Abstract :
A gigabit-to-the-home (GTTH) system is proposed as a future ultra-broadband access network and its feasibility is investigated. GTTH is based on PON architecture and offers a very large downstream capacity of 2.5 Gb/s. Thus, various broadband communication services and digital video broadcasting services with a great many channels can be simultaneously provided. GTTH also has high flexibility due to its multiple-interface architecture, which enables multiple systems to be integrated regardless of their signal formats, protocols and transfer modes. In order to reduce the cost of GTTH-ONU, a high-speed CMOS DMUX IC, a waveguide PIN-PD and a one-chip receiver are developed. The service integration capability of GTTH is shown through a GTTH demonstration system
