Features: 1. Adopt original For INTEL chip - high performance master control chip, more stable&compatible then common chip with longer lifespan. 2. Filter - stably handle the filtering line interference, significantly extend network cable transmission distance. 3. RJ45 interface - external: all shielded gold-plated interface; internal contact: gold-plated 25mm flat needle to effectively reduce contact resistance, improve signal anti-interference ability, provide smooth data transmission. 4. Large heat sink - better heat dissipation effect, guarantee long working time. 5. Thickened connecting finger - more reliable contact and stable transmission, very few data package loss and data distortion. 6. Thousands of plugging and unplugging, suitable for PCI-Ex1, x4, x8, x16 slot.
