摘要
简要介绍了10G GPON的系统结构和工作原理,比较分析了10G GPON技术的优势,进而研究了现有GPON向10G GPON系统升级的过程以及上下行对称10G GPON的关键技术,最后提出了一种新的10GGPON的实现方案,它兼容了现有的GPON,具有10Gb/s的上下行速率。它为将来10G GPON接入网系统的发展提供了参考。
The system structure and working principle of 10G GPON is briefly introduced.Comparatively analyzed technical advantages of 10G GPON,and intensively investigated the system updating process of GPON to 10G GPON as well as the critical technology of symmetrical 10G GPON. At last a innovative scheme of 10G GPON was proposed.Thise schemes,which is compatible with the existing GPON,and with 10Gbps upstream and downstream. It provide a good referrence for future 10G GPON access network system.
