基于CWDM/DWDM技术的一体化光缆扩容系统的研制与应用

摘要

Aiming at the fiber optic cable channel with insufficient fiber core,the traditional transformation method is to reapply new op-tical cable,which has some problems,such as long construction cycle,difficulty and power grid coordination.Based on CWDM/DWDM technology,State Grid Huangshan Power Supply Company designs the optical cable technology routes and deployment model of system expansion and integration,creative system structure design is put forward.The compatibility of CWDM and DWDM technology is real-ized in same system equipment.The equipment has two types of transmission platform,which are combined organically.When the net-work transmission technology is upgraded to DWDM,the original CWDM transmission platform is not affected,it can continue to work properly.The seamless,smooth system upgrading is realized.The problems of traditional fiber expansion is solved to achieve two goals,i.e.rapid expansion of optical cable and CWDM/DWDM system smooth upgrade.%针对纤芯不足的光缆通道,传统改造方式为重新施放新的光缆,存在线路施工周期长、难度大、并且需电网配合停电等问题.基于CWDM/DWDM技术设计了一体化光缆扩容系统的技术线路及部署模式,提出具有创造性的系统结构设计,实现了同一台系统设备中同时兼容CWDM和DWDM技术,设备具有2种传输平台,并且有机结合,保证网络传输技术升级为DWDM时,原有的CWDM传输平台不受影响仍然继续正常工作,实现了系统无缝、平滑升级,彻底解决了传统光缆扩容存在的问题,实现了光缆的快速扩容和CWDM/DWDM系统平滑升级2个目标.
