In recent years the interest in optical multiple-input multiple-output (MIMO) transmission has increased significantly. Focus of this work is the development of a time domain model of optical MIMO channels using modal diversity. Next to modal and chromatic dispersion, modal crosstalk caused by mode combiner, splitter, splices and also modal coupling within the transmitting fiber can be taken into account. The simulated MIMO impulse responses are validated by practical measurements. The channel measurements confirm the accuracy of the proposed time domain model.
