For SDM, the technology uses the exact same Hybrid Fiber-Coaxial plant without changes. The change to subscriber equipment is a chip change that is targeted at the same costs as today's chips in mature quantities yield a $0 delta cost. Add $4-$7 to maintain backwards compatibility.
And then repeats:
An complete economic impact comparison requires understanding all the system changes required for and ETTH method vs the SDM method. Neglecting head end costs, SDM requires $0 changes in existing cable plant between the head end and the subscriber equipment.
The words "$0 change" seem to imply free, but in what way does that mean "you must replace all the consumer equipment and your head end equipment with new products, which happen to be licensed to my company"? All this means is that the SDM product will cost the same as current equipment. The increased bandwidth, of course, will come with its own costs. -dsr- ------------------------------------- You are subscribed as lists-ip () insecure org To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
