QED Reference Optical Quartz Cable – 2.0m

QED’s Reference Optical Quartz is the first of its kind, incorporating 210 ultra-fine boro-silicate glass fibres to form a superior digital optical audio interconnect cable. This innovative construction vastly exceeds traditional acrylic fibres by offering over 150MHz bandwidth and reducing signal attenuation to just 1/10th of conventional cables. The cable’s Glasscore™ technology ensures highly accurate signal transmission with virtually eliminated timing errors, distortion, and jitter—delivering unparalleled sound quality when connecting components such as Blu-ray players, CD players, and DACs to amplifiers. The stepped refractive index cladding enhances light guidance, further ensuring signal integrity. Compared to common PMMA-based optical cables, the Reference Optical Quartz demonstrates dramatically improved jitter performance, achieving ultra-low jitter levels below 30ps. It supports high-resolution 24 and 32-bit audio formats, making it ideal for premium digital audio setups.
