Abstract
Multiple input, multiple output (MIMO) communication systems and a method using multimode media are provided. A MIMO communication system includes an array of emitters that receives a data signal and outputs a plurality of signals (e.g., modulated light, or other signal types) representative of the data signal, a multimode medium (e.g., a multimode fiber, a fiber bundle, a bundle of cables) that receives the plurality of signals from the array of emitters and carries the plurality of signals in a plurality of modes, and an array of detectors that receives the plurality of signals carried by the multimode medium and outputs the data signal. The system can include a demultiplexer that demultiplexes a single high-speed data stream into the array of emitters as the data signal. The system can also include a multiplexer that multiplexes the data signal from the array of detectors back into the single high-speed data stream.
