Analysis of FTTH network architecture

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.
