Quartz glass fibers carry the picture, which AudioQuest says provides outstanding audio and video performance at distances up to 100 feet, or 30 meters. The HDMI port powers it, so no adapter is needed. It carries the full 18Gbps.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eQuartz Glass Fibers, Powered by the HDMI Port\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAudioQuest says optical fiber eliminates multiple forms of degradation over distance. Root Beer's quartz glass fibers carry the audio and video signal as light, and electro-optical modules in the plugs convert it at each end. Power comes from the HDMI port, so no AC adaptor is required.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eTotal RF Immunity and Galvanic Isolation\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAudioQuest says optical fibers provide total RF immunity and galvanic isolation for the audio and video signal, important advantages in the fight against radio-frequency noise. As with Toslink and other optical cables, the fibers do not pick up or transmit induced radio noise, no matter how long the run.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe copper that remains, the eARC and communication conductors, is controlled for direction.

HDMI is the flat 19-pin plug on every TV, projector, receiver and console. One cable carries picture, sound and the control signals that let the devices talk. The conversion modules live inside the plugs.
