Fabric.AI and Kopin White Paper Models Up to 60% GPU utilization Gain with MicroLED optical interconnect

A joint white paper from Fabric.AI and Kopin models that replacing copper interconnects with MicroLED optical channels could boost GPU utilization from 35-45% to 50-60%, cutting training time by up to 38%. The Neural I/o architecture targets 1 picojoule/bit and extends high-bandwidth reach to tens of meters. Public demo planned for January 2027, production silicon in 2028.
