The LR-LINK Single Mode Fiber Lan Card LREC6220PF-LX 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 1000Base-LX PCI Express x1 fiber nic for desktop use by Shenzhen Lianrui Electronics CO.,LTD.

Industry-leading performance

The LREC6220PF-LX Gigabit Ethernet Single Mode Fiber Lan Card 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 Single Mode Fiber Lan Card LREC6220PF-LX enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team.

LR-LINK LREC6220PF-LX Gigabit Ethernet Single Mode Fiber Lan Card 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.

LREC6220PF-LX Single Mode Fiber Lan Card is single SC connector fiber adapter, has 1000Mbps SC module.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 of the Intel 82575EB server chipset can support more functions

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,due to 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

Single Mode Fiber Lan Card Support PXE, WOL

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

Standard Features

Host Interface standard support PCI Express 2.0a
