基于时分复用的Cameralink高清视频光纤传输技术

Fiber optical transmission of Cameralink high-speed video based on TDM

针对Cameralink高清视频传输距离受到限制的问题,提出一种光纤远距离传输方案。采用FPGA为核心处理芯片,利用硬件描述语言实现多通道信号的时分复用和解复用,最终完成了非压缩视频信息的光纤传输。经某型高速视频处理系统的应用证明,该系统稳定、可靠,满足工业需求。

To overcome the limitation of transmission distance of CameralinkTM, this paper presents a solution of fiber optical long-distance communication. FPGA was used as the main processing chip. The time division multiplex （TDM） and demultiplex of multi-channel signals was realized by hardware describe language, and a non-compressed digital video optical fiber transmission system was built up. This system was proved to be stable and reliable by the application of a high-speed video processing equipment.
