QED

The QED Reference Optical Quartz is a high-performance Toslink digital audio interconnect cable designed to deliver superior sound quality by connecting devices such as DACs, TVs, CD players, and Blu-ray players to amplifiers or receivers. Utilizing 210 separate boro-silicate glass fibers, it offers higher bandwidth and significantly lower signal loss compared to traditional acrylic fibers.

Key Features

• Glasscore™ Technology: Employs multiple bundles of ultra-fine boro-silicate glass optical fibers, each no more than 50 microns in diameter, to enhance data transmission accuracy.
• Stepped Refractive Index: Quartz fibers are coated with a low refractive index cladding, effectively guiding the light signal and minimizing signal loss.
• High Bandwidth: Supports over 150 MHz, exceeding the demands of high-definition multi-channel digital audio.
• Ultra-Low Jitter and Loss: Virtually eliminates timing errors, achieving jitter levels as low as 30 picoseconds and attenuation of less than 0.03 dB/m.

Use Cases

• Blu-ray Players, DVD Players, Digital Set-top Boxes, Game Consoles, CD Players: Provides superior sound quality by connecting these devices to receivers or AV amplifiers.
• Receivers, AV Amplifiers, DACs: Ensures optimal audio performance with high-definition signals.

Detailed Description

Glasscore™ Technology

The Glasscore™ technology utilizes 210 ultra-fine boro-silicate glass optical fibers, each no more than 50 microns in diameter. This design minimizes timing errors and reduces distortion and jitter by ensuring that light rays take similar length paths, enhancing bandwidth and data transmission accuracy. The cable is highly flexible, ensuring ease of installation and durability.

Stepped Refractive Index

The quartz fibers in the cable are coated with a low refractive index cladding, effectively guiding the light signal and ensuring minimal signal loss, thereby maintaining the integrity of the transmitted audio.

High Bandwidth

The QED Reference Optical Quartz cable boasts a bandwidth exceeding 150 MHz, allowing it to handle high-definition multi-channel digital audio signals, including those up to 24-bit/192 kHz.

Ultra-Low Jitter and Loss

Conventional optical cables can experience jitter up to 145 picoseconds. The QED Reference Optical Quartz cable significantly reduces this to less than 30 picoseconds, ensuring a cleaner and more precise audio signal. Additionally, the cable features ultra-low loss levels of less than 0.03 dB/m.
