The utility model provides a kind of KVM seat system based on fiber optic communication, including distributed input node, KVM switch controller and distributed output node;Distributed input node includes the 1st single-chip microcontroller, digital video input interface . The invention discloses a KVM (keyboard video mouse) seat management monitoring system based on optical fiber communication, which comprises a plurality of KVM seat input units, a KVM seat output unit, an image splicing processing unit, an optical fiber network information exchanger, a control. For the AV OVER IP IP Based KVM system, We have 2K60,4K60,Dual-Engine distributed system and SDVoE 4:4:4 Lossless distributed system optional based on different projects requirements. 1) Distributed architecture design, decentralized architecture, can expand any number of nodes without server and. Distribution KVM seat collaboration is to quickly and easily achieve information-sharing and address issues between seats. Matrox KVM extenders can extend signals—such as keyboard, mouse, audio, video, RS232, and USB—over fiber, copper, LAN, or private WAN. With best-in-class. System Overview: Node size 76 ASTEROID + splicing processor, in the realization of a three-area network completely isolated under the premise, but also through the tablet and control PC to achieve the signal on the screen call. “ASTEROID” network distributed seat can simultaneously access different.
