Business Editors/High-Tech Writers

STATE COLLEGE, Pa--(BUSINESS WIRE)--Oct. 21, 2003

C-COR.net Corp. (Nasdaq:CCBL), a global provider of broadband communications products, software systems, and services, today announced that the Company has signed an agreement with Alloptic, Inc., a privately-held, Livermore, California, company and a pioneer in the development and deployment of PON (Passive Optical Network) technology that operates at Gigabit speeds. Under the agreement, C-COR has exclusive rights to market FTTP (Fiber-to-the-Premise) systems (often referred to as FTTX--Fiber-to-the "X" or "Fiber-to-Anything"--systems) that incorporate Alloptic's PON technology to cable television MSOs (Multiple System Operators) in the U.S. and certain other countries, as well as other selected domestic and international market segments.

C-COR's FTT maX is an end-to-end fiber solution that leverages the Company's 50 years of customer dedication, broadband network integrity expertise, advanced optical transport equipment, and element management systems, and Alloptic's PON technology and Gigabit connectivity to provide high-capacity bandwidth and a simpler, more efficient, and less expensive network access for transporting voice, video, and data to the home or business over fiber optic networks. The FTT maX uses a PON approach to address the last mile of the communications infrastructure from the service provider's central office or headend directly into business or customer locations, a local loop that is currently a bandwidth bottleneck between metro-core systems and the end-user. By sending point-to-multipoint signals through a distributed topology of fiber optic cables and passive splitters, PON technology taps into the higher-bandwidth capacity of fiber for the local loop, while using passive devices to eliminate the maintenance and installation costs of active electronics. The FTT maX has potential applications for a variety of service providers seeking revenue opportunities from new subscriber services while holding the line on costs, including MSOs, incumbent local-exchange carriers (ILECs), competitive local-exchange carriers (CLECs), overbuilders, municipalities, independent home builders, and utilities.
