The Spectrum-X Photonics Ethernet and Quantum-X Photonics InfiniBand platforms deliver speeds of 1.6 Tb/s per port (twice the maximum of current top-tier copper Ethernet solutions)

Uh, sorry but which part is copper? You mean the connection to the transceiver module?

Also, I'm suspicious Nvidia is summing together bandwidth in each direction, like they usually do.

For comparison, here's an overview of Broadcom's tech:
