You mean use (X)SFP(+), not “use fiber”. The SFP+ copper twinax cables I use in my lab at home have lower latency than the majority of MMF/SMF transceivers on the market.

Yes, thank you for the clarification/nomenclature. My SFP+ on MMF (multi-mode fiber) has significantly lower latency than the copper 10GbaseT I use. I haven't measured the direct-connect copper (coax? twinax?) SFP+ latency, though.

I would be curious if the SFP for 1G using fiber also has lower latency than copper 1000baseT.
