This High Performance Digital Audio Optical Toslink Cable is engineered for high-capacity signal delivery to digital audio/video systems for crystal clear sound, better definition and true clarity. It is specifically engineered for digital signal data transmissions by using state of the art fiber optics. The optical signal offers more digital information at a higher speed and only a cable manufactured with fiber optics will provide this extra data signal transferring. Because the information is converted into light impulses that are sent over the fiber optic cable, the signal is immune to RF or magnetic interference. It is designed for the highest quality signal transfer in digital components by using Toslink to Toslink optical connections. Fiber optic Toslink connections are used on high-end stereo equipment and output connections are most commonly found on receivers, HDTVs, Blu-ray players, DVD players, XBOX 360 systems, Playstation 3 systems, Satellite & Digital TV Set-top-boxes and more.
