We propose a novel network architecture that exploits coarse granular routing while add/drop operations are done at wavelength granularity. For the proposal, we introduce a node architecture and a network design algorithm. Numerical results demonstrate that the proposed architecture’s performance approaches that of single-layer optical path networks while substantially reducing hardware scale.
