Business Editors

MINNEAPOLIS--(BUSINESS WIRE)--May 31, 2000

ADC (Nasdaq: ADCT; www.adc.com) today announced availability of two new deep fiber nodes in the proven Optiworx ISX platform for advanced HFC networks. Optiworx ISX3025, an optical distribution node for mini-fiber node and collector node applications, and Optiworx ISX2025, a node for passive coax applications, will be debuted at SCTE's Cable-Tec Expo 2000, June 4-7, 2000 at the Las Vegas Convention Center.

Combined with the existing ISX3040 and ISX3022 Power Domain Node, the ISX3025 Deep Fiber Node and ISX 2025 Passive Coax Node provide the broadest range of nodes available in the market, delivering feature-rich yet cost-effective solutions for advanced service broadband HFC networks.

The Optiworx ISX3025 Node provides a flexible deep fiber node platform ideally suited for serving 70 to 250 homes. It features up to three outputs to significantly reduce amplifier requirements. The ISX3025 also offers multiple return path transmitter options that save both space and money, including the following: return RF amplifier modules that reduce fiber requirements in collector node architectures, digital return optic transmitters, and ITU grid DWDM return optic transmitters that further increase return traffic aggregation. The optional, state-of-the-art Optiworx Digital HFC return transmission system provides 100% bandwidth expansion and extended network reach by providing two independent 5-42 MHz RF signal streams on a single fiber from node to hub/headend. The ISX3025 is scheduled to be available in late summer 2000.

The second new Optiworx node is the ISX2025 for passive coax HFC network applications that deliver very high bandwidth per subscriber. Designed for 24 to 125 homes passed, the ISX2025 features up to two high level RF outputs as well as multiple return path transmitter options.

The ISX2025 features a small housing for ease of pedestal mounting and plug-in diplex filters for bandpass flexibility and easy migration towards packet data centric networks via simplified network bandwidth reconfiguration. The ISX2025 is scheduled to be available in late summer 2000.

"The Optiworx family of deep fiber node products brings space and capital saving options to broadband HFC network operators without compromising on functionality and performance," said Randy Schmid, director of marketing, ADC's Cable Transport Systems Division. "These products are just the first of a series of new, feature-rich deep fiber nodes and Digital HFC products planned to be introduced this year that demonstrate ADC's design and engineering leadership in providing advanced broadband HFC network solutions.
