摘要
ＡＰＯＮ系统是一种优良的高速、宽带接入解决方案，世界上许多科研机构和通信公司不惜投入巨资进行大规模的研究和开发。本文简述了 ＡＰＯＮ接入系统的网络分层结构、光网络终端的各功能模块。通过对系统的整体分析，确定了光网络终端设计中的核心工作是物理层实现，进而本文提出了物理层芯片的实现途径并给出了整个光网络终端的实现框图。
As a high-speed and broadband finely access platform, APON is studied arid developed in secret process way by lots of science institutions and telecommunications carriers with vast suni of funds. The layered structure of APON access network and ONT functional blocks is described in this paper. After analyzing the whole system, we make certain that the main working of ONT is designing PHY. Further the realize way for PHY is put forwarded in this paper. Finally, the whole blueprint of ONT is given.
