Description
Simultaneous Two-Way Stereo Transmission
The HL-101A Bidirectional 3.5mm Stereo Audio Fiber Extender is a professional-grade fiber optic transport system engineered specifically for concurrent, two-way audio signaling . It supports 1 channel of stereo unbalanced analog audio traveling in both directions simultaneously over long distances with zero signal degradation . Designed with a stereo single-ended input configuration, the device features standard 3.5mm stereo jacks for quick and clean physical connectivity . This bidirectional infrastructure makes it an excellent option for two-way remote multimedia education, video conferencing, live feedback monitoring for remote broadcasts, and commercial digital signage requiring a return audio path .
Advanced FPGA Digital Processing and High Fidelity
At the technical core of the HL-101A Bidirectional 3.5mm Stereo Audio Fiber Extender is a high-integration FPGA digital core used for precise encoding, decoding, and dual-end clock recovery . This processing architecture completely eliminates jitter, maintaining high linearity, a wide dynamic range, and exceptionally low distortion across a measurement bandwidth of 10Hz to 20KHz . Delivering professional digital processing, the device provides up to 24-bit resolution serial output and maintains native compatibility with I2S bus and MSB formats . It features versatile performance capabilities, supporting a 48 kHz basic sampling rate alongside a 96 kHz high-rate audio mode .
Universal Fiber Optimization and Plug-and-Play
Setup Engineered for highly flexible field deployment, the HL-101A Bidirectional 3.5mm Stereo Audio Fiber Extender features universal fiber compatibility, interfacing seamlessly with both single-mode and multi-mode optical networks . The system achieves an un-relayed transmission distance of up to 1KM over multi-mode fiber and a standard distance of 20KM over single-mode configurations, with structural customization available up to 100KM . This true hardware-based solution requires zero configuration or software installation . Built on a scalable architecture capable of supporting 1 to 32 channels, the portable desktop units are used in pairs and include integrated LED status indicators for real-time monitoring of power, fiber link status, and audio activity .
