All-optical switching data center network supporting 100Gbps upgrade and mixed-line-rate interoperability

Over an 8-rack, 32-server WDM-based all-optical switching data center network, we show the network upgrade using single-wavelength or multi-wavelength 100 Gbps signals, and further show the mixed-line-rate interoperability between 100 Gbps and 10 Gbps signals.
