GPON is 2.4 Gbps downstream and 1.2 Gbps upstream. Residential users are download heavy and more than 1:2. However there is a big difference between average, peak and micro burst. The conclusion is not simple.
We typically have 60+ users on each port. We sell 1000/1000 internet. And yet we only get good ratings for the speed. I find that many, that are sceptical about the shared bandwidth of GPON, forget that a typical POP might only be fed by a 10 Gbps uplink. Usually this has much lower bandwidth per user than the GPON link.
