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 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.
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.
FS have inexpensive switching and SFPs. Even if you get another brand switch I still recommend FS SFPs which can be ordered for compatibility with various vendor equipment.
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 use a mikrotik RB5009 for my 2.5gb routing. It technically can hit 10gbps via routing.

I don’t have an exact answer for you but went through this a few years ago with the help of a thread on DSLReports
There’s a lot of info there and can be a bit tough to follow but it should get you what you need.
