Summary:
The F-SDI-3G-B-TX/RX stands out from competitors primarily due to its true broadcast-grade quality and use of pure hardware architecture. While many similar converters on the market rely on software-based processing, which can introduce latency or compatibility issues, this unit offers zero-compression, zero-delay transmission with superior signal integrity. Its full compliance with SMPTE standards (including 424M for 3G-SDI) ensures that it works seamlessly with professional video equipment, and its ability to handle pathological test patterns gives it an edge in environments where signal reliability is non-negotiable.
Another key advantage is its longer transmission range and versatility. Many competing SDI-to-fiber converters are limited to shorter distances or require dual fibers for bidirectional communication. The F-SDI-3G-B-TX/RX supports bidirectional video over a single fiber up to 20 kilometers without repeaters, reducing installation complexity and cost. It also supports CWDM (Coarse Wavelength Division Multiplexing), allowing for scalable multi-channel setups—something not typically available in entry-level or mid-range devices.
Additionally, its rugged industrial design and modular flexibility provide significant operational benefits over competing products. Combined with robust safety features, extreme temperature tolerance, and plug-and-play ease of use, the F-SDI-3G-B-TX/RX delivers a professional-grade solution that goes well beyond the capabilities of typical SDI fiber converters.
F-SDI-3G-B-TX/RX – Bi-Directional 3G-SDI over one fiber – 20 km
F-SDI-3G-B-TX/RX-40 – Bi-Directional 3G-SDI over one fiber – 40 km
F-SDI-3G-B-TX/RX-80 – Bi-Directional 3G-SDI over one fiber – 80 km
