Ah, of course. I was misled by wikipedia[1], but it should've been obvious that the same connection could be used for both inifinband and ethernet. So, indeed, there are copper interconnects:

Actually seems the price is finally coming down a bit (compared to what I remember these used to cost, years ago -- but maybe I've just upped my budget ;-).

"The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. It interfaces networking hardware to a fiber optic cable."
But it also interfaces hardware to copper cables, as I gather.
