Multimode fibers (MMF) are high-capacity channels and are promising to transmit spatially distributed information, such as an image. However, continuous transmission of randomly distributed information at a high-spatial density is still a challenge. Here, a high-spatial-density information transmission framework employing deep learning for MMFs is proposed. A proof-of-concept experimental system is presented to demonstrate up to 400-channel simultaneous data transmission with accuracy close to 100% over MMFs of different types, diameters, and lengths. A scalable semi-supervised learning model is proposed to adapt the convolutional neural network to the time-varying MMF information channels in real-time to overcome the instabilities in the lab environment. The preliminary results suggest that deep learning has the potential to maximize the use of the spatial dimension of MMFs for data transmission.
