QED Performance Optical Cable

QED Performance Optical Cable

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, TVs, CD players and Blu-rayTM players to amplifiers or receivers. Performance Optical uses a polymethyl methacrylate (PMMA) acrylic glass optical fiber to comfortably transmit the higher bandwidth signals demanded by today's multi-channel digital audio links. The cable is optimized 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.

FEATURES

Polymethyl Methacrylate (PMMA) acrylic glass optical fiber. This new optical fiber boasts half the signal attenuation per meter of the previous Performance model, which means 'Performance Graphite' comfortably transmits the higher bandwidth signals for multi-channel audio.

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.

CABLES MATTER

The new, award winning 'Performance Graphite' Optical cable utilizes the superior PMMA acrylic glass optical fiber previously only available in our 'Reference' range products.

The new optical fiber boasts half the signal attenuation per meter of the previous model, which means 'Performance Graphite comfortably transmits the higher bandwidth signals demanded by today's multi-channel digital audio links.

The cable features a stepped refractive index core that together with precision cladding techniques minimizes light absorption and modal dispersion of single mode optical signals at the fiber boundary.

This reduces the angle of incidence at which total internal reflection occurs so that more rays can propagate along the cable, which in turn makes for decreased jitter and improved audio data transmission.

OVERALL PERFORMANCE

Very Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying very low jitter has been measured at typically 50ps.
