摘要

采用流水线逐级上传的方法解决了电缆外部需要大量缓存的问题,采用基于LVDS(Low Voltage Differential Signaling)和双绞线的传输方式,实现了100m长度下160Mb/s的稳定传输,克服了传统系统中用光纤传输时不易维护的不足。系统在满足高速率传输的同时,具有成本低、使用方便、安装容易、体积小等优点,使电缆传输成功应用于海上地震数据传输系统。
The system employed pipeline method uploading data board-by-board to eliminate the demand of buffer storage off-cable.Moreover,the transmission method based on LVDS and twisted-pair was used in the system,which overcame the shortcoming of traditional system which use fiber as the transmission medium and carried out stable transmission at 160 Mb/s in 100 meters distance.The system not only satisfied the requirement of high-speed transmission,but had a lot of strong points,such as low-cost,easy to use and install,and space-saving,all of which made cable transmission successfully apply to marine seismic data transmission system.
