混合网络下双模ONU切换设计

Dual-mode ONU Mode Switching in Hybrid Network

随着三网融合、"光进铜退"国家政策推行和用户固网带宽需求增长,以EPON、GPON为代表的无源接入技术成为应用热点。国内PON网络以EPON、GPON共存,本文对E/GPON双模ONU做了研究,提出双模ONU的设计方案,市场应用前景广泛。

According to national policies, tri-network integration and ＂fiber in and copper out＂ are pushing ahead. And the fixed network band- width demand is growing. Represented by EPON and GPON, passive access technology has become a focus. In domestic PON network, EPON and GPON coexist. This paper proposes a scheme of dual-mode ONU based on EPON/GPON.
