Aurora Networks Expands Transmitter Products; Announces Four Lines of 1 GHz Transmitters.

SANTA CLARA, Calif. -- Aurora Networks announced it is now shipping a complete family of 1 GHz optical transmitters for broadcast and narrowcast applications. By delivering four lines of 1 GHz products for its highly flexible optical transport platform, Aurora has the extensive product breadth to meet existing and future customer needs.

All four modular transmitter product lines provide a 1 GHz transmission passband (46 to 1002 MHz). Among the many features of these lines are:

--  AT3550 series 1550 nm Broadcast Transmitters
        --  Optimized for NTSC 77-channel and PAL B/G 64-channel plans
        --  Transmission distances of 65 or 100 kilometers
        --  9.5 dBm minimum optical output power

    --  AT3510G series 1550 nm Narrowcast Transmitters
        --  42 different DWDM wavelength versions with 100 GHz channel
            spacing (channels 18 through 59 on the standard ITU-T
            G.694.1 grid)
        --  10 dBm optical output power

    --  AT3300G-E series 1310 nm Enhanced Performance Transmitters
        --  53 dB CNR (with full channel loading of 50-550 MHz analog
            and 550-1002 MHz, 256 QAM)
        --  -20 to +65 degrees Celsius
        --  Models with link loss budgets ranging from 2 to 14 dB

    --  AT3300G series low-cost 1310 nm Standard Performance
        Transmitters, including model options providing additional
        network flexibility:
        --  One all-band RF input port
        --  Dual RF input ports for individual broadcast and
            narrowcast inputs
        --  Dual RF input ports with automatic gain control (AGC)
        --  Patent-pending LCWDM options offering up to 8 wavelengths

"Cable operators are looking for innovative solutions to increase the capacity to each subscriber of their networks. But evaluating products from a variety of suppliers can be costly and time consuming," said John Dahlquist, Aurora Network's vice president of marketing. "By developing a robust line of 1 GHz transmitters that are available today, we can provide the widest range of solutions to cable operators for cost-effective extensions or network upgrades, including our patent-pending LCWDM transmitters."

The 1 GHz transmitters are key components of Aurora's industry-leading compact, densely-populated optical transport headend platform that enables cable operators to more easily deploy, monitor, and service headend components than similar solutions. The transmitters not only enable more bandwidth per cable subscriber--and hence more services--but are the launching point for the industry's widest range of transmission network solutions. They reliably accomplish both goals at a significantly lower cost.

Aurora Networks will showcase its complete line of 1 GHz transmitters at the Society of Cable Telecommunications Engineers' Cable-Tec Expo in Denver on June 21-23 in booth 571. Stop by the booth to ask for an evaluation product.
