This might be the appropriate support answer - Netgear does (like many other vendors) only support their own modules. However, they don't reject modules not carrying the appropriate vendor ID and name in this switch class.
The point is - as explained before - is that (lack of any link speed negotiation in the SFF standards) you can't operate SFP+ modules in SFP ports, you can't link a 1000BASE-SX-/LX with a 10GBASE-SX/-LX module, and you can't use a DAC to connect an SFP with an SFP+ port, too.
The problem with your initial post is that you have not provided any information on how you tried to connect. In the SFP/SFP+ world, things are much more complex than with copper Ethernet.
It's key to explain on how you tried to link the Intel adapters (with SFP+ 10G/1G typically) to the GS750E (SFP, 1G only). As neither fiber links nor DAC connections know anything like automatic link rate negotiation, the link speed must be equal on both sides.
Examples:
You can't use a DAC cable to connect an SFP+ with an SFP port (no DAC for SFP to SFP btw,, too - only SFP+ to SFP+).
For a fiber link connecting an SFP+ adapter to an SFP device like the GS750E, you must use 1G fiber modules on both ends. SFP+ slots can work with 10G and 1G SFP modules.
Another restriction can exist on the Intel SFP+ adapters: Some are designated -DA ... these can only be used with [passive] DAC, the slots can't acommodate active modules like fiber or active DAC [longer DAC cables].

The first sentence in my initial post is :"I am trying to connect with SFP to two different Intel Network cards, X722 and X710 and I do not get a Link LED. The INTEL cards have SFP+ ports."
The title/header has the part numbers. I am not sure what else I would have added.
