It has been some time since I was connecting 10 GbE NICs (quibble, B
Bytes, b bits :) ) back-to-back, but presumably, if you have
compatible optical transceivers (*) in each, it should "just work."
Compatible optical transceivers here would be ones claiming to support
the same specs - I may not be using the correct terms, but both being
short-range optics, or both being long-range optics etc etc.
Things might be a little more complicated if you wish to use DAC
(Direct Attach Copper) cable. Unlike fibre, a DAC has a transceiver
at either end. Transceivers have IDs, and some NICs/vendors are more
particular about those IDs being in the set of supported devices than
others. The transceivers at either end of a DAC cable will be from
the same vendor. I don't recall if either Mellanox or Intel 10GbE
NICs are picky about such things.
If you are using 10GbE NICs with RJ45/UTP transceivers/connections,
you would need to use I think Cat6e or better UTP cable. Best double
check that though, I've never used 10GbE over RJ45/UTP.

Similar rules would apply with 40 GbE. I do not know of an RJ45/UTP
option at 40 Gigabit/s speeds.
No need to believe in either side, or any side. There is no cause.
