Aurora Networks combats RFoG optical beat interference

Aurora Networks, Inc. has unveiled what it asserts is the first and only RF over glass (RFoG) system with a built-in, standards-compliant means to combat optical beat interference (OBI).

The company is showing off the new technology in booth O9 at this week’s ANGA COM event in Cologne, Germany.

OBI can occur in RFoG systems when two return transmitters hit a receiver simultaneously on the same wavelength, a condition that can easily happen in multiple-dwelling unit (MDU) applications of DOCSIS-based systems with their bonded upstream channels. Aurora Networks says that it has developed a signal conditioning technology, which it has trademarked as OBI-free, that combats these effects in a way that maintains use of the wavelengths specified within the RFoG standard.

As a result, cable MSOs can deploy DOCSIS 3.0 services via RFoG with minimal or no penalties, Aurora asserts. The fact that the system remains on the standard RFoG wavelengths also ensures a smooth migration to PON if the operator desires, the company adds.

“Operators need a simple solution for a complex problem: the ability to add more bandwidth, while ensuring the highest quality of service,” said John Dahlquist, vice president, marketing, Aurora Networks. “Aurora Networks continues its path of innovation with the first and only standards-compliant OBI-free RFoG solution that equips operators with the right tools to overcome this challenge.”
