Optical Loss Property of IP Network with Wavelength-Selectable ROADMs
Due to recent exponential increase of network traffic volume,classical Optical Add/Drop Multiplexers generally cannot satisfy the requirement of keeping the framework of large capacity Wavelength Division Multiplexing network rapid and smooth variation along with the changes of network structure.Proposes Reconfigurable Optical Add/Drop Multiplexers to be used for constructing a fiber ring network.Establishes a 4-node optical network,which uses ROADMs as its main components.By experiments,optical losses of different fiber links,which consists of the ring network,are measured.The result shows the loss variation against light wavelength,and confirms reliable data transferring through fiber link of the ring network.
