Performance Optical Graphite

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 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.

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

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.

Very Low Loss

Very Low loss < 0.15dB attenuation per metre

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

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.
