Scientific Atlanta Expands Prisma II Optical Platform, Adding 1GHz Capabilities


Prisma II analog optics platform density improvements will help enable service providers to squeeze more bandwidth while delivering advanced services

DENVER - SCTE Cable-Tec Expo 2006 - Scientific Atlanta, a Cisco company, today announced two new Prisma IITM analog optics products designed to deliver exceptional bandwidth management. With the introduction of its High Density Dual Analog Receiver and 1GHz High Density Narrowcast (QAM) Transmitter, Scientific Atlanta continues to optimize its existing platforms while simultaneously driving 1GHz product development. Today, 16 MSOs representing 23 sites and more than 21,000 plant miles have chosen Scientific Atlanta’s 1GHz platform as their bandwidth enhancement solution.

Designed to meet the challenges faced by cable and telecommunication service providers trying to manage multiple types of traffic across different multiple infrastructures, these innovative products provide the additional bandwidth necessary for resilient delivery of services.

These products leverage the success of Scientific Atlanta’s Prisma II analog optics platform - doubling the density in the existing chassis by deploying half-height modules and offering a high-density narrowcast transmitter capable of 1GHz bandpass. Accordingly, each Prisma II chassis is capable of supporting up to 52 reverse paths or 26 forward narrowcast transmitters, enabling more cost-effective node splitting to support future services. Both products also maintain a lower power consumption requirement of 7.5W per module versus prior models, maintaining the chassis requirement of no more than 15W per slot. This unique feature becomes increasingly important as the need for these products grows in tandem with burgeoning advanced interactive and on-demand applications, resulting in reduced hub space and increased power needs.

“These new products will help our customers keep pace and grow their networks in today’s dynamic industry, while reducing the rack space required in existing hubs or headends,” said Mark Palazzo, vice president and general manager, Metro Access Networks for Scientific Atlanta. “These latest additions to the Prisma II platform help provide future flexibility as the number of advanced video applications grows and service providers expand their product offerings. With the 1GHZ capability of our High Density Narrowcast Transmitter, our customers will be equipped to meet the ever-growing need for additional bandwidth.”

The jump to 1GHz offers significant advances in versatility, enabling the creation of a profitable high-definition programming tier to complement analog, digital, and voice and data tiers. Scientific Atlanta’s 1GHz solution helps provide future flexibility for networks as operators explore ways to optimize the capabilities of existing bandwidth and expand bandwidth capacity for new, revenue-producing interactive services.
