QED SUPERIOR TOSLINK OPTICAL DIGITAL AUDIO LINK CABLE MADE WITH REAL GLASS
Reference Optical Quartz is the first of its kind to consist of 210 individual boro-silicate glass fibers. The cable allows you to experience stunning sound when connecting DACs, TVs, CD players and Blu-Ray players to amplifiers or receivers because it has a much higher bandwidth and attenuation of only 1/10th of traditional acrylic fibers. The Reference Optical Quartz greatly exceeds the demands of high-resolution multi-channel digital audio with a bandwidth of over 150MHz, completely unaffected by cable kinking.
FEATURES AND BENEFITS
QED’s new Glasscore ™ technology uses multiple ultra-fine boro-silicate glass optical fibers (GOF), each no more than 50um, to form the required 1mm diameter to conform to Toslink standard connectors. Because the fibers are so small, the different paths taken by the light rays are similar in length, virtually eliminating timing error and providing less distortion and vibration. This affects the increased bandwidth and accuracy of data transfer.
STEP REFRACTIVE INDEX
Quartz fibers are coated with a low Index of Refraction coating to direct the light signal.
BANDWIDTH OVER 150 MHZ
This greatly exceeds the demands for high-definition multi-channel HD digital audio. Unlike conventional acrylic glass optical cables, quartz glass cables can transmit signals including 24bit / 192kHz with very low jitter.
Reference Optical Quartz can provide a much higher bandwidth than a single acrylic glass fiber with an attenuation of 1/10.
ULTRA LOW JITTER / ULTRA LOW LOSS
QED has calculated that jitter (distortion caused by timing differences between different light paths) in conventional optical cables can typically reach up to 145ps. In Reference Optical Quartz, timing errors are virtually eliminated, resulting in less distortion, jitter and ultra-low loss of <0.03 dB/m.

PMMA OPTICAL FIBERS
A typical optical fiber is made from an acrylic glass material known as PMMA (Polymethyl-methacrylate). This acrylic core allows light to travel many different lengths through it. Timing differences are introduced – typically to account for up to 145ps Jitter.
Signal losses occur when the light goes above the Critical Angle and is not reflected back (Yellow).
REFERENCE OPTICAL QUARTZ
Reference Optical Quartz, more than 210 Glasscore ™ each thinner than a human hair It has fiber. This provides ultra-low jitter because the smaller numerical aperture reduces the range of acceptance angles resulting in flatter signal paths.
GLASSCORE ™ TECHNOLOGY
Instead of using traditional low-performance polymethyl methacrylate (PMMA) plastic optical fibers (POF), which comes as a single 1 mm OD fiber, the cable consists of more than 210 boro-silicate glass optical fibers providing enhanced vibration performance and higher bandwidth capacity. (GOF).
ULTRA LOW JITTER
Jitter is the undesirable deviation from the true periodicity of a assumed periodic signal in electronics and telecommunications, usually in relation to a reference clock source. An ultra-low vibration cable
