ADC and Calient Networks Announce Joint Marketing Agreement; New Calient Automated Fiber Management Solution Integrates Calient DiamondWave Optical Switches and ADC Fiber Distribution Frames

Business Wire, June 6, 2005

MINNEAPOLIS -- ADC (NASDAQ:ADCTD)(www.adc.com), a world leader in providing global network infrastructure solutions, today announced a Joint Marketing Agreement with Calient Networks, a leading carrier-class photonic switching systems and software provider. The agreement leverages expertise from both companies to create new solutions for fiber-intensive networks. A new product, marketed as the Calient Automated Fiber Management (AFM) solution, integrates Calient's DiamondWave(R) optical switch and ADC's fiber distribution frame technology. Both companies will showcase this solution at SuperComm in Chicago from June 7-9.

Developed jointly by ADC and Calient engineers, the Calient AFM solution addresses operational issues experienced in fiber-intensive networks such as central offices, data centers, and test facilities. Installing, managing, and maintaining thousands of fiber connections in these facilities can become time-consuming and error-prone when managed manually. The Calient AFM solution's scalable, low-loss photonic switching technology provides software-reconfigurable fiber connectivity, enabling service providers to remotely manage fiber infrastructure, configure the network, and localize faults. The result is quicker service provisioning, more accurate infrastructure records, and optimized utilization of valuable capital and human resources. The Calient AFM solution can scale to support 64 to 640 fiber terminations.

"ADC is pleased to partner with Calient to provide advanced optical distribution frames for fiber-intensive networks," said Tom Kampf, director of fiber product management for ADC. "ADC's technology enables the Calient AFM to accommodate high density requirements while ensuring fibers are protected and well-managed for long-term network performance and scalability."

"As new broadband technologies are deployed, the Calient AFM provides a mechanism to scale, manage and monitor services deployed across fiber access networks," said Ron Mackey, chief marketing officer for Calient Networks. "With ADC, Calient has fully automated the fiber distribution frame and enabled rapid growth, reliability, and operational efficiency for high-performance optical networks."

The Calient AFM solution featuring ADC's fiber distribution frame technology is available today. To learn more, contact sales@calient.com.
