| Re: So how will this differ? FIOS TV isn't really a "hybrid coaxial/fiber system", but they transmit TV on the fiber in the same way the cable MSO's do: namely, they take the whole ~700 MHz-wide cable signal, and analog modulate one of the fiber wavelengths with it. This way, they rolled out TV using a tried-and-true technology with available components. Internet access, VOIP, and other digital services are carried digitally on another light wavelength.
For IPTV, even TV is carried in IP packets digitally on the fiber. It gives them alot more flexibility in offering advanced VOD services, etc. | |

join:2006-10-26 Worcester, MA | wouldn't IPTV over fiber allow for greater bandwidth in general? since another wavelength can be used with relative ease because the equipment is pretty much already in place. | |
