It’s a PCIe tunnelling protocol, sort of. The other simpler one is Oculink.

Most of the time you could do the same thing with USB <4 without slowdown.

Does Oculink have any special sauce to it? I was under the impression it presented itself as regular old PCI-e and it is really "just" a cabling solution.

I’m not entirely sure. It definitely don’t have its own protocol like Thunderbolt and can’t possibly be secured.

Good to know! Thanks.
