San Jose, California, February 14, 2006 – JDSU today announced that it has shipped more than 5,000 XFP transceivers to Force10 Networks for its TeraScale E-Series family of switch/routers.  Force10 leverages JDSU’s industry-leading transceivers to provide an unmatched level of 10 Gigabit Ethernet density in the TeraScale E-Series. 

“The smaller size, low power consumption and interface flexibility of JDSU’s XFP transceivers have enabled us to build industry-leading 10 Gigabit Ethernet densities into the TeraScale E-Series and, in turn, decrease per port prices,” said Sachi Sambandan, vice president of engineering at Force10 Networks.   “As adoption of 10 Gigabit Ethernet continues to increase, we expect to see more vendors move to XFPs in order to provide the high densities that will be required for ever-growing bandwidth demands.”

Leveraging the smaller size of JDSU’s XFP transceiver, Force10 built the industry’s only 16-port 10 Gigabit Ethernet line card.  Additionally, the lower power consumption of the XFPs over other transceivers enables the TeraScale E-Series to support an industry-leading 224 Ten Gigabit Ethernet ports per system.  Customers such as SEGA Corporation, FiberNet Telecom Group and Vonage have deployed the Force10 TeraScale E-Series, integrated with JDSU’s XFP transceivers, to increase the scalability of their high performance 10 Gigabit Ethernet networks.

“As the transition to 10G Ethernet networks accelerates, JDSU is well positioned with an XFP transceiver that enables valued customers like Force 10 Networks to achieve key requirements for their systems, including higher density, reduced power and improved cost-effectiveness,” said Mike Ricci, senior vice president of JDSU’s Components and Modules group.  “We look forward to continued support of the TeraScale E-Series, one of the most innovative Ethernet switching platforms in the industry.”

JDSU was first-to-market with 10G XFP transceivers, introducing the product more than two years ago and establishing it as a leader in the market.  They are multi-source agreement (MSA)-compliant, designed to offer a smaller size that reduces board space on line cards for optical networking systems and support multiple 10Gbit/s applications, enabling reduced network costs.
