摘要: Deployment of optical fiber in the subscriber loop may eventually lead to a full-scale deployment broadband network. A network architecture that can be introduced inexpensively meet near-term demand and upgraded smoothly support future needs is desired. The feasibility applying multiaccess architectures loops studied, five for passive this need are presented. All these use double-star topology dense wavelength division multiplexing downstream direction; however, various topologies techniques used upstream direction. Limitations on node size, frame synchronization, cost, privacy security, standards discussed. >
