Answer:
Yes it does. I have quoted the section in our documentation which describes how we model PMD for the Optical Fiber component. You can find this information by right clicking on the Optical Fiber Component, choosing Component Properties and then clicking on Help.
The “coarse-step method” [11] is used to simulate the PMD effects in the “Stochastic” mode. The fiber is represented by a concatenation of trunks and the propagation of light in each trunk is simulated by the split-step Fourier method described in the previous section. The lengths of the trunks are random numbers with a Gaussian distribution [12].
