QED Reference Optical Quartz Digital Interconnects

Over 40 years of award winning expertise

A wealth of industry design and engineering expertise has helped to deliver Reference Optical Quartz, the first of its kind, a superior optical cable made with real glass.

Glasscore™ Technology

QED's new GlasscoreTM technology employs 210 individual quartz glass optical fibres to make up the 1mm diameter necessary to conform to the Toslink standard connectors. Because the fibres are so small, the different paths taken by the light rays are similar in length virtually eliminating the timing error and introducing less distortion and jitter. This has the effect of increasing bandwidth and the accuracy of the data transmission.

Over 150MHz bandwidth

This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional 5MHz acrylic optical cables, Reference Optical Quartz can provide a much higher bandwidth with ultra low jitter and 1/10th of the attenuation.

ULTRA LOW JITTER/ULTRA LOW LOSS

QED have calculated that jitter (or distortions caused by timing differences between the different light paths in conventional optical cables) could typically reach up to 145ps. In Reference Optical Quartz, timing errors are virtually eliminated, introducing less distortion, jitter and ultra low loss < 0.03 dB/m.

This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional 5MHz acrylic optical cables, Reference Optical Quartz can provide a much higher bandwidth with ultra low jitter and 1/10th of the attenuation.

Just listen

Our extensive listening tests comparing it against competitor products at much higher price points have astonished us! We urge you to compare it not only to your favourite cable but also alternative brands and models at any price!
