The F-2V4A is a video to fiber multiplexer that carries two channels of composite video and four channels of audio over a single fiber. Our unit uses higher quality 10-bit digital transmission techniques which eliminates signal static and blur. The unit is for optical transport of 2 baseband video and 4-audio over one single mode or multimode fiber. The video to 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. 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.
