The HD video transmission specification based on coaxial cable converts HD video into optical signal, which is transmitted to the back end through fiber, and then transmitted to the back end through fiber.After the signal is transmitted to the receiver, optical-to-electrical conversion is performed, and then PFM demodulation is performed to recover the video signal. Due to the PFM modulation technology, the transmission distance can reach 20Km or more.By using CWDM technology, it is also possible to realize bidirectional transmission of image and data signals on one fiber to meet the actual needs of monitoring engineering. The TVI/CVI/AHD video converter should be working with the front TVI/CVI/AHD camera, TVI/CVI/AHD ball machine, and the back TVI/CVI/AHD video recorder.
TVI/CVI/AHD Fiber Video Converter are widely used in urban traffic monitoring systems, public security organs, safe city monitoring systems, highway security, toll systems, buildings, campus monitoring networks, industrial monitoring (airports, chemicals, steel, oil, railways, water conservancy , mines, etc.), military surveillance (warehouse, border defense, guard, defense, etc.) power oil field, television station program transmission system stadium (live video, audio transmission)
