The Lekuo PR27F11 is a high-performance 10-gigabit fiber network adapter powered by the Realtek RTL8127 chipset. Designed for enterprise data centers, NAS storage systems, and high-bandwidth server applications, this card delivers true 10Gbps fiber optic connectivity through a standard SFP+ interface with industry-leading 1.79W ultra-low power consumption.
ULTRA-LOW POWER CONSUMPTION: INDUSTRY-LEADING 1.79W At just 1.79W during 10GBASE-R operation, the PR27F11 consumes 75-80% less power than comparable Intel X520/X710 SFP+ cards (7-10W typical). This translates to: - Lower heat output (passive cooling sufficient, no fan required) - Reduced electricity costs for 24/7 server operation - Extended component lifespan due to minimal thermal stress - Ideal for thermally-constrained environments and dense server racks
LONG-DISTANCE FIBER CONNECTIVITY: BEYOND COPPER LIMITATIONS Unlike 10GBASE-T copper cards limited to 100 meters, the PR27F11 with SFP+ fiber modules enables: - 300 meters with OM3/OM4 multimode fiber (10GBASE-SR) - 10 kilometers with OS2 single-mode fiber (10GBASE-LR) - 40 kilometers with extended-reach modules (10GBASE-ER) - 80+ kilometers with ultra-long-reach ZR/ZX modules
This makes it the ideal solution for inter-building connections, campus networks, data center rack-to-rack cabling, and metropolitan area networks where copper cannot reach.
