Reference Optical Quartz is the first of its kind, consisting of 2010 separate boro-silicate glass fibers that allow you to experience stunning sound when connected to DAcs, TVs, CD players, Blu-Ray players and amplifiers or receivers. This is because of the much higher bandwidth and only one-tenth of the attenuation of traditional acrylic fibers. Reference Optical Quartz vastly exceeds the demands for high definition, multi-channel digital audio with a bandwidth over 150MHz, which is totally unaffected by bending the cable. It comes with a lifetime warranty, so you can count on quality performance for years to come!
Our new Glasscore™ technology employs multiple fiber bundles of ultra-fine boro-silicate glass optical fibers (GOF) of no more than 50um each to make up the 1mm diameter necessary to conform to the Toslink standard connectors. Because the fibers 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 increases 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
In contrast to conventional acrylic glass optical cables, quartz glass cables can deliver signals up to and including 24bit/192kHz with very low jitter.
Ultra Low Jitter / Ultra Low Loss
We have calculated that jitter (distortions caused by timing differences between the different light paths) in conventional optical cables can typically reach up to 145ps. With our Reference Optical Quartz, timing errors are virtually eliminated, which introduces less distortion, jitter and ultra-low loss (<0.03 dB/m).
