Aurora Networks, a provider of innovative solutions that build future-proof networks for cable subscribers, announced has released its Universal Digital Return technology.

The Universal Digital Return technology enables cable operators to double their return path capacity using the recently reclaimed broadcast television spectrum.

Aurora Networks developed the Universal Digital Return to address the growing demands for more bandwidth in the upstream.

“With the demand for more upstream capacity, Aurora Networks has innovated to cost-effectively remove this bottleneck and still meet the ever-increasing upstream performance requirements,” said John Dahlquist, vice president, marketing, Aurora Networks, in a statement.

“The beauty of digital return technology is the independence of RF loads and required laser performance. Digital return technology provides operators with a cost-effective pathway to meet performance requirements that are currently not achieved by today’s upstream analog lasers,” Dahlquist added.

The Universal Digital Return module utilizes the 54-88 MHz spectrum. It expands the upstream bandwidth to 5-85 MHz, doubling standard North American offering of 5-42 MHz, offering benefits to customers.

Digital return will help customers achieve high link performance required by a fully loaded 5-85 MHz upstream pass band and utilizing 64-QAM DOCSIS 3.0 upstream bonded channel technology, independent of distances beyond 100 km.

Recently, Aurora Networks announced its deal to acquire GoBackTV (News - Alert), a provider of digital video headend solutions and edge QAMs. GoBackTV has approximately 20 employees that will be integrated into Aurora Networks’ Santa Clara campus.
