光纤传输特性对视频传输系统非线性失真的影响

THE INFLUENCE OF OPTICAL FIBER TRANSMISSION PROPERTY ON NONLINEAR DISTORTION OF VIDEO TRANSMISSION SYSTEMS

详细地分析了采用ＰＦＭ调制方式的光纤视频传输系统的非线性失真，比较了光纤传输特性对等宽ＰＦＭ和ＳＷＦＭ两种ＰＦＭ系统的非线性失真影响，结果表明光纤带宽减小对ＳＷＦＭ系统非线性失真影响比等宽ＰＦＭ大。

The nonlinear distortion of optical fiber video transmission systems for PFM modula-tion ways is analyzed in detail.The influences of optical fiber transmission property on the nonlin-ear distortion of equal width PFM and of SWFM are compared.It is shown that the influence ofoptical fiber band width decreasing on the SWFM system is greater than on the equal width PFMsystem.
