Like the well-proven Cherry Cola 18, Root Beer 18 is an active optical cable that provides outstanding audio/video performance at distances up to 100ft (30m). Optical Fiber eliminates multiple forms of degradation over distance; powered by the HDMI port, no AC adaptor is required. Further, Optical Fibers provide total RF immunity and galvanic isolation for the audio/video signal—important advantages in the fight against radio-frequency noise. As with Toslink and other optical cables, optical fibers do not pick up or transmit induced RF-Noise.

Additionally, Root Beer's eARC and communication conductors are Direction-Controlled to minimize RF Noise that hurts the performance of active circuits.

All AudioQuest High-Speed HDMI cables are capable of Ultra-HD 4K/60 or 8K/30 video. Multiple AQ value-added ingredients enable a surprisingly stronger audio/video experience.
