Eric FiOS vs. DOCSIS 3.0

Let me share a few thoughts here, for context to big Cable’s announcement:

 

  • Today Verizon can deliver (and is right now in field trials) 100 mbps to the home using our currently deployed BPON technology.  Although we can deliver 100 mbps, given current customer needs, the fastest we sell is 50 mbps.

 

  • We are beginning to deploy next-generation GPON giving us the capability to deliver data speeds four times faster than the BPON technology allows.  For Verizon this is not years away but now.

 

  • Cable's issue is not the modem in the home (demonstrated at the Cable Show).  The problem is the transport from the head end to the customers’ locations.   This is the reason cable modem speeds slow when use is heavy.  Comcast says it has more than 400 customers on some of its nodes.  If all those customers all demand service at the same time, congestion can develop.   With our architecture, each customer has a dedicated path from the home to our central switching office.

 

  • Cable must give up four analog channels (40 digital channels) to pull off this trick.  In Verizon's FiOS system, we deliver data independently of our TV delivery, so increasing data speeds doesn't cost valuable TV real estate.   With the increasing popularity of HD TV, that television space is even more precious.

 

  • Our high speed IP gets all the way to our set top box (STB) where it can then be integrated with the traditional video using the latest Verizon interactive media guide software.   Cable providers are using DOCSIS to get high speed IP to their modem/router, but not to their STB.  Our approach will provide very low latency that is critical for applications like on-demand gaming (a $2B $10B market by 2010).  We expect to be able to deliver a console game-playing experience over our network, not just “flash media” games that are available on cell phones or over the Internet today.

 

See CZ’s related post here, and don’t miss Cynthia’s thoughts, either.
