Next-gen AI networks may hinge on the telephone switchboard's return

Nvidia is pouring billions into optical circuit switching (OCS) to enable next-gen AI clusters packing hundreds to thousands of GPUs per rack, investing $6B across Coherent, Lumentum, and Marvell, plus $125M into iPronics' second-gen OCS tech.
