Fiber optic video converter which assists wired transmission is a kind of equipment converting signals mode between optical and electronic. Fiber optic video converter involves analog type and digital type:
Analog Fiber-optic-video-converter
Analog fiber-optic-video-converter which adopts PFM skill for image transmitting in real-time is very popular today. Transmitting-terminal modulates video signal with PFM skill, converts electronic signal into optic signal. After receiving-terminal getting optic signal, optic signal is converted back into electronic signal and is modulated by PFM skill. Finally, video signal can be displayed on monitor directly.
Digital Fiber-optic-video-converter
Compared with traditional analog fiber-optic-video-converter, digital fiber-optic-video-converter has many advantages in many aspects, so the digitalization of digital fiber-optic-video-converter is the inevitable trend. There are two skill modes for digital image fiber-optic-video-converter: the one is MPEG II compression fiber-optic-video-converter, the other is non-compression fiber-optic-video-converter. Digital image fiber-optic-video-converter usually adopts MPEG II compression skill which can compress image into N×2Mbps stream, then transmitted by standard telecommunication interface or by cable directly. Non-compression fiber-optic-video-converter usually converts signal between analog and digital, then reconnects with audio signal, finally all signal is transmitted by cable.
