HICKORY, N.C.--(BUSINESS WIRE)--July 27, 2000

More than three million POTS splitters and distributed filters

shipped during first two quarters

Corning Cable Systems, an industry leader in broadband access technology, today announced that it has shipped more than 1.5 million full rate ADSL Plain Old Telephone Services (POTS) splitters and more than 1.4 million distributed filters worldwide during the first two quarters of 2000.

Corning Cable Systems has received extensive orders and requests for its POTS splitters, a passive device that splits POTS and data frequency on a twisted copper pair for wireline access technology. Corning Cable Systems' POTS splitter business has more than tripled compared to this time last year. Given this performance, Corning Cable Systems expects to ship at least 3 million full rate POTS splitters by year-end.

Corning Cable Systems is dedicated to providing access technology including fiber optic and copper cable and hardware solutions to customers around the globe.

"ADSL technology is one of many recent dramatic product offerings that will carry high-speed data from the central office to the home," according to Marty Curran, Corning Cable Systems Senior Vice President and General Manager of Hardware and Equipment Operations. "With more than 3 million product shipments already this year, this is evidence that Corning Cable Systems has the knowledge, the expertise, and most importantly, the experience to enhance the telecommunications industry. ADSL is today's enabling technology that will allow telco customers to have the world at their fingertips. Long-term, we're working on additional fiber products that offer high speed data, video, and voice communications."

Additionally, Corning Cable Systems has shipped more than 1.4 million distributed filters for use at the customer premises during the first two quarters of 2000. The distributed filter enables service providers to offer splitterless ADSL to customers. The distributed filter separates the data analog noise on a phone line that enables a subscriber to receive and make phone calls while connected to the Internet. The year-to-date shipment performance in 2000 positions Corning Cable Systems to ship nearly 4 million distributed filters by the year-end.

"Again, the demand for these products is indicative of our commitment to listening and responding to our customers," Curran said. "We consistently provide insights, solutions, and services. As a result, the Corning name has become synonymous with commercial telecommunications applications. ADSL technology is here and it is in the future of telecommunications products."
