摘　　要：ONT是实现APON接入系统中光纤入户的重要设备,其TC子层及与ATM层接口芯片的开发是ONT产品的重要组成部分。本文结合ONT的具体研制工作,提出了传输汇聚子层（TC）及其同ATM层UTOPIA接口的模块化设计方案及FPGA芯片的选择。ONT is one of the important apparatus in APON access system, which can make the fiber come to home. Designing its TC sublayer and interface with ATM layer is a crucial component in developing ONI. According to the research on ONT in this paper, the designing method is put forward with which all the functional blocks of the ATM TC sublayer and its UTOPIA interface can be realized. Besides, how to choose FPGA chip to realize the design is discussed.

关 键 词：ATM 传输汇聚子层 UTOPIA接口 FPGA ONT 光网络终端
