The word is these new modules will use less power and be less scortchy than existing 10GbE choices. ref: https://www.cnx-software.com/2025/05/22/realtek-rtl8127-rtl8...

What kind of cables do you need to connect to your 10Gb switch/router? Do you need glassfiber?
I run 10g-base-t over cat5e. I think the standard says cat6, but the nics can't read the markings on the cable :p
If you want to add 10G to existing systems, cards with the old Niantic 82599EN chipset are cheap and widely available (now branded Intel). They use the IXGBE driver in Linux, and work out of the box on Windows as well. SFP 10G fiber transceivers are much cheaper than 10G copper: I saved money by using OM3 instead of cat6, but YMMV. https://www.amazon.com/dp/B01LZRSQM9 https://www.amazon.com/dp/B01DCZCA3O An old PC I…
For me, using sfp+ means paying for a transceiver or a DAC, vs using my existing stash of rj45 terminated cables. Some of the ebay cards come with fiber transceivers at no extra cost though. So from that perspective, total cost is about the same either way. And I can use the cabling that's already in my walls.
However, switch pricing is still way in favor of sfp+, and my two 'core' switches have only 2x sfp+ and 2x 10g-base-T, so I use the ports I have.

That link is a 404, but I found what I believe you intended to share (subtracted the extra wwwww's in "low"): https://www.cnx-software.com/2025/05/22/realtek-rtl8127-rtl8...

I get my 10g stuff off ebay. x520 dual sfp+ cards are about $10, x540-T2 dual 10g-base-T cards are about $20.

I have an x540-T2 in my firewall and it's performant if hot. I keep a fan on it.

This is really helpful information, thank you! $30/card out the door isn't bad, although I wonder what the power draw is like. I've noticed my SFP+ 10gbit cards and transceivers get quite warm (different models from what you linked).

Buyers of x540 chipsets will want to know they are 1Gb/10Gb. They don't do 2.5Gb or 5Gb. I have an x540-T2 in my firewall and it's performant if hot. I keep a fan on it.
Oh my god can you please just use normal SFP+ already.
