Multiple SDI to Fiber: Seamless Multi-Channel Video Transmission

The Multiple SDI to Fiber solution is revolutionized by the PTZ‑4M Portable 8K Multi-Service SDI Over Fiber Extender. This device allows broadcasters to transmit up to 5 channels of 12G-SDI, compatible with 6G, 3G, HD, SD-SDI, and DVB-ASI. Four forward channels and one reverse channel provide simultaneous video delivery and return signals, making it perfect for live productions where low latency and high signal integrity are essential. By converting multiple SDI signals into a single optical fiber, PTZ‑4M reduces cabling complexity while delivering pristine, high-definition video quality.

Integrated Control and Connectivity: Streamline Your Workflow

PTZ‑4M goes beyond simple SDI transmission. It integrates bidirectional RS422 control, Ethernet (10/100/1000M), GPI/O triggers, and synchronization signals over the same fiber. This allows operators to remotely control PTZ cameras, robotic dollies, or gimbal systems without extra cables. The intuitive LCD display shows optical power, video status, and device ID in real-time, giving users full visibility and control in fast-paced field operations.

Portable and Rugged Design for Field Production

Designed for on-the-go use, PTZ‑4M’s half-rack, lightweight design allows easy deployment in challenging environments. Low power consumption (<7W) combined with AC/DC/V-mount battery options enables over 8 hours of continuous operation in outdoor broadcasts or mobile production setups. Its silent, sealed enclosure ensures reliable performance in dusty, windy, or noise-sensitive locations.

Reliable Long-Distance Transmission: Maintain Signal Integrity

With support for hot-swappable modules and robust fiber connections, PTZ‑4M achieves up to 10 km of optical transmission without signal degradation. Its high reliability and flexible power options allow broadcasters to confidently deploy it in studios, broadcast vehicles, or remote locations. Whether for live concerts, sports events, or remote ENG productions, PTZ‑4M ensures smooth, high-quality video delivery.

Why Multiple SDI to Fiber Solutions Are Essential

As the broadcast industry moves to 4K and 8K resolutions, traditional coaxial SDI transmission becomes bulky and costly over long distances. Multiple SDI to Fiber solutions consolidate multiple SDI channels into a single optical fiber, reducing infrastructure complexity and improving flexibility. PTZ‑4M exemplifies this approach, offering a compact, integrated solution that optimizes multi-camera workflows while maintaining maximum video fidelity.
