SOMERSET, N.J. -- EMCORE Corporation (NASDAQ: EMKR), a leading provider of compound semiconductor-based components and subsystems for the broadband, fiber optic, satellite, and wireless communications markets, today introduces its PCI height compliant, small form factor 10GBASE-CX4 (CX4) module, which extends its portfolio of electrical domain products for the 10 Gigabit Ethernet (10GbE) market. This product offers 10GbE connectivity over electrical cables in an 11mm high X2 package. The CX4 module fully complies with the IEEE 802.3ak standard, X2 package multi-source agreement, and PCI card height requirements enabling new 10 gigabit enterprise data center, server and network attached storage connections. EMCORE’s CX4 module also provides an integrated media detect function, which provides compatibility with EMCORE’s SmartLink™ optical media converter, extending the transmission distance up to 300m. The new reduced-size X2 module is roughly half the size of the XENPAK units and supports topside mounting on the host PCB.

Charles Wang, Director of Module Development for EMCORE’s Fiber Optics Division, said, “We are seeing broad industry wide expansion of 10 Gigabit Ethernet. As the breadth and depth of systems expand, EMCORE continues to provide products which address the market’s need for innovative pluggable devices. EMCORE’s new CX4 units provide a robust, cost effective solution which compliments our other 10GbE electrical and optical XENPAK and X2 options.”

"Falling prices are key to the growth we expect in 10GbE NIC and iSCSI HBA shipments during 2005 and 2006," said Bob Wheeler, Senior Analyst at The Linley Group. "As a lower cost alternative to fiber, CX4 is helping to enable data center deployments of 10GbE in servers, switches, and IP-storage systems."

EMCORE’s CX4 transceiver provides 10GbE connectivity over standard electrical cables for distances up to 15m. As with all of EMCORE’s X2 products, this module provides full diagnostic, monitoring and control functions through the IEEE standard Management Data Input Output (MDIO) interface. The MDIO interface may be programmed with customer specific data to provide additional vendor control of modular interfaces in their system environment. This X2 module is available in PCI-height (11mm) and mid-height (13.46mm) versions.
