What more could anyone need than this to tell you that ACC's are a major, major part of A.I. and that we are working with Nvidia?

These are all Nvidia Linear Active Copper, made by Volex using Spectra7 chips.

"Transceivers and Cables"
"400Gb/s InfiniBand (NDR) connectivity provides the maximum flexibility
to build a topology of choice, using connectorized transceivers with passive
fiber cables, active copper cables (ACCs), and direct attached copper cables
(DACs). The usage of MPO fiber cables enables the building of complex
infrastructures and simpler installation, maintenance, and upgrades.

> Similarly, switch-side, twin-port, copper DACs and ACCs are also offered
in straight or 1:2 or 1:4 splitter cables with single-port OSFP or QSFP112
endpoints to adapters and DPUs.
> The air-cooled Quantum-2 switches only accept twin-port, finned-top, OSFP
devices. DGX-H100 InfiniBand four OSFP cages only accept twin-port, flat-
top, 800Gb/s transceivers and ACCs. HCAs and DPUs only use flat-top OSFP
or QSFP112 devices.

The large selection of device combinations creates the following array of
interconnect choices:
> Quantum-2 switches-to-HCAs and DPUs: switch-side, twin-port, 800Gb/s
DACs, ACCs, and transceivers connect to the following devices:
> Two 400Gb/s NDR
> Four 200Gb/s NDR200
> Single-port OSFP or QSFP112

> Flat-top, twin-port, 800Gb/s transceivers and ACC cables can connect
DGX-H100 Hopper GPU systems to Quantum-2 switches creating 400Gb/s
NDR GPU compute fabrics, with minimum cabling.
