Description
Professional Two-Way Audio Integration
The HL-202RA is a professional-grade fiber optic transceiver system engineered for the simultaneous bidirectional transmission of 2-channel unbalanced analog audio. This hardware-based solution allows high-fidelity audio signals to be sent and received over a single fiber link, making it an ideal choice for intercoms, remote broadcasting, and two-way monitoring systems. By utilizing fiber optic technology, the system provides complete electrical isolation, which effectively eliminates common audio issues such as ground loops and hum.
Advanced 2-Channel Bidirectional RCA Audio Fiber Extender
As a dedicated 2-Channel Bidirectional RCA Audio Fiber Extender, the HL-202RA supports a stereo single-ended input configuration via standard RCA interfaces. The device employs FPGA-based digital coding and decoding with advanced clock recovery to maintain high linearity and a wide dynamic range. It delivers professional audio quality with a frequency response of 10 Hz to 20 kHz and supports sampling rates of 48 kHz in basic mode or up to 96 kHz in high rate mode.
Reliable Long-Distance Transmission
Designed for versatile deployment, this extender is compatible with both multi-mode fiber for distances up to 1 KM and single-mode fiber for standard distances of 20 KM. The system features dedicated LED monitoring for power, fiber link, and operational status to ensure consistent performance in the field. Because the units are entirely plug-and-play, they require no software setup or IP configuration, though they must be used in matched pairs to facilitate a proper fiber link handshake.
