Aurora Networks Launches Transmitter Designed to Expand Fiber Deep Narrowcasting Capability
Aurora Networks' new AT3520G DWDM Narrowcast Transmitter launches 50 percent more narrowcast channels

SANTA CLARA, Calif. — Feb. 9, 2009 — Aurora Networks, Inc., the only optical transport solution provider focused on delivering a cost-effective, optimized platform for next-generation cable services, today announced the AT3520G, a high-performance analog Dense Wavelength Division Multiplexing (DWDM) narrowcast transmitter designed to provide the narrowcast channels required by operators to support expanding and in-demand high-speed data (HSD), Video on Demand (VoD) and telephony services. By increasing the number of narrowcast channels carried on one transmitter, the AT3520G expands narrowband services without the need for additional transmitters in headend and hubs where space is constrained.

The AT3520G seamlessly integrates additional narrowcast channels into existing HFC and Fiber Deep architectures enabling MSOs to expand narrowcast channel capacity. MSOs simply replace existing AT3510G narrowcast transmitters to instantly access 50 percent more narrowcast channel bandwidth.

"The AT3520G gives MSOs the ability to immediately widen their service offerings, like VoD and high-speed data, without incurring major infrastructure costs," said John Dahlquist, vice president of marketing at Aurora Networks. "Aurora Networks is committed to helping the cable industry drive a deeper set of capabilities to the home while maintaining an approach with a clear cost advantage over the competition."

As on-demand, digital services rise in popularity among subscribers, MSOs, telcos and satellite pay-TV providers are vying for this business. The AT3520G solution gives MSOs a low cost solution to better compete with telco and satellite providers for subscribers.

The AT3520G is a module for the CH3000 platform and is supported by a full range of passive components along with Aurora Networks' industry-leading Light-Plex™ module. High-density, compact packaging permits network operators to install up to 14 transmitters per 3RU chassis, taking up less space and allowing for additional modules to enhance deployment of traditional HFC, Fiber Deep and fiber to the premises (FTTP) networks.

Additional information, including technical product details and visuals for Aurora Networks' AT3520G narrowcast transmitter, can be found at www.aurora.com . The AT3520G is now available for order and will begin shipping in early Q1 2009.
