The black Premium Cat7 Double-Shielded 10Gb 600 MHz Ethernet Cable from Tera Grand is 75' long and rated for transmission frequencies up to 600 MHz, making it suitable for 10 Gigabit Ethernet environments. Tera Grand has shielded each pair of wires with aluminum Mylar foil and then bundled these pairs with an 85% tinned copper braid to improve noise resistance, almost completely eliminating alien cross talk (AXT). Moreover, the RJ45 connectors have 50 micron of gold plating for protection against EMI/RFI interference.
