The unit sending 4 individual baseband videos and 8 audio channels over a single fiber. Fiber optic video audio transmitter, digitizes video and audio and converts it to a digital uncompresed form. It sends modulated light signals to the fiber optic receiver where it is converted back to analog video and audio. We have many different standard and custom-built solutions for video to fiber transmission. Our video over fiber converters are ideal for multiplexing up to 32 composite video channels and 64 audio channels over a single fiber. We also build units for bi-directional transport of signals in over a single fiber. The F-4V8A is a video to fiber multiplexer that carries four channels of composite video and 8 channels of audio over a single fiber. Our unit uses higher quality 10-bit digital transmission techniques which eliminates signal static and blur. Our units are designed to work with standard single-mode or multimode optical fiber with fiber optic transmission distances of up to 120km when used with single-mode fiber.
