| Abstract | ||
| The polarization mode dispersion phenomena in the optical system causes shift of the center of the propagated pulse, pulse broadening, and changing the output state of polarization relying on random polarization mode dispersion vector and the input state of polarization. While, the polarization dependent loss phenomena causes a change of the power value relying on random polarization dependent loss vector and the input state of polarization. In this paper, an alternative model to combine the two phenomenon has been proposed, also an alternative formula of the output power that is linked to the input state of polarization and orientations of the random vectors of these two phenomenon is presented. The study showed that the output power fluctuates at limits ± 20% and pulse center shifts at limits ± 3ps for input normalized Gaussian pulse with initial width 5ps . Also, the study presented that the output SOP changes randomly due to these phenomenon. | ||
