HL-202A Bidirec onal 3.5mm Stereo Audio Fiber Extender

Simultaneous Dual-Channel Bidirectional Stereo Transport The HL-202A Bidirectional 3.5mm Stereo Audio Fiber Extender is a professional-grade fiber optic transport system engineered for high-performance, two-way audio networking . The device supports two independent stereo pairs—totaling four mono channels—traveling in both directions simultaneously across long distances with exceptional signal stability . Featuring industry-standard 3.5mm stereo jacks mapped to an unbalanced, stereo single-ended input configuration, it provides quick and clean physical connectivity . This dual-channel bidirectional infrastructure makes it highly effective for simultaneous two-way remote multimedia education, dual-link video conferencing, and live multi-channel feedback monitoring for remote broadcasts requiring an active return audio path . Advanced FPGA Digital Processing and High-Resolution Audio At the technical core of the HL-202A Bidirectional 3.5mm Stereo Audio Fiber Extender is a highly integrated FPGA digital core utilized for precise encoding, decoding, and dual-end clock recovery . This processing platform actively eliminates high-frequency jitter to ensure maximum timing stability across a comprehensive measurement bandwidth of 10Hz to 20KHz . Delivering studio-grade fidelity characterized by high linearity, a wide dynamic range, and an exceptionally low-distortion sine wave output, the device generates up to 24-bit resolution serial streams . To accommodate advanced studio workflows, it natively supports professional I2S bus and MSB format compatibilities while offering versatile operational parameters that include a 48 kHz basic sampling rate and a 96 kHz high-rate processing mode . Universal Fiber Optimization and Zero-Configuration Setup The HL-202A Bidirectional 3.5mm Stereo Audio Fiber Extender delivers universal optical flexibility, operating seamlessly across both single-mode and multi-mode fiber infrastructures . It achieves an un-relayed transmission distance of up to 1 KM over multi-mode configurations and a standard distance of 20 KM over single-mode networks, which can be custom-tailored to cover long-haul routes up to 100 KM via standard FC optical connectors . This true hardware-based solution requires zero configuration, software installation, or manual calibration . Built as portable desktop units deployed in dedicated transmitter and receiver pairs, the devices include integrated LED panel indicators for immediate, real-time monitoring of power, fiber link connectivity, and active audio status .
