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.
Product Features
1. Strong anti-interference ability
Principle advantage: Optical signal transmission does not rely on electrical signals and is completely free of electromagnetic interference.
Application value: It can ensure pure sound quality without noise, especially suitable for scenes with extremely high signal-to-noise ratio requirements such as recording studios and stage performances, avoiding the background noise problem caused by electromagnetic interference of traditional cables.
2. Fast transmission speed and extremely low delay
Light speed transmission: The speed of optical signals is close to 3×10⁸m/s, and the signal delay is negligible, which is much lower than the electrical signal transmission delay of traditional cables.
Applicable scenarios: Scenes with high real-time requirements avoid sound and picture asynchrony or lag in playing feel caused by delay.
3. Small size, light weight and long life
Physical characteristics: The cable is thinner than the same specification audio cable as a whole, which is convenient for concealed wiring; it has no metal material, is light and resistant to bending.
Durability: The optical fiber material is resistant to oxidation and corrosion, and is not affected by moisture or temperature changes. The service life can reach more than 10 years, far exceeding traditional copper wires.
4. Support high-specification audio transmission
Digital signal compatibility:
Support lossless audio transmission with high sampling rate and high bit depth, meeting Hi-Res audio standards.
Can transmit multi-channel surround sound signals, adapt to 5.1/7.1 channel systems of home theaters.
Interface type adaptation: Through TOSLINK, AES/EBU, HDMI optical fiber and other interfaces, compatible with consumer and professional devices.
