QED's multi-award winning Toslink Optical digital audio cable. The award winning ‘Performance Graphite’ Optical cable allows you to experience superior sound quality when connecting DAC's, TV’s, CD players and Blu-rayTM players to amplifiers or receivers. Performance Optical uses a polymethyl methacrylate (PMMA) acrylic glass optical fibre to comfortably transmit the higher bandwidth signals demanded by today's multi-channel digital audio links. The cable is optimised for a 'very low jitter' design to reduce digital errors, making for a cleaner audio data transmission. Here at QED we are so confident about the performance of our product that we offer a lifetime guarantee.

Polymethyl Methacrylate (PMMA) acrylic glass optical fibre

This new optical fibre boasts half the signal attenuation per metre of the previous Performance model, which means ‘Performance Graphite' comfortably transmits the higher bandwidth signals for multi channel audio. For HD multi channel audio applications (over 12MHz) please see our Reference Optical Quartz cable

Very Low Jitter Design

At QED we have identified jitter or distortions caused by errors in the light transmission as a major factor in the deterioration of the audio signal. By incorporating precision cladding techniques jitter is reduced enabling a cleaner signal with better dynamics and a wider sound stage.
