Industry-leading 10 Gigabit Single-mode Fiber Server Connection

The Intel® PRO/10GbE LR Server Adapter- the industry's second-generation 10 Gigabit Ethernet adapter-enables more productive networks with the fastest Ethernet connectivity available. The Intel PRO/10GbE LR Server Adapter delivers industry-leading performance to bandwidth-intensive applications using a highly integrated PCI-X Intel® 82597EX 133 MHz/64-bit 10GbE controller. High-speed server connectivity-once reserved for costly proprietary technologies such as high-performance computing clusters and grid-based computing-can now be achieved with the industry-standard Intel PRO/10GbE LR Server Adapter.

• Extends Ethernet distances up to 10 km
• Highly integrated PCI-X second-generation silicon for high performance
• Smaller form factor with XPAK Optical Transceiver fits in standard server PCI slot
