Reference Optical Quartz

QED's superior Toslink Optical digital audio interconnect cable made with real glass

Reference Optical Quartz is the first of its kind, consisting of 210 separate boro-silicate glass fibres. The cable allows you to experience stunning sound when connecting DACs, TV's, CD players and Blu-Ray players to amplifiers or receivers because it has much higher bandwidth and only 1/10th of the attenuation of traditional acrylic fibres. Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of over 150MHz which is totally unaffected by bending the cable.

FEATURES AND BENEFITS

GLASS CORE TECHNOLOGY

QED's new Glasscore™ technology employs multiple fibre bundles of ultra-fine borosilicate glass optical fibres (GOF) of no more than 50um each to make up the 1 mm 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.

STEPPED REFRACTIVE INDEX

The quartz fibres are coated with a cladding of low Refractive Index to guide the light signal.

Over 150MHz BANDWIDTH

This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional acrylic glass optical cables quartz glass cables can deliver signals up to and including 24bit/192kHz with very low jitter.

Reference Optical Quartz can provide a much higher bandwidth than a single acrylic glass fibre with 1/10th of the attenuation.

ULTRA LOW JITTER / ULTRA LOW LOSS

QED has calculated that jitter (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.

OVERALL PERFORMANCE

Glasscore™ Technology

Instead of using traditional low-performance polymethyl methacrylate (PMMA) plastic optical fibres (POF) which come as a single 1 mm OD fibre the cable incorporates 210+ boro-silicate glass optical fibres (GOF) which give improved jitter performance and higher bandwidth capability. 24 & 32-bit high-resolution audio compatible.

Ultra-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 ultra-low jitter has been measured at typically 30ps.
