摘要
通过对DWDM系统在中继段引入备用路由,减少人工调度时限,实现系统及时恢复,减轻传输网维护压力及避免影响客户感知,介绍了OLP光保护的技术原理及工作方式,通过对每个系统段色散补偿说明,光功率补偿说明及方案分析等,对OLP光保护的具体应用中各部分细节展开详细论证。
By introducing backup route into the relay section of DWDM system,the manual scheduling time limit is reduced,the system can be recovered in time,the maintenance pressure of transmission network and the impact on customer perception can be avoided.The technical principles and working methods of OLP optical protection are introduced.Through the description of dispersion compensation,optical power compensation and scheme analysis of each system segment,the details of each part in the specific application of OLP optical protection are demonstrated in detail.
