Intel 82575 Chipset PCIe 1000Mbps DUAL 2 SFP Port Server Lan Adapter Card

LREC9722PF-2SFP PCI Express x4 Dual Port SFP Gigabit Server Adapter (Intel 82575 Based)


Improved the power solution,use the TI high power management controller,more stable and low heat

Optimize designation, improved the distribution line,the strict control for Differential Signal,the error under 5mil

Use the 6 layer PCB,double copper thickness,5OZ heavy gold plate


LREC9722PF-2SFP is R&D PCI-Express x4 1000Mbps Dual SFP port server ethernet network fiber adapter card by Shenzhen Lianrui Electronics CO.,LTD(LR-LINK). The LREC9722PF-2SFP server network adapter card design for servers and high-end equipment, and the performance is optimized, make the system I/O is no longer a high-end bottleneck. LREC9722PF-2SFP can realize fault tolerance by bundling group, communication from fault port will be routed to the other members.
LREC9722PF-2SFP is pcie dual Port server network adapter,it can multiport fiber connecting to improve internet fuctions,at the same time,it will save PCI-Express slot.In the fiber gigabit network,PCI-Express I/O can ensure the fuctions,and save the bus bandwidth.
