We consider optical switching architectures that allow for scaling to a large number of ports. We show that the complexity of the node control critically depends on the node architecture and impacts the end-to-end latency of the system. We introduce, node architectures with highly distributed control that allow for systems that introduce very low end-to-end latency.
We review our work on optical switching architectures that allow for scaling to a large number (thousands) of ports. We explain that the complexity of the node control critically depends on the node architecture and, hence, critically impacts the end-to-end latency of the system. We introduce node architectures with highly distributed control that allow for systems with very low end-to-end latency...
We demonstrate for the first time 40 Gb/s operation of a modular large port count optical packet switch with highly distributed control. The switch shows 25ns latency and record low energy consumption of 76.5 pj/bit.
