En Route to Grouping-Constraint Free,Colorless Directionless ROADMs
Networks Optical Communications All-Optical Networks
2015/6/5
WSS-based ROADM architecture limits local transponder wavelengths to a grouping constraint.3D-switch-based architecture offers powerful solution without grouping constraint. This paper presents an upd...
Route and Wavelength/Waveband Assignment for Creation of Compact Hierarchical Optical Cross-Connect for Multi-Ring Connection
Route Wavelength/Waveband Assignment Compact Hierarchical Optical Cross-Connect Multi-Ring Connection
2015/7/15
We propose a route and wavelength/waveband assignment method for multi-ring networks linked by hierarchical optical cross-connects. Numerical experiments reveal that the switch scale is significantly ...
Impact of Wavelength Route Correlation on the Optimal Placement of Optical Monitors in Transparent Mesh Networks
Wavelength Route Correlation Optimal Placement Optical Monitors Transparent Mesh Networks
2015/7/31
Wavelength route correlation is considered for optimal monitor placement in transparent networks. The associated reduction in monitoring requirement is studied as a function of repair cost and traffic...
