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.
Core features
1. Transmission principle
Optical signal transmission: Digital signals are transmitted through laser/LED light pulses in the core of the optical fiber, completely avoiding electromagnetic interference.
Fully digital: Directly transmit uncompressed PCM encoding or multi-channel compressed audio.
2. Physical structure
Fiber core material: mostly plastic optical fiber or high-purity glass fiber.
3. Signal compatibility
Supported formats: Stereo PCM, multi-channel compressed audio
Typical application scenarios
1. Home theater: Connect TV, Blu-ray player, SoundBar to AV amplifier.
2. Game console: PlayStation/Xbox audio output to the sound system.
3. Professional equipment: Optical fiber interconnection of digital mixer and ADAT multi-track recording equipment.
