Can we use SFP transceiver with a "X710 Dual Port 10Gb Direct Attach SFP+ Converged NetworkAdapter"?

[AnoopS]

Hi,

I have this following NIC - "Intel X710 Dual Port 10Gb Direct Attach, SFP+ Converged Network Adapter".

I need to use this NIC on my serer, which would then be plugged into a switch which has a 1G connection though. From what I understand I can't use a SFP+ transceiver for my X710 since it is 10G, and have a peer switc connection which is 1G, since this is not compatible and the speed won't be autonegotiated down to 1G from 10G on my X710.

Instead will my X710 work if I instead plug a SFP(1G I assume) transceiver with my X710, instead of a SFP+ transceiver, so that way my X710 will be 1G and the peer switch it is plugged in would also be 1G?

Thank you for posting in Intel Ethernet Communities. 

We don't recommend using 3rd party SFP+ cables and modules on our ethernet cards. For more details, please open the link below to know more about compatibility and to get the list of compatible SFP+ cables and modules.

Thanks for the response. I did check the link you gave, but it doesn't mention any 1G SFP(not SFP+) modules.

Does this NIC support 1G SFP modules and are any available from Intel?

Hello AnoopS,

On the link that I provided, kindly expand the first topic it says there:

• Intel® Ethernet SFP+ SR Optics and Intel® Ethernet SFP+ LR Optics are the only 10-Gbps optical modules supported. You can purchase these modules separately.

Kindly expand the different topics to know more information and compatible modules and cables.
