Supra EXCALIBUR USB2.0 A-B cable

Supra EXCALIBUR USB2.0 A-B cable

Excalibur is a top-tier USB cable with enhanced data and power transmission, ideally complementing Supra's current, highly popular USB range. Both the data pair and the power pair are optimized for their respective purposes. The twisted data pair is made of PE-insulated silver-plated copper conductors. The silver layer is very thick, 3.8% of the total conductor, ensuring the best conductivity and a high velocity factor. Silver is excellent for high frequencies and fast data transfer. The construction of the power conductors is completely different from the data pair. To avoid power losses and maximize the conductor's surface area, Supra uses four tinned conductors in a star formation. The star construction and separate shielding significantly reduce susceptibility to RFI effects. The USB connectors are descendants of Supra's acclaimed HDMI connectors. They are fully shielded with aluminum, and the connector body is detachable, allowing the cable to be routed through 12-millimeter conduits - without detaching and damaging the contacts of the high-quality factory termination! This means no on-site cuts and re-soldering that would compromise the high-end performance typical of Supra.

Supra's digital cables are without exception designed to perform perfectly in their operating environments. Unlike basic market cables, Supra's USB cables are precisely impedance-matched, resulting in vanishingly low jitter, so the signal is always transferred unchanged and on time from one device to another.

Supra knows how to match impedance, how to design a conductor with desired low capacitance, and thanks to this expertise, Supra continues to win tests year after year. The technology is not veiled in mysticism or explained as rocket science; instead, all work stages and material choices are based on best practices and extremely high tolerances.
