I didn’t know this was a thing. I interpreted the question as fiber.... Using SFP and a fiber “cable” is an excellent thing to run up a tower.
Have never seen these DACs. From: Josh Reynolds Sent: Sunday, January 15, 2017 7:17 PM To: [email protected] Subject: Re: [AFMUG] Direct attach sfp cables?

They are obviously going to be thicker than individual strands of fiber. We regularly terminate 2 racks of dual homed servers in one cabinet using nothing but DACs.

I thought it would be a great idea to put a couple hundred DAC'd ports in a rack. Terrible idea. Never again.

Seems like it would pretty much always be better to just use fiber... Super cost effective way to connect a rack full of servers to a TOR 10G switch. ~Seth
