The use of heat sinks reduces temperature of , protects card, works stably, and has a service life. Using for 82599 chip, multi-core processor server design, scalable virtual and unified storage. The external is fully shielded with gold-plated interface, which effectively reduces contact resistance and improves signal interference prevention. Thickened electric gold has high hardness, more wear-resistant than ordinary electric gold, better contact, can be plugged and unplugged ten thousand , and has better performance. 10 Gigabit single-port SFP server optical fiber network card, 6-layer PCB, stable and full-speed 10 Gigabit.
