Mode Partition Noise and Modal-Chromatic Dispersion Interaction Effects on Random Jitter

The generation and accumulation of random jitter (RJ) in channels using multimode fibers (MMF) and vertical cavity surface emitting lasers (VCSEL) is investigated. A novel theoretical model that accommodates mode partition noise (MPN) and modal-chromatic dispersion interaction (MCDI) for the length dependence of RJ in VCSEL-MMF channels is developed. The proposed model requires a few channel parameters such as length, MPN coefficient, spectral width of the source, and a new parameter for describing the modal-chromatic interaction. Simulation predictions are verified by experiments.
