The XG-C100F network card delivers high speeds of 10 Gbit/s – next-generation performance, up to 10x faster than a Gigabit network for quick file transfers, smooth 4K streaming, and low-latency gaming. More power with fiber optics – the latest technology for high-speed transfers allows data transmission over significantly greater distances than with copper cables. An aluminum heatsink with a thoughtful design ensures efficient heat dissipation and reliable operation without interruptions. The integrated QoS technology automatically prioritizes bandwidth for important streams or games. The SPF+ cage is also compatible with DAC connections.
