G.fast allows operators to define the upstream/downstream bandwidth ratio. Traditional fixed access technologies (such as GPON, EPON, and ADSL) provide higher downstream bandwidth than upstream bandwidth. For example, for ADSL2+, the typical downstream bandwidth is 2M-8M and upstream bandwidth is ...
