About the QED Reference Optical Quartz Cable
Most optical audio cables use acrylic fibre. Reference Optical Quartz uses 210 separate boro-silicate glass fibres, each 50 microns across. QED say that gives a much higher bandwidth, over 150MHz, and about a tenth of the attenuation of acrylic fibres.
The bandwidth is not affected by bending the cable, and the fibre bundle is highly flexible. It has a stepped refractive index and is designed for ultra-low jitter, with compatibility for 24- and 32-bit high-resolution audio.
It sits in QED’s Reference range. Use it between a DAC, TV, CD player, Blu-ray player or games console and a receiver or amplifier with a Toslink input.

Questions about the QED Reference Optical Quartz Cable
Is it one cable?
Yes. It is a single optical lead with a Toslink plug at each end.
Is it more fragile than an acrylic optical cable?
It is a glass-fibre cable, so treat it with care, but QED describe the fibre bundle as highly flexible and say its bandwidth is not affected by bending.
Which length should I choose?
It comes in 0.6 m, 1 m, 2 m and 3 m. Measure between the two components and choose the next length up.
