| Abstract: | A new node architecture for a wavelength division multiple (WDM) packet switched metropolitan area network based on subcarrier multiplexed addressing and wavelength conversion technology is proposed. The network operates on dual bus topology and the tunable transmitter and fixed receiver scheme to facilitate data multiaccess. Subcarrier multiplexed addressing and wavelength conversion based on cascaded semiconductor optical amplifier perform the functions of subcarrier signal with data multiplexing and transparent transmission of payload. |
