SHORT VERSION:
Has anybody tested compatibility between any of the 'cheap' 10GBASE-T SFP+ Transceivers like from fs.com or edgeoptic.com and the 10G copper ports on a Xeon-D Supermicro sys-5028d-tn4t? What is the outcome?
LONG VERSION:
Looking at the various threads, when choosing between copper or fiber for 10G+ speeds, the consensus seems to be: go for fiber.
The problem is: how do I connect my Xeon-D system (sys-5028d-tn4t) that came with 10G copper ports to a mostly fiber network? My other servers have SFP+ connections.
My constraints:

My constraints:
- low power use
- preferably less than 500EUR excl VAT
- LAGG/LACP. That is not going to cut it, as I would need 10G speeds point to point (it is used mainly for file copy between servers), and LACP will not help there.
- NIC bonding in linux. That would help prevent the above issue, but is messy to set up, would not be universally applicable, and would not allow me to go over 3 or 4 gbps with the built-in NICs. Prefer not to.
- A mixed copper/fiber switch. The only switch I have seen that is under my price limit and has both SFP+ and 10G Base-T, is the Ubiquity ES-16-XG. That switch still has huge problems keeping 10G speeds on the copper ports, so is out of the question for now. Netgear XS708T is over my self-imposed price limit.
- Add a SFP+ card in the server. Bad luck, the only PCIe slot in the server is already full with NVMe drives.
- Use a 10GBASE-T SFP+ Transceiver. 330 EUR at fs.com or 272 EUR at edgeoptic.com. It would be an expensive link, but less expensive than a new switch. Could be promising.
- Has anybody tested any of the 10GBASE-T SFP+ Transceivers with the 10G copper ports on the sys-5028d-tn4t? It seems those NICs are particularly difficult.
- Any other options? (please don't propose a change of motherboard or moving NVMe disks elsewhere, that is all going to be more expensive when you take everything into account.)
