QED Reference Optical Quartz
Reference Optical Quartz is the first of its kind, consisting of 210 separate boro-silicate glass fibres.
The Reference Optical Quartz cable allows you to experience stunning sound when connecting DAC''s, TVs, CD Players and BluRay players to amplifiers or receivers.
Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of up to 12MHz.
In contrast to conventional Optical cables, this bandwidth is completely unaffected by bending the cable.
Reference Optical Quartz gives over double the bandwidth of single acrylic glass fibres and 1/10th of the attenuation so is ideal for use in multi channel set ups or for enhancing stereo sound.
This cable is available in the following lengths:
- 0.6M (QE3306)
- 1.0M (QE3310)
- 1.5M (QE3315)
- 2.0M (QE3320)
- 3.0M (QE3330)
QED''s new Glasscore technology employs multiple fibre bundles of ultra-fine boro-silicate glass optical fibres (GOF) of no more than 50um each to make up the 1mm diameter necessary to conform to the Toslink standard connectors. Because the fibres are so small the different paths taken by the light rays are similar in length virtually eliminating the timing error and introducing less distortion and jitter. This has the effect of increasing bandwidth and the accuracy of the data transmission.
STEPPED REFRACTIVE INDEX
The quartz fibres are coated with a cladding of low Refractive Index to guide the light signal.
This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional Optical cables, this bandwidth is completely unaffected by bending the cable. Reference Optical Quartz gives over double the bandwidth of single acrylic glass fibres and 1/10th of the attenuation.
ULTRA LOW JITTER / ULTRA LOW LOSS
QED have measured Jitter or distortions caused by timing differences between the light different paths in conventional optical cables typically at 145ps. In Reference Optical Quartz, timing errors are virtually eliminated introducing less distortion, jitter and Ultra low loss < 0.03 dB/m.
