摘　　要：为了降低多路数据光纤通信的系统成本,提高性能,提出了一种基于XC2VP30的多路数字视频光端机的设计。光端机利用视频压缩和XC2VP30内嵌的MGT模块,实现多路数字视频的实时传输。设计主要包括数字信号的复用/解复用,数字视频压缩/解压缩,高速并/串转换等部分,应用FPGA编程,8B/10B编码以及视频压缩等技术实现了高速视频信息的无误传输。利用Virtex II Pro开发板进行硬件调试,实验证明设计结构简单,成本低,性能稳定,抗干扰能力强,可用于管道、公路、楼宇等处进行监控,在工业中具有很大的应用价值。In order to reduce the cost and improve the performance of the multiplexed optical fiber communication system, this paper presented an optical terminal for digital video signals based on XC2VP30. Using video compression and MGT, the optical terminal can transfer multiplex video signals over an optical fiber. The design mainly included the digital-multiplexing/de-multiplexing, the video compression/decompression and the transmission between parallel signals and serial signals. The design used the FPGA programming, 8B/10B channel coding and video compression technology to realize the correct transmission of the high-speed video signals. The debugging of the hardware used the Virtex Ⅱ Pro. It is proved by experiments that the design has characteristics of simple structure, low cost, stable performance, and strong anti-interference. It can be used widely in the fields of intelligent transportation, monitoring and controlling of logistics, security monitoring, etc.
