center, rapid and interruption-free optical path switching may be required to support high-dynamic traffic; while in long-distance backbone networks, the stability and long-distance transmission ability of optical signals are more emphasized; for the optical multiplexing devices in the wireless communication fronthaul network, they also need to support high-density wavelength division multiplexing and adapt to the requirements of rapid base station deployment and change. Summary of the Utility Model

[0005] In view of this, the utility model provides a Vmux optical multiplexing device supporting multiple application scenarios, which can solve the defect in the prior art that it cannot meet the requirements of different application scenarios for optical multiplexing devices.

[0006] The technical solution of the utility model is realized as follows:

[0007] A Vmux optical multiplexing device supporting multiple application scenarios, comprising a photoelectric detection module, a variable optical attenuation module, an optical switch module, a main control module and a demultiplexing and multiplexing module. The photoelectric detection module is used to detect the input optical power and output optical power, and convert the detected optical power value into an electrical signal and send it to the main control module. The main control module is used to judge the input optical power and output optical power of the device according to the electrical signal provided by the photoelectric detection module, and realize the switching of the main path transmission link or the backup path transmission link by controlling the optical switch module. The variable optical attenuation module is used to adjust the attenuation amount of the optical signal according to the instruction of the main control module, and cooperate with the demultiplexing and multiplexing module to perform multiplexing on the input optical signal and then demultiplex it into optical signals of multiple channels for output. The demultiplexing and multiplexing module is used to perform multiplexing on the input optical signal and then demultiplex it into optical signals of multiple channels for output.

[0008] As a further optional solution of the Vmux optical multiplexing device supporting multiple application scenarios, the number of the photoelectric detection modules is twelve.

[0009] As a further optional solution of the Vmux optical multiplexing device supporting multiple application scenarios, the photoelectric detection module includes a photodetector and its peripheral circuit.

[0012] As a further optional solution of the Vmux optical multiplexing device supporting multiple application scenarios, the main control module includes an MCU chip and its peripheral circuit.

[0013] The beneficial effects of the present utility model are as follows: The photoelectric detection module can monitor the input and output optical powers in real time and convert these optical power values into electrical signals and send them to the main control module. This enables the main control module to quickly and accurately obtain the status information of the current optical path. Based on the data provided by the photoelectric detection module, the main control module can intelligently determine whether the input optical power and output optical power of the device are within the normal range. Once an abnormality is detected (such as too low or too high optical power), it can immediately achieve a rapid switch between the main path transmission link and the backup path transmission link by controlling the optical switch module, thereby ensuring the stability and reliability of optical signal transmission. The variable optical attenuation module can dynamically adjust the attenuation amount of the optical signal according to the instructions of the main control module. This function is crucial in the process of optical signal transmission because it can ensure that the optical signal has an appropriate power level when reaching the receiving end, avoiding receiver saturation caused by too strong optical power or signal distortion caused by too weak optical power. The flexible attenuation adjustment ability also enables the device to adapt to different lengths of transmission links and different optical signal quality requirements, improving the applicability and flexibility of the device. The multiplexing and demultiplexing module can perform efficient multiplexing processing on the input optical signals, that is, combine optical signals of multiple wavelengths into one optical fiber for transmission, thereby saving optical fiber resources and reducing transmission costs. At the same time, the multiplexing and demultiplexing module can also demultiplex the combined optical signal into optical signals of multiple channels for output, meeting the requirements of different receiving ends for the wavelengths of optical signals. This multiplexing and demultiplexing ability makes the device have broad application prospects in wavelength division multiplexing systems. By integrating multiple functional modules such as photoelectric detection, variable optical attenuation, optical switch, main control, and multiplexing and demultiplexing, the device can achieve comprehensive monitoring and flexible control of the optical signal transmission process, thereby greatly improving the reliability and stability of the system. Especially in the face of complex and changeable network environments and sudden optical path failures, the device can quickly respond and take corresponding countermeasures to ensure the continuity and stability of optical signal transmission.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1 to 5 , a Vmux optical multiplexing device supporting multiple application scenarios, including a photoelectric detection module, a variable optical attenuation module, an optical switch module, a main control module, and a demultiplexing and multiplexing module. The photoelectric detection module is used to detect the input optical power and output optical power, and convert the detected optical power value into an electrical signal and send it to the main control module. The main control module is used to judge the input optical power and output optical power of the device according to the electrical signal provided by the photoelectric detection module, and realize the switching of the main path transmission link or the backup path transmission link by controlling the optical switch module. The variable optical attenuation module is used to adjust the attenuation amount of the optical signal according to the instruction of the main control module, and cooperate with the demultiplexing and multiplexing module to perform multiplexing processing on the input optical signal and then demultiplex it into optical signals of multiple channels for output. The demultiplexing and multiplexing module is used to perform multiplexing and then demultiplexing on the input optical signal into optical signals of multiple channels for output.

