Design and Implementation of a Multi-Channel Fiber Optic Communication System Based on Domestic SOPC

To ensure stable, efficient communication and reliable data transmission among various modules of the high-voltage programmable power supply, a multi-channel fiber optic communication system based on domestic SOPC was designed and implemented using a domestic FPGA as the carrier. An ARM Cortex-M1 soft-core processor was embedded in the Gowin FPGA to control peripherals and interact with the host computer. Multiple-channel data processing and arbitration modules were designed using Verilog HDL. These modules, along with Serdes interface and SFP optical modules, were utilized to construct the communication system. Test results demonstrate that the system meets the requirements of isolated communication for high-voltage programmable power supplies, ensuring stable and reliable communication for extended periods in environments with multiple channels and mixed priority levels.
