We propose a highly scalable and compact optical-node architecture that combines the subsystemmodular optical cross-connect (OXC) and transponderbank add/drop, where multiple M × M wavelength-selective switches are effectively introduced. Numerical experiments verify that the proposed architecture offers large-scale nodes with substantially relaxed hardware requirements while holding the fiber-utilization...
We propose a novel optical-switch configuration for intra-datacenter interconnection that consists of tunable lasers, non-cyclic AWGs, and combinations of small-size optical switches and couplers. We develop an 800×800 switch prototype and its good performance and scalability are verified by experiments.
