We may have fat fibre backbones (very fat, in fact), but your cable modem is connected via two RF channels, one up and one down, which are modulated differently, contended in different ways and of different widths.

All of which means that your upstream is narrower than your downstream. Nature of the technology - ADSL is the same, but for different reasons.
