[Machine Translation] SUPRA ZAC is a high quality optical cable supporting 24bit/192kHz. ZAC" is named after the Zero Attenuation Concept. Using SUPRA's technology and know-how cultivated through the production of various audio cables, the resin fiber is polished into a special curved shape. The result is a cable with excellent transmission characteristics and low jitter, equivalent to glass fiber, in addition to the strength and elasticity inherent in resin fiber, enabling users to enjoy high resolution sound quality with excellent S/N ratio. The greatest advantage of optical transmission is that there is no noise radiation from the cable, and the optical cable can completely block noise from the outside. This optical cable is ideal for portable players that are susceptible to external noise.
