Cisco's Scientific Atlanta Previews D-PON Architecture

Cisco's Scientific Atlanta announced a new DOCSIS Passive Optical Network (D-PON) architecture designed to enable operators to deploy cable-centric/cable-friendly fiber-to-the-home (FTTH) technology.



The D-PON solution, which is especially designed for greenfield developments, features a 32-way split PON infrastructure. Scientific Atlanta said its design enables cable operators to create an effective optical budget in both directions. Downstream, the D-PON uses 1550nm technology to provide cost-effective forward optics to get to the side of the home. For the upstream traffic, technology developments at the optical network terminal (ONT) location will provide a cost effective way to support very long distances.



"We see the D-PON architecture as a valuable and cost-effective solution for cable operators as they respond to the fiber-to-the-premise requirements that most residential and commercial developers are defining for new planned communities and multi-use facilities," said Mark Palazzo, vice president and general manager, Transport and Access Networks for Scientific Atlanta.
