| 摘 要： | 对啁啾光纤光栅在超长距离多波长传输系统中应用时所存在的问题进行了研究，主要分析了多波长级联的啁啾光纤光栅之间的串扰，并提出了利用相干长度法来抑制不同信道间啁啾光纤光栅串扰的方法.在此基础之上实现了基于光纤光栅色散补偿的8×10Gbit/s,1500km G.652光纤上的传输系统.

| Abstract: | An application of chirped fiber grating in an ultra long-hual DWDM system is presented in the paper. The interaction between the chirped fiber gratings at different wavelengths are analyzed for the first time. A method of prolonging the distance between gratings to surpass the coherent length of the light source is proposed to suppress the interaction between the gratings. By using chirped fiber gratings, we realized a transmission system of 8×10Gbit/s signal on G.652 fiber over 1500km. |
