It's PON, which means you are sharing the fiber.
https://en.wikipedia.org/wiki/Passive_optical_network
https://en.wikipedia.org/wiki/10G-PON

The 10G PON article talks about a 128-way split, which means worst case 
625Mbit/sec per home.

So while it's obviously better than 25Mbps, don't get excited about the 
headline 80Gbps.

I couldn't find out what the uplink speeds are. They will be less, as 
sharing the fiber in this direction is significantly more complicated.
