LREC6220PF-SFP PCIe x1 1000Base-FX Intel Processors SFP Port Fiber Network Interface Card NIC(Intel 82575EB Based)


The LR-LINK LREC6220PF-SFP sfp port lan card is a high performance PCI Express multifunction network adapter for either standard or low profile slots running over a fiber-optic network environment. Based on Intel 82575EB controller.It is a PCI Express x1 fiber nic for desktop use by Shenzhen Lianrui Electronics CO.,LTD.

Industry-leading performance

The LR-LINK SFP Port Lan Card LREC6220PF-SFP Gigabit Ethernet PCI Express adapters solution is designed for high-end appliances. The performance is optimized so that system I/O is not the bottleneck in high- performance networking applications.

Reliability, Availability, Serviceability

The LREC6220PF-SFP sfp port lan card enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team.

LR-LINK SFP Port Lan Card LREC6220PF-SFP Gigabit Ethernet PCI Express adapters have an integrated hardware acceleration that performs TCP/UDP/IP checksum offload and TCP segmentation. The host processing offloads accelerators frees CPU for application processing.

L LREC6220PF-SFP sfp port lan card is single SFP connector fiber adapter. It can be available to choose the MM or SM according to customers requirements.And The Intel 82575EB server controller,has the high performance,high stable,high quality and best compatible.It can compatible all the brand computers and fiber switches in market.It is the good solution for the high-performace FTTD applications.


Use the Intel 82575EB server chipset,can support more fuctions

Compatible all the OS

PCB 4 layer,1.5oz,4mil,more stable,longer using time,smaller resistance

Three line power : 3.3V/2.5V/1.0V,the directly power supply,the card will not be effected by the outside power flowing,more stable working enviroment

All use the good quality materials

SFP Port Lan Card Support PXE,WOL

Use the TI ,LT power controller,the best controller manufactures in the world,it can provide a stable working enviroment

Standard Features
