    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 DAC's, TV’s, CD players and Blu-Ray players to amplifiers or receivers because it has double the 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 up to 12MHz which is totally unaffected by bending the cable.

    Glasscore Technology

    QED's new Glasscore™ technology employs multiple fibre bundles of ultra-fine boro-silicate glass optical fibres (GOF) of no more than 50um each 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.

    Stepped Refractive Index

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

    12MHz Bandwidth

    This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional optical cables, it is completely unaffected by bending the cable. Reference Optical Quartz gives over double the bandwidth of single acrylic glass fibres 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.

    "If you thought all optical cables were built the same then the QED will make you think again. Its enhanced bandwidth means there's never any problem passing a high-resolution digital signal. It sounds clear open and rhythmically authoritative. If you're looking for a good digital optical connection at a reasonable price then this glass cable is hard to beat." Hi-Fi World, September 2016