[0022] In this embodiment, the optoelectronic detection module can monitor the input and output optical powers in real time and convert these optical power values into electrical signals and send them to the main control module. This enables the main control module to quickly and accurately obtain the status information of the current optical path. Based on the data provided by the optoelectronic detection module, the main control module can intelligently determine whether the input optical power and output optical power of the device are within the normal range. Once an abnormality is detected (such as too low or too high optical power), it can immediately realize the rapid switching between the main path transmission link and the backup path transmission link by controlling the optical switch module, thereby ensuring the stability and reliability of the optical signal transmission. The variable optical attenuation module can dynamically adjust the attenuation amount of the optical signal according to the instructions of the main control module. This function is crucial in the optical signal transmission process because it can ensure that the optical signal has an appropriate power level when reaching the receiving end, avoiding saturation of the receiving end caused by too strong optical power or signal distortion caused by too weak optical power. The flexible attenuation adjustment ability also enables the device to adapt to different lengths of transmission links and different optical signal quality requirements, improving the applicability and flexibility of the device. The multiplexing and demultiplexing module can perform efficient multiplexing processing on the input optical signals, that is, combine optical signals of multiple wavelengths into a single optical fiber for transmission, thereby saving optical fiber resources and reducing transmission costs. At the same time, the multiplexing and demultiplexing module can also demultiplex the combined optical signal into optical signals of multiple channels for output, meeting the requirements of different receiving ends for the wavelengths of optical signals.

Especially in the face of complex and changeable network environments and sudden optical path failures, the device can quickly respond and take corresponding countermeasures to ensure the continuity and stability of the optical signal transmission.

[0023] Preferably, the number of the optoelectronic detection modules is twelve.

[0024] In this embodiment, more optoelectronic detection modules mean that the monitoring points for optical signals are denser, thus enabling more detailed and comprehensive optical power monitoring data to be provided. This helps to more accurately capture the tiny changes in optical signals during transmission, promptly detect potential problems. Twelve optoelectronic detection modules are distributed at multiple key positions in the input end, output end, and transmission link, resulting in a higher monitoring coverage of the entire optical path and reducing monitoring blind spots. When an optical path failure occurs, multiple optoelectronic detection modules can simultaneously provide optical power data at different positions, facilitating the rapid location of the specific position where the failure occurs. The main control module can more accurately determine the type of failure, providing strong support for subsequent troubleshooting and repair work. The configuration of the twelve optoelectronic detection modules can be adjusted and optimized according to specific application scenarios and requirements. For example, the number of optoelectronic detection modules can be increased at certain key nodes or positions prone to failure to improve the monitoring intensity and accuracy of this area. This flexibility enables the device to better adapt to optical transmission networks of different scales and structures, meeting diverse application requirements. The redundant design of multiple optoelectronic detection modules improves the fault tolerance of the system. Even if some detection modules fail or malfunction, other detection modules can still continue to work, providing effective monitoring data to ensure the normal operation of the entire system. At the same time, more comprehensive monitoring data also helps to detect potential problems or hidden dangers in advance, avoiding the serious impact of single-point failures on the entire system, thereby improving the reliability and stability of the system.
