SD-SDI / HD-SDI / 3G-SDI Digital Video Over Fiber Converter
SD-SDI / HD-SDI / 3G-SDI Digital Video Over Fiber Converter HD Video Transmission Video Audio Transmission Equipment AD-Net Selangor, Malaysia, Kuala Lumpur (KL), Petaling Jaya (PJ) Supplier, Suppliers, Supply, Supplies | Catacomm Corporation Sdn Bhd
In this video, let¡¯s make a quick setup of our SDI to Fiber converters with HD SDI camera and CCTV tester as remote video signal viewing device:


AD-net’s SDI SD / HD / 3G video digital optical converter adopts international advanced all-digital gigabit optical fiber transmission technology. These standards are used for transmission of uncompressed, unencrypted digital video signals (optionally including embedded Audio and/or Time Code) within television facilities; they can also be used for packetized data. And now – with AN-DVI fiber optic devices you can deliver those signals on large distances over the fiber optic cables.
HD SDI video signal can be transmitted through 1 single fiber with non-distortion, high-quality, long-distance transmission .This series of video to fiber converter has Stable performance, clear picture quality.,and high Stability with LED Status Indication on the body of device. the working status of devices can be visually observed.At the same time,the switch value,voltage,working status and other reverse useful signal information can be controlled by data RS485.This makes our devices more flexible when different customers’ request comes.
Possible applications for this product, to name few are:
Intelligent Traffic Monitoring System.
Security system
School networking
Industrial monitoring (Electricity,Chemistry,Steel,Oil,Railway & etc)
Military Monitoring (Warehouse,Border,Guards,etc)
TV programme transmission system.
Stadium (For LIVE HD video,audio transmission)
