Calient Networks Partners with Cornet Technology, Inc. to Expand Federal Networks Market Success.

Calient Fiber Optic Cross-Connection Systems in Demand for Both Government Networks and Commercial FTTX Networks.

SAN JOSE, Calif. -- Calient Networks, a leading supplier of carrier-class optical switching and fiber management systems, today announced an OEM agreement with Cornet Technology, Inc. (CTI), a leading communications solution integrator to the federal government sector, to provide Calient's new DiamondWave[R] FiberConnect system to key high performance networks.

Calient's FiberConnect represents a price and reliability breakthrough in fiber optic cross-connection systems (FOCS). The FOCS solution has experienced an order-of-magnitude cost decrease in the past two years through a series of manufacturing and design breakthroughs. Under the new partnership, CTI's Cornet Technology Communications division will market and sell Calient's FiberConnect FOCS solution under the name ClearWave to government and military agencies, thereby bringing the benefits of low-cost, sophisticated, and automated fiber management and test to these agencies' networks.

"The same low cost and high reliability features that make FiberConnect an ideal fiber management solution for carrier networks can also apply to government networks," stated Calient Networks CEO Charles Corbalis. "FiberConnect allows an operator to remotely monitor, test, restore, and reconfigure a fiber network, thereby dramatically streamlining the operations of increasingly complex networks. While this makes commercial FTTX deployments more economical and operationally viable, it also provides government networks with the high degree of reliability, access and flexibility required for mission-critical operations. With the recent rise in government and defense network requests-for-proposal, our newest partner, CTI, will be instrumental in helping Calient remain a leader in FOCS solutions deployed by this, their target market. CTI is a highly-respected integration expert in government applications, and we look forward to working side-by-side with them on these demanding opportunities."

"Calient is an outstanding technology partner for us in this area of growth," added Tom Bennett, president of Cornet Technology Communications, a Division of Cornet Technology, Inc. "Our companies' strengths are extremely well-matched, and CTI's track record of success with the agencies soliciting tenders in high-performance networking is very strong. This agreement further strengthens the broad range of network solutions that Cornet Technology can offer these sectors."

Calient's FOCS solutions have been deployed in commercial and government fiber optic networks since 2002. In addition to carrier Central Office environments, they are now being applied in the rapidly growing FTTX market to help service providers accelerate service delivery and create hands-free fiber provisioning. Mid-to-large scale carriers have asked Calient to help them address the growing mountains of unmanaged fiber resulting from the 30% growth/year in their fiber plants. The company has announced its entry into this market with a powerful solution set during the FTTH Conference, currently underway in Las Vegas, NV. The DiamondWave[R] FiberConnect is currently on display at Booth #250.
