Abstract

This paper proposes a new optical access network system; the multi-bit rate passive double star (multi-bit rate-PDS) system. The multi-bit rate-PDS system passes multi-bit rate data streams between the optical service unit (OSU) and the optical network unit (ONU) using the time-unit packet (TP). This simplifies the provision of user flexibility and provides very economical network services to users. We describe the architecture and frame structure of the multi-bit rate-PDS system, and elaborate the advantage of its user accommodation. Furthermore, we show how to decide the multiplexed bit rates in the multi-bit rate-PDS system and how to realize the receiver circuit for multi-bit rate data packet streams.
