Abstract
The multimode optical fiber maximum operational range is defined by the fiber bandwidth (related to the intermodal dispersion) rather than by the fiber attenuation. The relation among the modal bandwidth of the fiber, the launching condition and mode coupling is fairly complicated. Presented is a theoretical and experimental study on the modal bandwidth of the multimode fiber. Theory is based on the numerical solution of coupled mode diffusion equation that allows for the bandwidth calculation of the MM optical fiber. The results are backed by measurements. In the Telecommunications Institute, Warsaw, such measurements may be performed up to ~600 MHz with a set up based on the frequency response measurement. The MM fibers are excited via a single mode patchcord with mechanically adjusted offset from the center. The patchcords with various MFDs can be used.
