Plastic optical fiber cable for car audio and video signal transmission control is a kind of optical fiber made of high molecular polymer (such as PMMA, polycarbonate), specially designed for the transmission of audio, video and control signals in the car environment.
Key features
Material and structure
Fiber core: high refractive index polymer (such as PMMA).
Clad: low refractive index material, forming a fully reflective transmission path.
Diameter: usually 0.5mm~1mm, thicker than glass fiber, easy to install in the car.
Transmission performance
Bandwidth: up to hundreds of MHz, meeting high-definition audio/video requirements (such as the MOST150 standard supports 150Mbps).
Wavelength: commonly used 650nm (red light) or 850nm (near infrared).
Automotive adaptation design
Vibration resistance/temperature resistance: adapt to the vehicle environment of -40°C~85°C.
Lightweight: reduce the weight of the wiring harness and optimize the wiring space.
EMI immunity: not affected by electromagnetic interference from engines, motors, etc.
Connector type
Standard MOST interface (such as MOST ring network).
Customized plug (such as TOSLINK variant) to ensure fast plugging and unplugging and sealing.
Typical application scenarios
High-end in-car entertainment system: surround sound, rear audio and video transmission.
In-car network: MOST bus connects host, amplifier, display and other nodes.
ADAS auxiliary system: partial sensor signal transmission.
