[WA2-4] Switching Granularity and Intra-node Interconnection Optimization for Large Scale Optical Nodes

Invited

〇Hiroshi Hasegawa, Ken-ichi Sato (Nagoya Univ., Japan)

Keywords:Design of node architectures including optical core/metro protection and restoration

Dense inter-connections embedded in optical cross-connect nodes and how they limit node scalability are reviewed. By reducing inter-connections at express and add/drop parts, a cost-effective node architecture named subsystem modular OXC node and a compact bank configuration of transponders/receivers are derived. Their validities are numerically verified through simulations.
