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.

    Have a look at the Mikrotik switches (the ones that can run routerOS like the CSS610-8P-2S+IN). I don’t know much about fiber and up to now I didn’t even know that the 10Gbps SFP+ transceivers couldn’t work at 2.5Gbps, but have a look at the Optcore Sober transceivers. I’ve just found them doing a rapid searche, I don’t know them.

    But if you could go the OPNsense route that @ostsjoe suggested, that would be better!

    I have no way to test this with the equipment I have, but what about opnsense on an x86-64 box and throw an sfp+ pcie card in there. You could then in theory turn off auto negotiation and set it to 2.5g. Has anyone out there tried this?

    I’ve been running opnsense with my CenturyLink 1g setup, though I’m still using their ont to convert to copper, and been very happy with it.
