In order to solve the problems of low speed and low reliability in the process of long-distance transmission between high-speed image information acquisition terminal and storage terminal,a high-speed data transmission system based on SRIO is proposed.The system includes 1553B command receiving interface,SRIO data receiving interface,LVDS data reading back interface and memory data exchanging interface.This data transmission system cooperates with the unit testing bench and memory,and unpacks the data reading back by LVDS receiving interface through the upper computer software to check whether the received SRIO data has error code and frame loss.The system adopts retransmission mechanism to ensure that the data can be read back with high speed and reliability.It is verified that the SRIO data in the system can be transmitted at 2.5 Gbps and error free in 10 meters of optical fiber.
