Product Description

This product listing features 4 different fiber optic extender models with HDMI, DVI, VGA, and SDI interfaces respectively, all available for purchase under one convenient link. Simply select your required interface type from the dropdown menu above to get the perfect solution for your specific AV transmission needs.
Each model in this series is a professional-grade audio/video transmission solution designed for long-distance signal distribution over fiber optic cabling. They deliver pristine, uncompressed high-definition video and audio signals with zero latency, making them ideal for mission-critical applications where signal integrity and reliability are paramount.
Enhanced with advanced features: Built-in USB KVM support allows you to remotely control connected computers and devices using a keyboard and mouse at the display end. Independent audio transmission ensures clear stereo sound even for video interfaces that don't natively carry audio. The convenient local loop-out function provides a real-time video feed at the transmitter end, greatly simplifying installation, debugging and on-site monitoring.
Utilizing advanced fiber optic technology, all our extenders eliminate electromagnetic interference (EMI), radio frequency interference (RFI), and ground loop issues commonly associated with copper cable transmissions. They support transmission distances up to 20 kilometers over single-mode fiber, enabling seamless connectivity between video sources and displays across large facilities, campuses, or multi-building environments.
The plug-and-play design requires no software configuration or complex setup, making installation quick and hassle-free. The industrial-grade metal enclosure with ESD protection ensures stable 24/7 continuous operation in demanding environments.
