Highly spectrally efficient metro networks that adopt fiber-level granular routing on overlaid line-/ring-shaped virtual topologies
Paper in proceedings, 2020

We propose a cost-effective metro network architecture with fiber-granular routing and path-granular add/drop operations together with its ILP-based design algorithm. The proposal alleviates the impact of filtering impairment while using already deployed OXC/ROADM nodes. Numerical simulations on several real-world metro topologies verify that it increases the spectral efficiency compared to the ideal method for DWDM networks.
