[Abstract]:With the development of optoelectronic technology and digital communication technology, optical fiber transmission has been widely used in optoelectronic detection engineering practice. In this paper, the optical fiber transmission technology and the related technology in the field of high speed data transmission are analyzed, and the present situation and development trend of the related technology at home and abroad are investigated. On this basis, the design and implementation of the high speed and large capacity optical fiber image data interface based on FPGA platform and Camera Link standard is completed according to the customized requirements of the actual project. The specific research work is as follows: through the analysis of system requirements and technical indicators, the overall framework of the system is constructed. The hardware part of the transmission system is designed and implemented, and each module is designed concretely. The factors affecting the integrity of high speed link signal, such as jitter, reflection, attenuation and crosstalk, are analyzed theoretically, and the optimal design method of PCB is given. The key signal is simulated and designed by Hyperlynx software, which ensures the signal quality and reduces the bit error rate (BER). The software part of FPGA is designed by VHDL language. The main software modules, such as interface buffering, clock management, parallel port conversion, image transmission control, image data alignment, RocketIO GTP configuration and main controller, are introduced in detail. The functional simulation of the software module is carried out with VHDL. Finally, a test experiment platform is built for the design and implementation of the software and hardware system. The rate, bit error rate and real-time performance of the optical fiber transmission interface are tested, and the image of the high-speed camera is transmitted and restored by using the transmission system, and the quality of the transmitted image is evaluated. The test results show that the optical fiber data interface meets the technical specifications and meets the design requirements.
