QED Reference Optical Quartz Toslink Digital Interconnect Cable

Reference Optical Quartz Toslink Dgital Audio Interconnect Cable, by QED. The first to be 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 a 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 150 MHz which is totally unaffected by bending the cable.

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 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.

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

Over 150 Mhz bandwidth capacity 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.

Digital Optical Audio cables are now used widely to connect audio source equipment such as TV's, CD players and Blu-Ray players to amplifiers or receivers. There are many advantages to using the optical output from your source equipment. The optical output provides complete electrical isolation between equipment eliminating ground loops and noise induced by large external voltages or currents. With fast digital signalling using twisted pair copper cables, problems such as near end crosstalk can cause distortion of the signal; these problems are eliminated by using the digital optical connection option.
