A Novel Modularized Twin-Ring Wavelength-Division Multiplexer Access Network with Fiber-Fault Protection and Wavelength Tetra-Reuse

摘要

A novel modularized twin-ring wavelength division multiplexer access network is proposed in this paper. By originally designing the switch module and the exchange module, the central office and the remote nodes are formed respectively. This gives the network both modularity and scalability. By using twin-ring topology, the architecture of network is constructed. It makes the network not only have high reliability, but also support wavelength tetra-reuse. By simulation, the mentioned functions are demonstrated. The simulating results show the network has good performance.
