Solarflare Communications and Bel Fuse Partner for High-Density, High-Performance 10GBASE-T Solutions

10Xpress® transceiver coupled with MagJack® Magnetic Module deliver excellent insertion loss, return loss and crosstalk performance over 100 meter reach

Irvine, CA - July 07, 2009

Solarflare Communications, the leader in standards-based 10 Gigabit Ethernet (10GbE) silicon, and Bel Fuse Inc., (Nasdaq: BELFA and BELFB), a premier developer of magnetic-based solutions for high-speed networking and computer applications, today announced results from recent qualification of the Bel 1X1 integrated magnetics module (MagJack) with Solarflare’s 10Xpress 10GBASE-T PHY. Superior insertion loss, return loss and crosstalk performance were measured across 100 meters of Category 6A UTP copper Ethernet cabling, confirming the combined solution’s ability to support optimal network performance and reliability on high-density 24 port 10GBASE-T switches that are forthcoming from multiple OEMs in USA and Asia.

Data centers and enterprises will need to upgrade to 10 Gigabit networks in order to provide the high bandwidth needed to support advanced applications, such as virtualization and cloud computing, as well as the continuing convergence of LAN / SAN traffic. 10GBASE-T switches and server adapters are the most cost effective means to meet this need. 10GBASE-T solutions can easily and cost-effectively be deployed over both new Category 6A as well as installed Category 6 UTP copper Ethernet cabling.

“Bel’s new single-port LAN magnetics modules are the preferred choice for OEM design engineers to use with the latest generation of 10GBASE-T PHY chips,” said John Hess, Bel MagJack product line manager. “Solarflare’s testing proves that 10GBASE-T can easily support high-density, high-performance data services and higher-speed network switches and servers.”
