Video over BPON with integrated VDSL

The next generation of access networks will be required to support a wide r ange of services, both narrowband and broadband, including broadcast video. While IP is the dominant technology at the network layer, ATM is the prefe rred technology for the data link layer because of its ability to support q uality of service. At the physical layer, a hybrid architecture such as a B PON optical feeder and VDSL for the final drop offers a cost-effective solu tion for providing the necessary bandwidth. The Full Service Access Network group and the Full Service VDSL Committee are actively working to generate contributions to the International Standards bodies in support of BPON and VDSL respectively. This paper summarises the work of these groups and disc usses solutions for the next generation of access networks with particular emphasis on support for video services.
