The Premium optical cable is characterized by its high-quality nylon fiber and precisely-fitting TOSLINK connector. It is used to connect digital audio sources such as CD, DVD, Blu-ray players and games consoles to AV receivers and similar devices. Signal transmission is of exceptional quality, with the Premium optical cable transmitting digital audio signals with high clarity and precision. This ensures excellent audio quality, plus minimal signal loss and interference. The virtually interference-free transmission brings tremendous advantages. Optical cables are resistant to electromagnetic interference (EMI) and radio frequency interference (RFI) because they use light instead of electrical current. This enables reliable and virtually interference-free signal transmission, even in environments containing many electronic devices.
