Google Fiber came to town last year and I've had their 1Gig (up and down) service for about 9-10 months. It's a dramatic improvement over Comcast and the bill never changes, unlike Comcast.

They've recently turned on 2, 5 and 8 Gigabit connections here. My newer switch and Wifi gear (Unifi) supports 2.5G wired and 6E and 7 Wifi support greater than 1Gigabit as well (even if a single device won't saturate it).

Currently, I have a Unifi Dream Machine (not the Pro or SE). It looks like a little white R2D2. It's been pretty good, but starting to show limitations. If you turn on the firewall and intrusion detection/prevention, its throughput drops considerably below 1 Gbps.

The Google Fiber modem has a fiber ONT plugged into the SFP jack. I see reports on Reddit and elsewhere of people plugging the ONT directly into the SFP+ ports on their router and the ONT will train at 2.5/5/10 Gbps, thereby bypassing the modem completely. Some say they've done this on the UDM Pro or SE, but it doesn't seem to universally be the case, or the setup is a bit janky.

Anyone doing anything like this, either with Unifi routers or another router setup? Maybe a dual SFP+ Mikrotik.

For those who wonder why I want more speed, there are two reasons. One is that I look at radiology images at home and more speed makes this more efficient. The second reason is because I can.

I spent two days trying this with Verizon FIOS. Didn't work. Come to find out, the ONT is necessary on all Verizon drops. Copper then, to the UDMPro-SE. I can connect at 2.5Gb to the AP, again copper. Doesn't really bother me, but fiber all the way would have been nice.

I have no experience with Google fiber. Is it simplex or duplex?

I have UniFi UDMPros in four locations. I like the ease of configuring without a command line being necessary. The SE is nice.

I do have a 10Gb fiber trunk from one floor to another at one site, so I do know that the fiber SFP transceivers do work well with the SE.

If you sign up for service beyond 1 gbps they should provide you with an ONT that has a >1gbps port to connect to the rest of your network.  Don't forget to get your computer connected with a 2.5 or 10 gbps wired interface as well.

Google Fiber is 1/1 (down/up), 2/1, 5/5, and 8/8. I'm not sure why the 2Gig plan is only 1Gig down. It looks like a simplex fiber cable coming in to the house.

I have 10 Gb fiber from my workstation to my Unifi switch downstairs and it's connected to my NAS. So that part is great. I have the 10GTek transceivers off Amazon, which are much cheaper and work great with the Intel card in the computer and the Mellanox in the NAS.

I have read reports of people pulling the Google Fiber ONT out of the modem and plugging it directly into the SFP+ WAN port on a UDM SE with some success. That's what I'm hoping to figure out before I go out and buy a UDM Pro SE.

I'm reading that once you sign up for 5 or 8 Gig, the GF replaces the ONT and modem with another one.

My workstation is 10Gb fiber. I've changed out a few of my NICs to 2.5Gb, since they're Cat5e and it's not yet worth the hassle to pull new, faster cable.

If the provided router has a 10gbe or sfp+ lan port I would just connect your switch to that, turn off the router's bullt in wifi if any, and call it a day.

They have an updated UDM pro Max  that's made for faster, larger setups

Just build a cheap pfsense/opnsense box with a dual port/quad port SFP+ NICS. connect SPF+ to Brocade or other used enterprise gear SFP+ switches. 10G Fiber is cheap.

If Google delivers their ONT device as a standard SFP+ transceiver (yes there are XGPON SFP+ transceivers out there) then you theoretically just need a hardware device with SFP+ that will recognize the transceiver. The only gotcha is what AAA does Google use and does your device (whether that be Mikrotik, xSense, etc) support it.

Personally, I'm 100% Mikrotik for my home use but I also have several Mikrotik certifications and was at one point managing around 7,000 of the buggers. I'm also a big fan of VyOS over opnSense or pfSense but that's because I'm more into routing than I am advanced firewall (and I am not a fan of the UI used by xSense as I feel it's too slow and could do things more effectively in a CLI environment which is not where it should be for those two solutions.

The WAN port on the Google modem is an SFP+ cage. There's a 10 GBe LAN port to connect to the router (which I'm doing now). But I've read about people pulling the SFP+ out of the cage and plugging it directly into the SFP+ cage on some routers (like the Unifi Pro SE) and it will connect directly, completely bypassing the modem. This is what I'd like to do. I could run Cat 6 from the 10 GBe on modem to a 10GBe transceiver plugged into the SFP+cage on a router. But it's not guaranteed that the AAA (as below) will allow it.
The AAA is the gotcha. The /googlefiber and /unifi subreddits describe ways to do this. I do have a small Mikrotik switch with 4 SFP+ cages and a 1GBe management/POE port. I'm just a home user and hobbyist, but may try playing with this a bit more.
