QED’S MULTIPLE AWARD WINNING TOSLINK OPTICAL DIGITAL AUDIO CABLEThe Award-winning ‘Performance Graffiti’ Optical cable lets you experience superior sound quality when connecting DACs, TVs, CD players and Blu-ray TM players to amplifiers or receivers. Performance Optical uses a polymethyl methacrylate (PMMA) acrylic glass optical fiber to comfortably transmit the high-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. At QED, we are so confident in the performance of our product that we offer a lifetime warranty. |

FEATURES AND BENEFITS
POLYMETHYL METHACRYLATE (PMMA) ACRYLIC GLASS OPTICAL FIBERThis 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 DESIGNAt 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 LOSSVery low loss <0.15dB attenuation per meter FEATURESPlastic Optical Fiber (POF) core made of acrylic glass Graduated refractive index Fluorinated Polymer Coating Material 24K gold plated Toslink connectors Precision engineered plug integrated grip Attenuation ‹0.15dB / m (650 nm) Numeric Aperture 0.5 Minimum bending radius 9 mm QED Lifetime Warranty |
