The XG-C100F network card delivers a high speed of 10 Gbit/s – next-generation performance up to 10 times faster than a gigabit network for rapid file transfers, smooth 4K streaming, and low-latency gaming. More power with fiber optics – the latest high-speed transmission technology enables data transfers over significantly longer distances than copper cables. An aluminum heatsink with a well-thought-out design ensures efficient heat dissipation and reliable continuous operation. The integrated QoS technology automatically increases bandwidth for important streams or games. With the SPF+ cage, DAC connections are also compatible.
