WUS Printed Circuit says 1.6T switch products enter mass shipment

The significance here is less about any single speed grade and more about the sequencing: mass shipment at 1.6T, small-batch supply at 224Gbps, and pre-research already pointing at 3.2T and 448Gbps. That ladder suggests the supplier is being pulled forward by super-node architectures that bundle compute, switching and interconnect rather than by isolated component demand. The open question is whether small-batch and pre-research stages convert into volume on the same cadence, or stall while the next node is defined.
