摘要
Camera Link接口技术以其固有的特点,正逐步成为宽带高速系统设计的首选接口标准。在军用光电通信领域的应用更是日益普及,正在发挥着不可替代的作用。Camera Link传输电缆带宽宽,传输的数据量大,频率高,常规工艺制作的电缆不能满足高速高分辨率视频信号传输的要求,容易引起闪屏、丢帧、纹波干扰。按照六类电缆的标准,检测常规工艺制作电缆的插入损耗、回波损耗、串扰、电阻、HDTDR和HDTDX信息。分析影响电缆传输高速信号的主要因素,总结出一套Camera Link高速信号传输电缆的组装工艺。通过检测工艺改进后电缆的各项参数,结果表明工艺改进后的Camera Link电缆提高了高速信号传输质量,有效避免了不合格电缆导致的图像干扰和丢帧,为Camera Link电缆及相关高速信号传输电缆的组装提供了有益参考。
With the inherent characteristics of the Camera Link interface technology,it was gradually becoming the preferred interface standard for broadband high-speed systems.The application in military optoelectronic information field was more and more popular and was playing an irreplaceable role.Camera Link cable had wide transmission band,large data volume and high frequency,and the cable made by conventional technology could not meet the requirements of high-speed and high resolution video signal transmission,which was easy to cause splash screen,frame loss,and interference fringe.According to the cable standards of sixth category,it was detected such as the information of insertion loss,return loss,crosstalk,resistance,HDTDR and HDTDX of the cable made by the conventional process.The main factors affecting cable transmission of high-speed were analyzed,and a set of assembly process of camera link high-speed signal transmission cable was summarized.By detecting the parameters of the improved cable,the results showed that the improved Camera link cable could improve the quality of high-speed signal transmission and effectively avoid the image interference and frame loss caused by unqualified cable,which provided a useful reference for the assembly of Camera Link cable and related high-speed signal transmission cable.
