My ISP called me a while back and told me that they're decommissioning all copper infra, so it'd be better if I switch to fiber. I said OK.

They brought in a Nokia GPON ONT, and a new Zyxel router. I protested against the router, and I was ready to bypass it with bridge mode (whiich it allows), but with a reliable, powerful, and flexible WiFi6 router with better coverage than my WiFi5 one won over me, and I left it in service.

The thing is a beast with 4 different SSIDs plus a guest network, full gigabit ports and reliable operation. Plus it terminates my POTS line, too. It can handle the full 1000/50 mbps network without even getting warm, either.

So all in all, it's not a bad device overall, and I'm a happy camper.

Your fiber is asymmetrical (not 1g/1g) - like low-latency cable?

Actually, the hardware symmetric capable, but they don't provide symmetric service (yet?).

I think the two reasons are market segmentation and preventing people from running services from their homes. 50mbps is enough uplink for what I do, and I don't care about providing services or self-hosting from home.

I have enough experience to run my services somewhere else on an isolated network and absorb the mayhem outside my home network.

GPON is the most commonly deployed FTTH technology and is not symmetric, though it should be much closer than a 20:1 down:up ratio, much closer to 2:1 IME.
