2.5g capable SFP+ switch or media converters (lemmy.world)

Is anyone aware of any switches (or media converters) with SFP+ ports capable of negotiating 2.5Gbit speeds that don't cost an arm and a leg?

I have the Google Fiber 2 gig plan and I'd like to get rid of the fiber box since they've been extremely unreliable and our 4th one has just died. Unfortunately in order to get the full speeds I need something that can take a 2.5 gig SFP+ connection. 10 gig will not work, and 1 gig obviously only gets me half the speed.

I've found a few Unifi compatible switches, but they're between $600 and $900 which is just insane for all we need.

Media converter wise everything I've found is 2.5gig on the rj45 side and 10 gig only on the SFP.

Something has to exist out there right? It can't only be Google who are the freaks using 2.5 gig SFP modules.

You’d need a card capable of 2.5 gig and I haven’t been able to find one of those either.

My friend did find these which should work. I think I have a spare 2.5 gig nic somewhere that I could install into my server. I’ll have to do pcie pass through straight to pfsense since ESXi doesn’t support this el cheapo consumer grade nic. But it should work.

This guy managed to modify a Broadcom NIC to support 2.5G SFP: https://github.com/Berzerker/google-fiber-2gbps-bypass

I mean it isn't great to have to mod something, but at least it's something

Edit: or apparently you can just ask for a 10G transceiver now: https://www.reddit.com/r/googlefiber/comments/tdgag5/google_fiber_now_installing_fiber_jacks_w10gbe/

Also I thought I should mention I don't have Google Fiber so I can't say if any of this works.

Awesome, I did not know about the 10gig they install now. We have someone coming on Tuesday and I was wanting to convince them to replace both the SFP module and the fiber box. But if we could just replace the SFP and get something that actually works then that’s great.
