yes i also wondering,but i guess is for future la.
some say fibre is near zero latency, ethernet got latency. fibre also can carry many different wavelengths in one single strand, might be more beneficial for full duplex saturation
my router not also is already capable of utilizing 10gbps internet, just need to upgrade switch later for fibre run or 2.5 / 10gbps to the whole house
right now everything is 1gbps,
Ok, so this is all hypothetical, but let's presume that Fiber <-> Copper Ethernet takes ~1 ms due to going through a switch/ONT.
Within the LAN, the latency woun't be affected enough to make any difference, since the connections will probably end up on the same switch where no media conversion is needed (unless you happen to use UTP for one connection and SFP for another).
For Internet connections, I think the latency would be affected more by routing, firewall & CGNAT (since most of us are still dependent on private IPv4 from the ISP). The additional latency due to media conversion is probably negligible as well.
So to me, the only use case for FTTR is being able to use the same fiber for future bandwidth upgrade beyond 1 Gbps. If that is the case, the difference between regular SFP Ethernet and FTTR seems to boil down to how much $$$ difference there is between the two deployments.
Edit: To add to the point I made, currently with PoE over UTP, we can already go up to 10 Gbps with less deployment issues (no need to have a power socket in the room location). So the window of opportunity for FTTR does not seem to be very large, unless they're targeting 10 Gbps and beyond. As a new technology, it's also competing against Ethernet which has wiped off all other competing standards over the years.
