I have server racks with storage devices at both end of my home which is why I want my internal network speeds greater than the 2.5 gig I get from my ISP.
My setup includes a Netgate 6100 running PfSense which currently handles all routing/firewall functions.
I have two satellites, one wired (Cat6e) and one wireless backhaul.
I was thinking about replacing the Cat 6e wired backhaul line with OM3 fiber and was wondering if anyone has tried this.
So the Orbi is in AP mode. And the Netgate only has 2.5 gbps ethernet.
You say you "have been converting to fiber". What have you done so far?
I'm not seeing the need to run fiber to the second Orbi satelite, as there is no immediate performance gain in doing that. Getting suitable switches with SFP+ ports would be the place to start. The switches will be the backbone of your network, so you don't want to undersize them.

So with the RBR in AP mode... it is currently fed as a separate and distinct line (knowing it is limited to 2.5 gig) which is independent from the rest of the house backbone which is fiber.
I also know that the line running from the RBR to the RBS performing backhaul has to be on the same trunk else it won't synch.
I wanted to be able to have a small switch where the RBS is that has 10G or higher capability (because there are devices near that would benefit from that speed).
Bottom line, probably dont NEED, just curious if it would work as I get rid of the dreaded cat 6

Well the cat-6 cable can also carry 10 gbps, so I am puzzled on why you are determined to get rid of it. Isn't it possible to run fiber to that spot while leaving the cat-6 as it is?
If not, then you could run fiber to a small smart switch, and set up one VLAN to connect the RBR to the RBS, and a second VLAN to connect your other devices. But you could also connect a small smart switch to the back with cat-6, and use VLANs to accomplish the same thing.

I mean, it isn't a quest get rid of Cat 6 -- more like a goal. Primarily for four reasons: 1. Futureproofing, 2. Speed, 3. Size (I have a lot of cables coming into rack through a 3" PVC pipe -- every but saved makes running/replacing the others better. 4. The RJ-45 SFP+ connectors run hotter than lava, and I know they are the major source of heat in my IT closet.
I guess the real reason? Because I can :) The more I do, the more I learn. Guess that makes me a nerd!
