QED’S MOST AWARD-WINNING TOSLINK OPTICAL DIGITAL AUDIO CABLE
Award-winning “Performance Graphite” Optical cable lets you enjoy superior sound quality when connecting DACs, TVs, CD players and Blu-rayTM players to amplifiers or receivers. Performance Optical uses a polymethyl methacrylate (PMMA) acrylic glass optical fiber to comfortably transmit the higher bandwidth signals demanded by today’s multi-channel digital audio connections. The cable is optimized for a ‘very low jitter’ design to reduce digital errors and provide cleaner audio data transmission.

FEATURES AND BENEFITS
POLYMETHYL METHACRYLATE (PMMA) ACRYLIC GLASS OPTICAL FIBER
This new optical fiber has half the signal attenuation per meter of the previous Performance model, meaning ‘Performance Graffiti’ comfortably transmits higher bandwidth signals for multi-channel audio. For HD multi-channel audio applications (over 12MHz), please see Reference Optical Quartz cable
VERY LOW JITTER DESIGN
QED, we identified flicker or distortions caused by errors in light transmission as a major factor in audio signal degradation. Combining precision coating techniques reduces vibration and provides a cleaner signal with better dynamics and a wider soundstage.
VERY LOW LOSS
Very low loss <0.15dB attenuation per meter
Plastic Optical Fiber (POF) core made of acrylic glass
Graduated refractive index
Fluorinated Polymer Coating Material
24K gold plated Toslink connectors
Precision engineered plug
Attenuation ‹0.15dB / m (650 nm)
Numeric Aperture 0.5

WHAT IS THIS CABLE USED FOR
CABLES ARE IMPORTANT
|The new, award-winning ‘Performance Graffiti’ Optical cable uses premium PMMA acrylic glass optical fiber previously only available in our ‘Reference’ range.|
The new optical fiber has half the signal attenuation per meter of the previous model, meaning that ‘Performance Graffiti’ comfortably transmits the higher bandwidth signals demanded by today’s multi-channel digital audio connections.
STRUCTURE OF TORAY OPTICAL FIBER
AND LIGHT TRANSMISSION SCHEME
VERY LOW JITTER
Jitter is the undesirable deviation from the true periodicity of a assumed periodic signal in electronics and telecommunications, usually in relation to a reference clock source. A cable with very low vibration
