Next Generation Optical Access Networks [PDF]
2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006 The last mile continues to be a major bottleneck in the Internet. Its low bandwidth and flexibility prevents the deployment of new services and the development of new applications. In this paper we present a summary of current efforts in access networks research, focusing in particular on fiber optic solutions. We present the Stanford University aCCESS
