摘要： 光纤通信系统在工业现场应用日益广泛，针对现有光纤通信系统通用性、灵活性不足等问题，设计了一套通用性强、结构轻便的光纤通信系统。采用FPGA作为主控制器，通过USB3.0总线从上位机接收指令及数据，然后在光纤通信链路上完成数据发送与接收，并控制串化-解串器芯片和光电转换模块完成信号形式的转换与传递。实验结果表明，系统在1.6 Gb/s的有效速率下长时间通信无误码出现，能够正确可靠地执行数据传输任务。

Design of fiber-optic communication system based on FPGA

Abstract： Fiber-optic communication system is widely used in industrial field. To solve the problems that the existing system lacks generality and flexibility, a set of fiber-optic communication system with strong versatility and light structure is designed in this paper. FPGA is used as the main controller, it can receive the instruction and data from the host computer through the USB3.0 bus, complete data transmission and reception on the fiber-optic communication link, and control the SerDes and the fiber-optic transceiver to complete the conversion and transmission of signals. The experimental results show that the system can communicate correctly and reliably under the rate of 1.6 Gb/s.
