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1dB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
The effect of chirped fiber grating on the optical pulse signal is analyzed. The pulse broadening after the optical pulse is transmitted through a certain distance and compensated by the chirped fiber grating is calculated. At the same time, the chromatic dispersion of the chirped fiber grating group is analyzed. influences. In the condition that the dispersion power of the system is generally less than 1dB, the amplitude of the delay jitter in the chirped fiber grating group is given, and the relationship between the period and the system single-channel rate is related
