“…Modal dispersion between non-degenerate groups of modes leads to relative shifting of bit sequences in modal channels and mitigate its interaction. Similar effect was described for inter-channel nonlinear interaction via cross-phase modulation (XPM) for single-mode WDM-systems, when chromatic dispersion leads to «walk-off effect» for bit sequences of different spectral channels [17].…”

In this paper we consider nonlinear impairments of mode division multiplexed signals with QAM modulation in optical fibers with linear mode coupling of spatial modes. We simulate simultaneous propagation of fundamental mode and two first-order vortex modes in standard single mode fiber at 850 nm and propagation of fundamental mode and first-and second-order vortices in step-index fiber with enlarged core at 1550 nm. Simulation results shows that in strong coupling regime linear coupling lead to sufficient increasing of nonlinear impairments, but QAM-modulated signal is more robust to this effect than OOK modulated signal.

“…зависимости поляризации сиг-нала на одной длине волны от поляризации сигнала на другой длине волны. При этом изменение поляризации зависит от амплитуды влияющих сигналов, то есть не-посредственно от последовательности передаваемых бит при ООК-передаче [6]. Описанный эффект приво-дит к деполяризации сигналов.…”

We consider interaction of polarization-mode dispersion (PMD), Kerr-nonlinearities and chromatic dispersion and its effect on the quality of WDM-transmission in a fiber link. We simulate the propagation of RZ- and NRZ-coded signals in a multispan link with optical amplification and chromatic dispersion compensation. For some fiber realizations signal impairments reduction occurs in the case of PMD and nonlinearities interaction as compared to the case of nonlinear transmission with no PMD. This signal enhancement is related to the pulse compression and this phenomenon is determined by the frequency dependence of PMD.

“…These studies were carried out [7][8][9] to evaluate the bit error rate (BER) performance of OCDMA considering only the effect of group velocity dispersion (GVD). It is well known that polarization mode dispersion (PMD) severely degrades the BER performance of optical fiber communication at high bit rate [10][11][12][13][14][15][16][17][18][19] due to differential group delay between two principal states of polarization which causes spreading and overlapping of bits. In case of OCDMA system, it is believed that the BER performance will degrade more by the PMD due to transmission of short duration chip.…”

In this paper, impact of polarization mode dispersion (PMD) on the bit error rate (BER) performance of direct sequence optical code division multiple access with in-line optical amplifiers is analytically investigated. Intensity modulation direct detection technique is employed in optical correlator receiver. Optical orthogonal codes are used as address sequence. The system BER performance is determined in presence of PMD and different noises induced from receiver, optical amplifiers, and multiple access interference. The power penalty suffered by the system is evaluated at BER of 10^-9. It is found that the BER performance of the proposed system degraded more at high chip rate, chirp parameter and long fiber length due to the effect of PMD. Further, the BER performance of the proposed system is studied in presence of PMD compensation with frequency advanced higher order PMD vectors. The results demonstrate that the system BER performance is improved significantly for a particular fiber length and third-order PMD compensation technique shows better performance compared to first-, and second-order compensations.
