Aurora Networks Announces Next Generation of Optical Transmitters
New Devices Increase Network Capacity at Lower Cost

Santa Clara, CA — June 15, 2006 — At the Society of Cable Telecommunications Engineers' (SCTE) Cable-Tec Expo in Denver on June 21-23, Aurora Networks will announce it is now shipping its line of AT3300G series 1 GHz 1310nm optical transmitters. These low-cost broadcast and narrowcast transmitters enable cable operators to reduce the cost structure of their network deployments as well as increasing both subscriber services and the number of subscribers serviced.

Four versions of low cost 1 GHZ transmitters are available, offering:

•  One all-band RF input port
•  Dual RF input ports for broadcast and narrowcast inputs
•  Dual RF input ports with automatic gain control (AGC)
•  Patent-pending fully-featured LCWDM versions

"With digital simulcast, VOD, VoIP and HDTV services gobbling up network resources, cable operators are under intense pressure to increase the capacity of their networks. But the competitive nature of this market demands that they control expenditures," shared John Dahlquist, Aurora Network’s vice president of marketing. "Aurora’s new one gigahertz transmitters help solve this dilemma by delivering a 16 per cent increase in bandwidth at 20 to 30 per cent lower cost than our previous generation of 870 megahertz transmitters."

AT3300G series transmitters are key components of Aurora’s industry-leading high density optical transport platform that enables cable operators to more easily deploy, monitor, and service their headend transmission systems when compared to similar product offerings. These transmitters not only provide more bandwidth per cable subscriber — and hence more services — but they also increase network flexibility by offering additional features, such as its revolutionary LCWDM technology, dual inputs (one for broadcast services and one for narrowcast services) and AGC options, while maintaining Aurora’s other advanced features. The AGC version has a unique AGC ''learn'' feature which enables the transmitter to be quickly set to the new optimal operating point after changing the channel loading conditions.

The AT3300G series delivers 1 GHz transmission bandwidth (46-1002 MHz) and features:

•  LCWDM versions offering up to 8 wavelengths
•  Seven optical output power options ranging from 3 to 13 dBm
•  Wide operating temperature range with guaranteed performance
•  Industry’s highest packing density (14 DFB transmitters in a single 3RU chassis)
•  Advanced predistortion circuitry for maximum performance per price
•  Dynamic back plates to simplify installation and maintenance.

Aurora will showcase its AT3300G series 1 GHz transmitters at the Society of Cable Telecommunications Engineers’ Cable-Tec Expo in Denver on June 21-23 in booth 571.
