摘　　要：　以建立基于ATM的无源光网络(ATM PON)宽带接入系统基本模型为基础,阐述传输帧格式,结合媒体接入控制(MAC)协议对传输帧结构内信元构成机理进行深入分析;对APON系统在物理层传输上的测距技术、突发模式同步技术、突发信号的收发技术进行了探讨,同时提出设计的基本框架。Based on the basic model of APON broad band access systems, the format of transmitting frame is discussed. The mechanism of the composition of cells in the transmitting frame structure is analyzed in terms of the MAC protocol. Several technologies such as ranging of APON systems in the tier of physical transmission, burst mode synchronization, transmitting and receiving of burst signals are discussed. The basic framework for the design is proposed.
