Supra Cables Excalibur USB 2.0

Supra have recently been developing an ultimate USB Cable, and the result is USB Excalibur.

The goal was simple: to make the world's best USB cable, with no compromises or shortcuts. Excalibur is a premium high speed cable with improved data and power transmission, a complement to the existing Supra USB series models.

Both the data pair and the power pair are optimised for their purpose, as the demands to transmit data and power are different. The twisted data pair is made of PE insulated Silver-plated Oxygen Free Copper wires. The Silver layer is very thick, 3.8% of the total wire, for best conductivity and high velocity factor. Silver is great for high frequencies and high speed data transmission.

The construction of the power conductors are totally different compared to the data pair. To avoid power losses and to maximize the conductor area, Supra have used 4 tin-plated OFC wires in a star-quad configuration. The combination of Star Quad design plus separate screen greatly reduces any RF interference.

The USB plugs are siblings to Supra's popular HDMI plug. Fully shielded in aluminium. These plugs are detachable to make it possible to route the cable within 16 mm conduits including the contact. No more on-site cut-offs and re-soldering, jeopardising the typical Supra top notch performance.
