Straightwire digital cables have many of the same design requirements as high quality video cables such as accurate impedance with little variation over the relevant frequency range and great shielding to prevent unwanted interference. Issues of minimizing reflections and phase angle are also important for high quality digital cables.

The use of premium insulation for high velocity of propagation and minimal absorption is mandatory for consistent good performance. Terminations (both the connectors and methods of attachment to various cables) are critical to obtaining favorable results.
