摘要
光纤色度色散是限制光信号传输速率和传输距离的主要因素之一,也是目前高速光通信系统中迫切需要解决的问题.介绍了单模光纤的色散组成,详细推导了描述色度色散的脉冲展宽的计算公式,分析了调相位法测量色度色散的过程,解析了进行色度色散补偿的必要性,给出了啁啾光纤光栅进行色度色散补偿的原理,并对单模光纤的发展动态做了阐述.
Fiber chromatic dispersion is not only a major factor restricting the transmission velocity and distance but also a problem pressed for urgent solation in high-speed light communication systems at present. In this paper the components of single-mode fiber dispersion are introduced and the formula of calculating pulse expansion for chroma dispersion is deduced. Moreover, the progress of measuring chromatic dispersion by modulating phase is analyzed and the necessity for compensating chromatic dispersion is parsed while the theory of the chirped fiber bragg grating compensation dispersion is given and the developmental trend of single-model fiber is expounded .
