Michael Posted January 26, 2017 Posted January 26, 2017 Hi all, Is there such thing as an HP DAC (Direct Attach Cable) for SFP (1Gb), not SFP+ (10Gb) which I'm already aware of! If yes, what's the product number? Many thanks!
NB9457 Posted January 26, 2017 Posted January 26, 2017 IIRC, 10Gb SFP modules are backwards compatible, so should work fine. Just double check, but I'm fairly confident.
localzuk Posted January 26, 2017 Posted January 26, 2017 I've never seen one - but there are SFP copper modules - J8177C, for example.
NB9457 Posted January 26, 2017 Posted January 26, 2017 I'm guessing it's something like this you're after?

I didn't think they were, I thought they varied in size ever so slightly but I might be wrong on these. I also thought they used different protocols, hence no direct compatibility.

Cisco do a 1Gb DAC, but I can't find a HP one; although as I say HP do a 10Gb DAC.

If it's cheap enough, just have a stab at the Cisco one, we use Cisco 1Gb modules in our 10Gb dell switches and have used mixed brands in the past too, I'm not sure but the whole SFP branding thing seems to be a bit of a scam, prices are all over the place for some modules!
whitte Posted May 12, 2017 Posted May 12, 2017 SFP+ cable cannot plug into SFP port. You can go straight to fs.com to buy cheap 1G copper or fiber SFP. Custom & OEM HPE Gigabit Ethernet SFP Transceivers | FS.COM
Mark-wilde Posted May 12, 2017 Posted May 12, 2017 I rarely see the 1G DAC cables. It is advisable for you to have the SFP 1000BASE-T modules and cat5e cables or go for the SFP Fiber modules and fiber patch cables. Both of the solutions are cheap nowadays.
IanT Posted May 13, 2017 Posted May 13, 2017 HP do the 10gig version, part number: J9283A But if you only need 1gig just get a copper SFP
OPTCORE Posted May 23, 2017 Posted May 23, 2017 Agree, 1000base-T copper SFP will works, you could connect by CAT5 cable, max distance is 100 meter 1
