Product Overview
The GQ6004ZA‑R‑T/R optical audio transceiver employs all‑digital fiber‑optic transmission. During transmission, the analog audio signal is converted to a digital format via A/D conversion and then carried digitally. It enables real‑time, lossless, high‑quality long‑distance audio transmission over a single‑fiber link, with a maximum unrepeated transmission distance of up to 100 km. The audio interface features 24‑bit AD/DA conversion and 128 kHz sampling, delivering broadcast‑grade transmission quality. This optical audio transceiver is widely applicable across numerous sectors, including videoconferencing, public security, fire services, the military, meteorology, railways, and aviation.
Product Features
1. Supports four-channel unbalanced analog audio forward transmission.
2. The optical port supports multimode or single-mode, single-fiber or dual-fiber, and is available with FC, SC, ST, or LC connectors.
3. Standard broadcast‑grade analog balanced audio, compatible with I2S bus and MSB format, with serial output up to 24 bits.
4. Stereo single-ended input configuration, with high linearity, wide dynamic range, and low distortion.
5. Employing FPGA, digital encoding/decoding, and clock recovery technologies, it offers high integration and excellent stability.
6. LED status indicator, enabling monitoring of the device’s operating condition.
7. Plug and play—no configuration required.
