4 Channel RCA Audio Fiber Optical Extender Unidirectional Analog Audio Extender

  The 4-channel unidirectional RCA audio fiber optic extender converts four analog RCA audio signals into optical signals for long-distance transmission over fiber. Ideal for professional audio systems, this device ensures minimal signal loss and EMI/RFI-free transmission, delivering high-fidelity audio across distances up to 20 km (single-mode fiber) or 300 m (multi-mode fiber).

  Designed for broadcast studios, conference rooms, home theaters, and live sound systems, this extender supports stereo audio (left/right channels) on all four inputs. The plug-and-play design eliminates software configuration, while durable industrial-grade housing provides reliable operation in demanding environments.
