Hi @m006

 

10G BASE-R supports data stream between board interface(SFP cable).

 

10G BASE-KR supports data stream across a backplane

Hi @m006

 

You can select either of the QSFP interface, make sure GT selection and configuration matching with QSFP1/QSFP2 while configuring the IP

BASE-KR enables FEC and AN.  If you don't need these, then you can just use BASE-R.
