FTTH网络结构分析

Analysis of FTTH network architecture

文章描述了光纤到户(FTTH)在通信网中的位置及作用,FTTH系统的网络结构及功能要求。在FTTH的网络结构方面,通过对各种方案进行比较,建议在不同的应用环境中采取不同的网络方案。这些方案包括光纤到大楼(FTTB)的光网络,基于点到点的纤分方式,基于点到点结构的有源光网络,基于IEEE的以太网无源光网络(EPON)系统和基于ITU-T的吉比特无源光网络(GPON)的系统。

This paper described the position and role of FTTH system in the communication network, its network architecture and required functions. For the FTTH network architecture, we compared many different schemes and proposed that differend network schemes must be adopted according to the concrete application environments. These schemes include FTTB optical network, point-to-point fiber-division scheme, point-to-poin active optical network, IEEE-based EPON system and IUT-T-based GPON system.
