It is important to realize the efficient accommodation of access traffic for various services that will have a wide dynamic range of bandwidth. To achieve this, we are studying a new access network based on multi-stage semiconductor optical amplifiers (SOAs), which has a multi-access point that separately accommodates different services. This paper describes the configuration and advantage of this network and presents a traffic design obtained by simulations that examined the number of optical-electrical-optical (OEO) conversions at first-in first-out (FIFO) controlling packets with a view to reducing power consumption.
