AudioQuest designed the OptiLink-G to give you a distortion-free connection between your digital audio components like CD players, DVD players, and receivers. AudioQuest's cable designs are based on years of in-house research and careful engineering, to provide the best performance possible. Their OptiLink-G cables use a finely polished, low distortion polymer fiber to minimize signal loss and jitter (time-based distortion). A PVC inner jacket and braided nylon outer covering protect the fiber. Each plug also has a brass ferrule to reinforce the cable's connection, which helps ensure ideal light transmission, for the highest quality sound.
Since optical cables carry signals as pulses of light rather than as a stream of electrons, they are virtually impervious to magnetic or electrical interference.
