QED Performance OPTICAL Graphite Digital Audio Cable

QED Performance OPTICAL Graphite Digital Audio Cable allows you to experience superior sound quality when connecting DAC’s, TV’s, CD players and Blu-ray TM players to amplifiers or receivers.

Performance Toslink Optical uses a polymethyl methacrylate (PMMA) acrylic glass optical fibre to comfortably transmit the higher bandwidth signals demanded by today’s multi-channel digital audio links. The cable is optimised for a ‘very low jitter’ design to reduce digital errors, making for a cleaner audio data transmission.

Very Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying very low jitter has been measured at
typically 50ps.
