The Performance Graphite Optical cable offers superior sound quality when connecting DACs, TVs, CD players, and Blu-ray™ players to amplifiers or receivers. It uses acrylic glass polymethylmethacrylate (PMMA) optical fibers for the comfortable transfer of high-capacity signals required by today's multi-channel digital sounds. The cable has been optimized for 'very low jitter' design to reduce digital errors, providing a clearer transmission of audio data.
