Abstract

Optical access, or Fiber-To-The-Home (FTTH), has long been considered a final solution to the problem of upgrading the current bottlenecked access to the one capable of delivering future broadband, integrated-services. The high cost of large-scale deployment of fiber and optical network systems in the field under traditional point-to-point architecture, however, is a major economic barrier to the optical access. Also, current static optical network architectures cannot meet dynamic user demands based on on-demand service/usage models very well.

In this talk, we first describe a new architectural trend in optical networks ranging from Wide Area Networks (WANs) to Metropolitan Area Networks (MANs) to Access, and investigate the issues these new optical network architectures try to address. Then we introduce a newly-proposed "Stanford University aCCESS" (SUCCESS in short, a joint work between STMicroelectronics and Photonics & Networking Research Lab at Stanford), a next-generation hybrid WDM/TDM optical access architecture. In designing the SUCCESS architecture we focus on providing practical migration paths from current-generation TDM-Passive Optical Networks (PONs) to future WDM-based optical access networks. The SUCCESS can provide backward compatibility to the users on existing TDM-PONs while simultaneously providing upgraded, high-bandwidth services to the users on new DWDM-PONs through advanced WDM techniques. The SUCCESS architecture is based on a collector ring and several distribution stars connecting the Central Office (CO) and users. Semi-passive configuration of the remote nodes together with this hybrid topology enables protection and restoration, making it possible to support both Business and Residential users on the same access infrastructure.

Bio

Kyeongsoo (Joseph) Kim is STMicroelectronics Researcher-in-Residence at Stanford Networking Research Center and currently working on Next-Generation Access Architectures with focus on Optical Access. Before joining ST, Joseph worked with the PON Systems R&D group of Lucent Technologies and developed the first commercial ATM-PON-based Fiber-To-The-Home/Business (FTTH/B) system, which won the 1999 Bell Labs President's Silver Award. Joseph was also engaged in development of multi-channel ATM switching systems as a Post-Doc researcher at Washington University in St. Louis, Missouri, where he taught several undergraduate and graduate courses as Instructor of Washington University and Adjunct professor of University Missouri, St. Louis.

Joseph received his PhD in Electronics Engineering from Seoul National University, Seoul, Korea, in 1995.
