Description
Overview
GAOTek multiplexer over video/audio fiber optical to HD SDI converter is a video converter is HD uncompressed professional optical fiber equipment that HO-LINK solves single channel or multichannel 3G/HD-SDI AV, GbE, RS485 data long distance transmission problems. The 3G/HD-SDI converter products were first developed and used by customers in the broadcasting industry. It was applied to the TV station studio, the games for university students live broadcast, later extended to 1080P HD surveillance and it can be equipped with reverse control data, the rate is 1.485G (also called 1.5, corresponding to SMPTE-292 standard, support 720P) and 2.97G (also called 3G, corresponding to SMPTE-424 standard, support full HD 1080P) SDI converter adopts HD SDI dedicated VIDIO SFP optical module to ensure no flash screen or black screen during HD image transmission. It uses advanced uncompressed digital HD video and high-speed digital fiber transmission technology to convert 1.485 Gbps HD-SDI digital signals into fiber signals, which can be transmitted to fibers for 1 to 20 km and then restored to electrical signals. It is widely used in Radio and Television, video conferencing, medical teaching, security monitoring and other high-demand industries. It suitable for SDI video monitoring and long-distance video capture. The series of converter have stable performance, clear picture quality, high stability, and LED status indication which can visually observe the working state of the converter.
