摘要
光纤色散是限制光信号传输速率和传输距离的关键因素之一,是目前高速光通信系统中迫切需要解决的问题。本文介绍了色散补偿光纤、啁啾光栅、高阶模色散补偿器以及VIPA等四种色散补偿技术的原理、技术特点以及国内外研究情况,现在不同的色散补偿技术正逐步成熟并走向应用,基于系统的需要,色散补偿器件在向宽带、可调谐方向发展。
Fiber dispersion is one of the key factors that limit the transmission rate and transmission distance of optical signal.The principle,technical features and research sta-tus native and abroad of the four dispersion compensation technologies:DSF,chirp grat-ing,HOM mode dispersion compensator and VIPA are introduced in this paper.Now,different dispersion compensation tech nologies are becoming mature and being used in the application.Based on the system re quire-ments,dispersion compensation compo nents are developing towards broadband and tunable components.
