| Broadband fiber access is becoming increasing important in USA as major service providers are gearing to bridge the gap between world leaders in access (South Korea and Japan) and USA. This tutorial will first review fiber access technologies currently being deployed: passive optical networks (PONs) including A/B PON, E-PON and G-PON; and hybrid networks having both fiber and DSL segments. The issues of bandwidth, QoS and security will be discussed. Next, the tutorial will review possible evolution scenarios from hybrid PON / DSL networks to PON / wireless, pure PON, and next-generation PON networks. In the latter group, we will cover more powerful 10Gb/s TDM PONs and evolution toward even more powerful WDM PONs. Special attention will be paid to graceful, economically feasible evolutions scenarios.
This tutorial will include results of some six years of research conducted by my group, Photonics and Networking Research Laboratory at Stanford University. The research was conducted with a generous support of various industrial companies (including both service providers and equipment manufacturers) and government agencies (such as N F).
Biography:
Prof. Leonid Kazovsky joined Stanford University in 1990. Prior to that, he was with Bellcore conducting research on WDM, coherent optical communications and other advanced networking technologies. At Stanford, Prof. Kazovsky has founded and is managing Phonics and Networking Research Laboratory (PNRL). His laboratory is conducting extensive experimental and theoretical research into advanced networks specializing, over the last six years, in broadband fiber access. PNRL is especially interested in issues of graceful evolution of PON beyond current technologies including transition to PON / wireless networks and TDM-to-WDM evolution. Prof. Kazovsky has authored or co-authored hundreds of tutorials, invited and contributed talks at major conferences including GLOBECOM, ICC, OFC, CLEO and many others. Prof. Kazovsky is an author or co-author of hundreds of journal papers, two books and several book chapters. |
