A novel architecture for dense wavelength-division multiplexing/subcarrier multiplexing networks

摘要

We propose and demonstrate a new survivable dense wavelength-division multiplexing/subcarrier multiplexing (DWDM/SCM) network based on the star-bus-ring architecture (SBRA). This architecture ensures an OBI-flee optical network, and can serve tremendous subscribers. In addition, remote nodes and bidirectional wavelength add/drop multiplexers (B-WADMs) are designed by using simple optical switches to reconfigure the network under link failure. We further set up an experimental network to demonstrate the feasibility of the proposed architecture.
