Thank you for writing to Intel Customer Support. It is recommended to use validated SFP+ or fiber module for Intel XL 710-QDA2, please refer to page 6 of the product brief for the supported module:
Thanks for quick response.
I referred to the link you have supplied and on page 6, QSFP+ details are provided as below:
We are using SR4 Optic E40GQSFPSR SFP module, is it correct? I mean with this SFP one should be able to bring the ports UP?
Also, the page mentions about Intel Ethernet QSFP+ Twinaxial calbles:
Should we use one of these cables only? Please mentioned which one we should use.
The one we are currently using is MTP 24 fiber optical cable, is it because of this we are facing link down issue?

Hi Anand Prasad,
Thank you for the clarification. XLDACBL is not optical cable. Let me check and at the same time can you share what is the exact MTP 24 fiber cable ? I searched on the web and found below MTP 24 cable information
https://www.fibertronics-store.com/media/24%20Fiber%20MTP-MPO%20OM3.pdf (note this is third party website for your reference, Intel is not endorsing this website and has no control over the content), is this the cable you used? With both end having one connector each? or if there are other variants?
If there is a picture you can share that would be great in case. Thanks.
Yes, we are using the same MTP 24 optical cable that is mentioned in the link you have provided.
For this cable we have attached below mentioned Intel QSFP on both ends of the cable:
Class 1 21CFR1040.10
But, with this, we are are not able to bring the ports [connected back-to-back ] to UP status.
Please let us know if this cable is compatible with "Intel Ethernet Converged Network Adapter XL710-QDA2" board along with the above mentioned Intel QSFP. If not compatible, then please let us know which optical cable should be used.
Thank you for the clarification. We are checking on this thus want to make sure this is the cable you refer to, I will update you once there is any information.
Further checking, you need to use the compatible and validated cable mentioned on our website:
