Product Description

PCI Express Dual QSFP+ Port Fiber 40 Gigabit Ethernet Network Card  (Intel XL710BM2 Based)

LR-LINK LREC9902BF-2QSFP+, Dual QSFP+ Fiber 40 Gigabit Ethernet PCI Express network card is designed for Servers and high-end appliances. LREC9902BF-2QSFP+ offer simple integration into any PCI Express X8 to 40Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

LR-LINK LREC9902BF-2QSFP+ network card is based on Intel XL710AM2 Ethernet controller with two fully integrated Gigabit Ethernet Media Access Control (MAC) and XLPPI Interface. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers. Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.

LR-LINK LREC9902BF-2QSFP+ is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
