Cisco's Scientific Atlanta unit is introducing what it is calling D-PON, which is a PON based FTTP system that fits into existing cable HFC networks. D-PON will enable providers to provide an alternative to the telco G-PON FTTP offerings for greenfield application from Verizon and ATT. This system will be available in the fourth quarter of 2007.
Motorola has offered a similar PON based system for cable companies, so the two main U.S. cable architectures will support PON FTTP access. This is another of the growing numbers of arrows that the cable companies can add to their quiver to counter the IPTV offerings from Verizon and ATT.
