光网络中色散补偿和光分插复用的同时实现

Simultaneous Realization of Chromatic Dispersion Compensation and Optical Add-drop Multiplexing in Optical Network

提出了一种在光网络中同时进行色散补偿和光分插复用的方法,并进行了特性分析。设计中,采用啁啾光纤光栅补偿光网络中不同波长信道的色散积累,同时,让不满足布拉格反射条件的光波透过,形成下路信号。与下路信号具有相同中心波长的光信号也可以作为上路信号,进入光网络进行传输。

A novel method realizing chromatic dispersion compensation and optical add-drop multiplexing simultaneously in optical network has been proposed and characterized. In the design, a chirped fiber Bragg grating is used to compensate the chromatic dispersion in different channels. And at the same time, it can allow the optical signal that dissatisfies the Bragg reflective condition to transmit, forming the drop signal. And alike that, the optical signal having the same wavelength with the drop signal can be used as the add signal and transmits in the optical network.
