QED Reference Optical Quartz Digital Lead

Reference Optical Quartz Cable

The Reference Optical Quartz cable is your gateway to exceptional sound quality, whether it's linking DACs, TVs, CD players, or Blu-ray players to amplifiers or receivers.

This cable exceeds the demands for high-definition multi-channel digital audio, boasting an impressive bandwidth of up to 12MHz.

In comparison to standard Optical cables, this bandwidth remains unaffected even when the cable is bent, ensuring consistent and superior performance.

Reference Optical Quartz offers more than double the bandwidth of single acrylic glass fibres and only 1/10th of the attenuation, making it a perfect choice for multi-channel setups or for enhancing stereo sound.

QED's Cutting-Edge Glasscore Technology

QED's innovative Glasscore technology revolutionizes the optical fibre design, employing ultra-fine boro-silicate glass optical fibres bundled together. These fibres, each less than 50um in diameter, collectively form a 1mm diameter cable conforming to the Toslink standard connectors. The minute size of the fibres ensures that light rays follow similar paths, vastly reducing timing errors, distortion, and jitter for improved data transmission accuracy.

Stepped Refractive Index for Enhanced Signal Guidance

Quartz fibres are coated with a cladding of low Refractive Index to effectively guide the light signal, enhancing the cable's performance.

Impressive 12MHz Bandwidth

The cable offers a staggering 12MHz bandwidth, exceeding the demands for high-definition multi-channel HD digital audio. Unlike conventional Optical cables, this bandwidth remains unaffected even when the cable is bent. Reference Optical Quartz provides double the bandwidth of single acrylic glass fibres and minimal attenuation, ensuring superior performance.

Ultra-Low Jitter and Loss

QED has achieved remarkable results, measuring Jitter or timing distortions in conventional optical cables at around 145ps. However, with Reference Optical Quartz, timing errors are significantly reduced, resulting in minimal distortion, jitter, and ultra-low loss of less than 0.03 dB/m.
