1 product introduction

The uncompressed VGA high-definition optical terminal developed and manufactured by Beijing Huachuang TV can be transmitted over a long distance through a single-core optical fiber. The standard VGA video, audio, RS232 data, PS2 keyboard and mouse, infrared and other business signals are available. The design emphasizes reliability and excellent resolution image performance. Full digital and uncompressed technology is used to transmit VGA video images with resolution up to 1920X1200 @60Hz (WUXGA) or 1080p @60Hz (HDTV) perfectly without losing frames and delay. The product is equipped with LED signal indicator to display the state of power, video and optical signals. VGA high-definition optical terminal is widely used in military command and control, public security command and control, traffic police traffic management, energy and power supply industry, government departments, medical system, commercial display, multimedia function hall, public utilities and many other fields.

2 characteristics:

Transmission of 1 channel VGA HD video, 1 channel bidirectional stereo audio, 1 channel RS232 data bidirectional, 1 channel bidirectional PS2 mouse keyboard transmission, 1 channel bidirectional infrared transmission;

Digital non compression technology, no damage, no delay, no fault time greater than 100 thousand hours.

All components are of high quality, SMT surface mounting technology, VLSI design with FPGA, industrial standard, circuit stability and reliability.

The power supply and other parameters indicate that LED can monitor the system status.

Supports the highest resolution up to 1920 * 1080 @60Hz, 1920 * 1200 @60Hz, plug and play, without adjusting to achieve high quality image output;

The optical fiber interface is the standard FC, the standard transmission distance 20KM, optional 40KM, 60KM, 80KM, 100KM;

Using CWDM technology, single fiber can transmit 16 channels of VGA video, audio, data and other functions.

Products provide independent, 1U rack type, 4U rack type; 4U rack type with dual power supply, support hot plug, no debugging and installation;
