1. Adopting a closed-loop fiber optic KVM architecture, video, audio, and control signals can be collected and output controlled through a single fiber optic cable;

2. The input and output nodes adopt high-performance image processing chips, supporting YUV/RGB444 signal format input and output;

3. Fiber optic transmission processing technology that supports lossless non coding and decoding, with resolutions up to 3840x2160@30Hz , and backward compatibility, providing high-quality image transmission;

4. Supports dual fiber backup, and supports manual or automatic switching between links;

5. The node has ≥ 1 HDMI2.0 interface, ≥ 1 5pin Phoenix balanced audio interface, ≥ 2 fiber optic interfaces, ≥ 3 USB interfaces, and ≥ 1 Micro USB interface;

6. Seat OSD visualization operation, supporting signal preview, switching between signal list and preview, pushing to screen, pushing seats, crawling, and grouping permission seats. The seat can support single split screen, 4-split screen, and custom split screen methods;

7. Support USB 2.0 transparent transmission function, which can transfer files in both directions, ensuring the security and controllability of USB 2.0 transmission data;

8. Support rack mounted centralized power supply installation.
