This premium cable features a full-sized Toslink connector on each end, with metal connector heads. The metal jacket helps protect the cable from nicks, cuts, and kinks, which could cause damage to the internal optical fiber. Being an optical signal, Toslink is immune to problems that can plague electrical signals, such as crosstalk, magnetic interference, or radio frequency interference. Its contacts are 24k gold plated, and the connectors are full metal, matt-chromed. All cables of the HomeCinema series are produced with 99.99% oxygen free copper (OFC), and are triple shielded to guarantee optimal audiovisual performance.
