Serial transmission of image data through an optical fiber is inefficient in the utilization of the channel capacity of the fiber. Parallel image-transmission techniques, on the other hand, generally limit the transmission length to a few meters. A novel approach is introduced with which two-dimensional images can be efficiently transmitted through a single fiber at high speed. With this approach, images with space-bandwidth products greater than 2000 x 2000 can potentially be transmitted at a rate as high as 40 GHz.
