Product Overview
The 3G‑SDI video optical transceiver is independently developed by our company and boasts proprietary intellectual property. Drawing on the strengths of comparable products both domestically and internationally, and aligned with actual market needs, it leverages a single‑fiber link to transmit four forward‑direction 3G‑SDI video signals, enabling lossless, uncompressed, high‑quality signal extension up to 20 kilometers.
The 3G‑SDI video optical transceiver employs imported components for both its optical module and core circuitry, ensuring stable performance. Featuring an integrated‑circuit design, it is compact and easy to install and commission, requiring no maintenance. Moreover, by utilizing optical fiber as the transmission medium, it delivers exceptional performance, with superior resistance to high temperatures and extreme cold, while effectively mitigating interference from strong electromagnetic radiation, lightning surges, and power‑line spikes, thereby significantly enhancing its stability and reliability.
Product Features
1. Complies with EN 50083‑9, SMPTE 259M(C), SMPTE 292M, and SMPTE 424M standards.
2. Input with cable equalization, capable of compensating for cable transmission losses.
3. It features a clock recovery circuit that reduces signal jitter during output, enabling effective handling of distorted signals.
4. The input/output cable can transmit over distances of up to 80 m (using BELDEN 8281 cable).
5. The optical port supports multimode or single-mode, and can be configured for single-fiber or dual-fiber operation.
6. Supports CWDM technology for multi-channel signal transmission, high capacity, and easy upgrades.
7. Employs all-digital processing technology, delivering crisp images with no color phase distortion.
8. Plug and play—no configuration required.
