This paper proposes an asymmetric bandwidth access network based on super-dense wavelength-division multiplexing (SD-WDM) technologies; the network guarantees 100 Mbps upstream and 1 Gbps downstream bandwidth to each user and supports wide-area transmission. The network minimizes operation and administration costs by consolidating switching equipment, as well as minimizing wavelength monitoring/stabilization functions by employing two technologies; the optical multi-carrier supply module (OCSM) for creating downstream signals and the directly modulated spectrum slicing scheme for creating upstream signals. After describing the configuration and features of the presented network, we demonstrate a bandwidth guaranteed network for each of 64 users with 100 Mbps upstream and 1 Gbps downstream bandwidth. The network provides 10-km access lines with under 7-dB loss from users to the access node and a 120-km metro-loop transmission line with under 25-dB loss from the access node to the center node.
