It appears that I solved the problem myself. I purchased a set of:
10Gtek for Cisco SFP-10G-LR, 10Gb/s SFP+ Transceiver module 1310nm, 10km

And the LR version worked instantly. I honestly don't know what the difference is between an SR SFP+ module and an LR SFP+ module but for whatever reasons the LR module allowed these two switches to connect.

Here are links to the modules and cable used in case anyone else needs a solution to this:

Hi bluefoot

We need to troubleshoot this incompatibility.

Would you provide us with what is displayed in Port Configuration table for that given port in XS748T?
(Switching > Ports > Port Configuration)

Then provide us with the content from Port Statistics for that port (Monitoring > Ports > Port Statistics).

And finally Detailed Port Statistics for that port as well (Monitoring > Ports > Port Detailed Statistics).

If you prefer, we can also open a case at Technical Support and remotely log into your installation.

We are taking interop issues very seriously and we are going to procure this Ubiquiti switch as well. But let us know how best we can help you right now.

Regards,

    Hi bluefoot,
    
    I'm glad that you issue is now sorted out. The problem may be from the older SFP modules that you have, probably compatibility? I encourage you to mark your post above as "Accept as Solution". So others can be confident in benefiting from the solution. The Netgear community looks forward to hearing from you and being a helpful resource in the future!
