Aurora Networks is touting its latest next-generation access solution for its node platform: the RQ4000-series "Remote QAM." The solution addresses both the capital and operational challenges cable operators face as they continue to increase narrowcast traffic to support the growing demand for more sophisticated video and data services.

Aurora combined its node expertise with the multiplexing and QAM modulation technology it acquired from GoBackTV in May to create a solution that enables cable operators to transition broadcast QAM and edge QAM functionality into the node.

Aurora Remote QAMThe new node QAM plugs into an Aurora optical node platform, configured either for Fiber Deep or traditional HFC. It supports up to 158 incremental QAM channels while connecting to Aurora's headend-based Universal Services Multiplexer via digital optical transport. In the absence of legacy analog and broadcast QAM signals, it enables the operator to move the digital/RF interface all the way to the node.

The Remote QAM module provides the higher QAM densities and operational improvements that are being sought by the Converged Cable Access Platform (CCAP) initiative, according to Aurora.

"Aurora Networks believes that the evolution of the node is essential to the future success of cable operators," said John Dahlquist, vice president of marketing at Aurora. "The Remote QAM module is a natural extension of our product line."

Aurora also has on display its recently expanded end-to-end PON portfolio, including the Trident7 technology it acquired with the purchase last summer of Enablence's PON product line.

The Trident7 is an IP optical access platform that supports EPON, point-to-point Ethernet and GPON OLT. Going forward, this system will be the central element for Aurora's advanced access network solutions, such as 10G EPON and BitCoax (EPON over coax).
