摘要
分析了啁啾光纤光栅对光脉冲信号的作用,计算光脉冲经过一定距离传输并由啁啾光纤光栅进行色散补偿后的脉冲展宽情况,同时分析啁啾光纤光栅群时延抖动对系统色散代价的影响.在系统色散功率代价一般要小于1 dB的条件限制下给出啁啾光纤光栅群时延抖动的幅度、周期与系统单信道速率这三个参量之间存在相互关系.
Abstract
In this paper, the effects of chirped fiber grating on optical pulse was analyzed, calculating the broadening of optical pulses after propagating through a certain fiber span and then compressed by a chirped fiber grating, considering the influence those ripples on increasing dispersion power penalty. According to the requirement that dispersion power penalty should be less than 1dB, the relationship between maximum amplitude, period of GVD ripples and system bit rate was investigated.
