Abstract
Starting from the research of RFoG optical network technology and combining with the development of PON network, this paper puts forward a kind of integrated optical network structure, which can multiply the access bandwidth; furthermore, it analyzes the key technologies such as optical devices and integrated terminal equipment, and provides a technical scheme for upgrading the network.
Introduction
According to the “broadband China” strategy released by the China state council, by 2020, the broadband network will fully cover in urban and rural areas, the household penetration rate of fixed broadband will reach 70%, and some households in developed cities can reach 1 gigabit per second (Gbps).At present, the telecommunication network adopts EPON or GPON technology to connect to the optical fiber for household entry, and the total bandwidth of the access network is 1.25 Gbps or 2.5 Gbps. The radio and television adopts DOCSIS 3.0 technology, and combines RFoG fiber into the household, with a total bandwidth of 860 Mbps. Whether EPON or GPON or RFoG, the optical network is accessed by light: 1:32 or 1:64, that is, 32 users or 64 users share the total bandwidth.Therefore, there is still a gap between the goal of 1Gbps access for family users.
