There is gbic UTP 10Gbps?

Hi.

We have S8 and we want to know if is it possible gbic UTP 10Gbps.

Thks.

twinax cable would help you
something like that http://www.sfpopticaltransceivers.com/sale-2820312-multi-gigabit-10g-interconnect-sfp-twinax-copper-...

Hi Paulo, Copper/UTP SFP+ do exist, but not in any Extreme approved part. I believe the main problem with being able to use or support them is the inability to provide sufficient power over the interface to the SFP+ itself.

Actually we released in March such a transceiver:

10338 10Gb SFP+ 10GBASE-T 10Gb SFP+, 10GBASE-T RJ45, 30m with Cat6a

I believe it's only validated on EOS 8.62 or something like that, and not yet validated on EXOS. That would require a check.

Please note that such copper SFP+ are limited to 30m with Cat6a.

Drew's got it : power requirement for 10G-baseT exceeds the specifications of SFP+ interfaces. This is the reason why all manufacturers will address this need with Twinax/DAC copper cables or preconnectorized fibre cables. The drawback stays : maximum length is limited to several tens meters.

The other obvious option is to use 10G copper ports, but the cost of a linecard may be dissuasive

Extreme makes 1m, 3m, and 10m copper SFP+ cable assemblies. Part number for one meter is 10GB-C01-SFPP and their description is 10Gb, pluggable copper cable assembly with integrated SFP+ transceivers, 1 meter...
We have used these going from 670's to 460 and such and there are some nic cards that support them but problem is if you go outside Extreme gear your choices may be limited as you know some venders limit what can be plugged into their stuff... These are very cost effective for going from switch to switch.

on my experience, only HP (pre-commware) vendor were doing that.. Extreme, Cisco, DLink switches, and Intel NICs had no problems with that.

For example Cisco and Dell check these DAC (a.k.a Twinax) cables to be from Cisco resp. Dell, thus you cannot interconnect switches from those vendors with a DAC.

Other vendors, like Arista, do not check DACs, only SFP+ modules, to be branded correctly. This allows the use of any DAC cable (as long as it works, of course), even to connect to e.g. Cisco or Dell.

Extreme EXOS and EOS do not impose specific branding for either DAC of SFP+, 3rd party is fine if it works, but use of non-Extreme optics is not covered by Extreme support. Thus Extreme switches can even be connected to other vendor's switches using a DAC.

#10306 & 10307 should be workable.
