Audio optical cable, also known as fiber optic audio cable or TOSLINK cable (Toshiba Link), is a special connection cable that uses optical fiber (optical fiber) to transmit digital audio signals. It uses light pulses (rather than electrical signals) to achieve lossless audio data transmission between devices and is widely used in home theaters, Hi-Fi audio systems and professional audio equipment.

Optical fiber cable is a special optical cable used to transmit audio signals. It uses optical signals as carriers to transmit audio data. It has the advantages of strong anti-interference ability, long transmission distance, and low sound quality loss. It is widely used in professional audio fields, home theater systems and high-end audio equipment.Core principle: Optical fibers such as glass or plastic are used as transmission media to transmit audio signals through the principle of total reflection of light. The electrical signal needs to be converted into an optical signal through an optical transmitter, and then restored to an electrical signal by an optical receiver after being transmitted through the optical cable, and finally the audio is output.
