No I don't work for Verizon, I actually work for Motorola in their CMTS division, but was taken back by a poorly written. "750 MHz cable plant (90% of the country’s cable network miles) has a digital equivalent capacity of approximately 5 Gbps of bandwidth." Yeah...good luck at getting QAM64 through out the entire network...you'd be lucky to get that 1000 feet from the headend consistently! "But also unstated is the fact that FiOS also multiplexes (or combines the signals) to customers onto a shared trunk — they just do so in a different portion of their network. " Now there is car salesmen talk if I ever heard any. Simply put FiOS muxes at the CO where Cable has to mux at neighborhood...a big difference in understanding networking 101 and providing QoS throughout the network! Oh and what happens when customers start demanding more and more HDTV channels without the crappy compression artifacts that appear right now on Comcast network? Yeah...might as well kiss all that bandwidth for DOCSIS goodbye! Simply put Fiber cleans Cable clock in terms of bandwidth availability...don't ignore that fact.

Otherwise, why would a FTTH provider bother to diss DOCSIS 3.0? Probably because they know that the half of their footprint that will be untouched by FiOS has no chance against cable.
