[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Referring to Figures 1 to 6 , an optical signal amplification device for an optical transmission device includes a Raman module, a main control module, and a power supply module. The Raman module is used to amplify the optical signal by using the Raman scattering effect. The input / output serial port of the main control module is connected to the input / output serial port of the Raman module for receiving, processing, and outputting signals. The power supply module is used to provide working voltages for the Raman module and the main control module.

[0020] In this embodiment, by adopting the Raman module and using the Raman scattering effect to amplify the optical signal, this technical solution can effectively enhance the intensity of the optical signal, extend the transmission distance of the optical signal in the optical fiber, and solve the defects of uneven gain, noise accumulation, and poor gain effect in certain specific wavelength ranges existing in the prior art. In addition, the input / output serial port of the main control module is connected to that of the Raman module, realizing the reception, processing, and output of signals. This design enables the entire optical signal amplification device to have a high level of intelligence. The main control module can monitor the working state of the Raman module in real time, quickly process the received optical signal, and adjust the parameters of the Raman module as needed to achieve the best amplification effect. At the same time, the main control module can also communicate with external devices to achieve remote monitoring and control, improving the flexibility and reliability of the system. The power supply module provides stable working voltages for the Raman module and the main control module, which is the key to ensuring the normal operation of the entire optical signal amplification device. A stable power supply can prevent equipment failures caused by voltage fluctuations, improving the reliability and service life of the equipment.

[0021] Preferably, the Raman module includes three Raman units with different parameter configurations, namely a first Raman unit, a second Raman unit, and a third Raman unit. The three Raman units with different parameter configurations are used to meet the optical signal amplification requirements in different application scenarios.

[0022] Preferably, the first Raman unit includes a first data receiving amplifier and its peripheral circuit, the second Raman unit includes a second data receiving amplifier and its peripheral circuit, and the third Raman unit includes a third data receiving amplifier and its peripheral circuit.

[0023] In this embodiment, by providing three Raman units with different parameter configurations, this technical solution can more flexibly meet the optical signal amplification requirements in various application scenarios. Different application scenarios may require different performance parameters such as amplification gain, bandwidth, noise figure, etc. The different configurations of the three Raman units can optimize these parameters respectively to meet specific application requirements. Each Raman unit is optimized for its specific parameter configuration, which means that in their respective application scenarios, they can provide more efficient and stable optical signal amplification effects. Compared with a Raman module with a single configuration, this multi-configuration design can more precisely match the actual application requirements, thereby improving the amplification efficiency and performance of the overall device. During the device design stage, engineers can select appropriate Raman units for configuration according to specific application scenarios, which simplifies the device design process. At the same time, during the debugging stage, since the performance parameters of each Raman unit have been optimized, the stable operation of the device can be achieved faster, reducing the debugging difficulty and time cost. By providing dedicated Raman unit configurations for each application scenario, this technical solution helps to reduce device failures and performance degradation caused by parameter mismatches. Each Raman unit has been strictly tested and verified to ensure its stable and reliable operation in actual applications.

[0024] Preferably, the main control module includes an MCU chip and its peripheral circuits.

[0025] In this embodiment, as Figure 5 shown, the picture shows multiple pin numbers, such as specific MCU pin numbers like PE4, PA13 / JTMS / SWDIO, etc. These pins are used to connect external devices or internal functional modules, such as communication interfaces, power supplies, grounds, timers, ADC / DAC, etc. C16 and C17 mentioned in the figure, marked as 20pF, are capacitor components used for circuit functions such as filtering, decoupling, or energy storage. Pins such as PA13 / JTMS / SWD IO and PA12 / CAN_TX not only have general GPIO (General Purpose Input / Output) functions but also undertake specific functions, such as JTAG debugging interface (JTMS / SWDIO), CAN bus communication (CAN_TX / CAN_RX), etc. Pins such as PC14 / OSC32_IN and PC15 / OSC32_OUT indicate that the circuit board uses an external clock source (such as a 32kHz crystal oscillator), which is crucial for the accurate timing and stable operation of the MCU. At the same time, the figure also includes a reset circuit for resetting the MCU when the device malfunctions or needs to be restarted.

[0026] Preferably, the power supply module includes a voltage conversion chip and its peripheral circuits.

[0027] In this embodiment, as Figure 6As shown, the circuit includes multiple parts related to voltage conversion, such as "DRA_RX_5V" and "DRA_TX_3V3". These markings indicate specific voltage conversion modules or circuits used to convert the power supply voltage (such as +5.0V) to 3.3V or other required voltages. There are also markings such as "DRA_TX_3V3", "DRA_TX_5V", and "DRA_RX_5V" in the circuit, which represent signal transmission paths of different voltage levels and are used for communication with external devices or modules. There are multiple capacitors in the circuit (such as C32, C33, C34, C35, etc.). These capacitors are mainly used for filtering and decoupling. Filtering capacitors (such as C32 and C33 with a value of 22uF) are usually used to smooth the power supply voltage and reduce the impact of power supply fluctuations on the circuit. Decoupling capacitors (such as capacitors with a value of 0.1uF) are used to reduce high-frequency noise in the circuit and improve signal quality. The circuit diagram includes multiple input and output pins, which are connected to the I / O ports of the main control module or other digital signal processors for signal input and output. The pins marked with "DRA_TX_" and "DRA_RX_" represent the data receiving (RX) and transmitting (TX) functions and are used for serial communication with external devices or modules. The resistor network (such as R8 to R121, etc.) plays multiple roles in the circuit, including current limiting, voltage division, impedance matching, etc.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
