Extends the length of your USB device cable to your hub, PC, or Mac. Perfect for devices with short cables. 24K Gold Plated Corrosion-Proof connectors maximize conductivity. Fast, 12 Mbits/sec transmission speed. 24K gold plated corrosion-proof connectors maximize conductivity. Tactilite molded strain relief provides a 360-degree turning radius for true protection against damage to the conductors. HotPluggable. Fully compatible with the PC. Gold plated copper connectors provide maximum conductivity and minimize data loss. Foil and braid shield complies with fully rated cable specifications reducing EMI/FRI interference. 20-gauge, double shielded, power wire conductor construction. Impedance matched twisted pair construction to minimize cross talk, ensuring high-speed, error-free transmission. Undermold shield helps to prevent radio frequency and electro-magnetic interference (EMI/RFI). Hood shielding eliminates antennae excitation.
