In a USB 3.0 cable, there are 9 different wires used. In the same, suppose we take the two differential pair wires (TX, RX) are used, which are in the range of 26-34 gauge. But I need to know what type of wire is used exactly inside? If I need to place an order what should I enter?

Thanks in advance,

Saurabh

  • \$\begingroup\$ Thanks for your reply, I have a USB 3.0 interface on my board where I can suggest the exact type of wires to be used for each signal, especially for the differential signals in my document. \$\endgroup\$

  • \$\begingroup\$ I guess the USB specification provides you with the mandatory parameters for the transmission lines + Power Supply... usb.org/document-library/… (just peeking into it: yes there are detailed specifications!) \$\endgroup\$

USB 3.0 cables are both common and specialized enough that you can directly search for that, and/or in a parametric search, select "2 pair + 4" as the desired number of conductors.
