Hi there! My ISP is turning into a multi-gig provider, so I’m starting to plan to migrate my home network to 10G (would like 25G, but I think the price is too spicy still). First, I’ll build a dedicated PC to run OPNSense, because my current box is limited to 2.5g nics. My ISP handoff is 10G copper, and nobody was able to run a XGS-PON SFP successfully with this particular ISP, so I will need to stick to their ONT and use cupper between the ONT and OPNsense for now.
My question is. I read that SFP+ 10G Base-T runs super hot, but since Im building it specifically for this, I was wondering, if it is better/cooler to have a 10G NIC (for the uplink) and a 10G SFP+ NIC (for the downlink)? or just buy a dual SFP+ NIC, and use a Base-T SFP for WAN and Base-LX for LAN?
ps. I’m just starting with the planning, so L2 is not yet into the picture :)
ps2. the distance between the ONT and OPNsense PC is less than 2 meters.
ps3. i know a lot of ppl think a 10G circuit it’s useless, so it’s out of discussion if it’s worth or not to migrate to a 10G WAN/LAN setup.
Thanks!
If it runs hot but still works, it works.
Unless you get a sketchy NIC, you should be fine with copper for 2m.
For the LAN side, it depends.
If you’re gonna run a new cable through your walls either way, might as well run fiber than copper.
