“…And also, since the pulse positions of the two pulses are different in the Z-axis, the nonlinear effect from the Y-axis pulse cannot affect the whole value to the X-axis pulse. We have found that a similar explanation was reported before [8].…”

We investigate the effect of polarization-mode dispersion (PMD) on the optimum dispersion compensation (ODC) monitoring and nonlinear penalty in optical transmission systems. We report that PMD may reduce the fiber nonlinearity. We also report that the monitoring error of the clock-based ODC monitoring technique decreases after the first-order PMD compensation. A simple explanation of this phenomenon is shown.

“…One example of this effect is that a nonlinearly induced pulse chirp can interact with higher-order PMD to lead to additional pulse spreading beyond the spreading that is induced by first-order PMD or can induce pulse compression. This effect was predicted by Ibragimov et al [27] and was recently observed by Möller et al [28]. A second example of this effect is that nonlinear polarization rotation induced by wavelength division multiplexed interactions can lead to fast variations of the polarization states that impede the ability of standard PMD compensators to mitigate signal degradation that is due to PMD.…”

There has been a flood of recent work on polarization effects in optical fibers, most of it focused on polarization mode dispersion (PMD). There are good, practical reasons for this recent interest. As the data rate per channel increases, PMD becomes an increas-ingly important limitation in communication systems. However, my own interest in polarization issues was, at least originally, focused on more fundamental questions. Since nearly all the contributions in this volume focus on the more immediate practical issues that are a consequence of polarization effects, it seemed useful to me to focus this contribution on more fundamental issues. The nice thing about fundamental issues is that even though they attract less attention than immediate practical issues, they typically stay relevant longer and can impact practical issues 10-20 years in the future.Throughout the 1970s, a considerable body of work established the basic polarization properties of optical fibers. Much of this work was summarized by Kaminow in 1981 [1]. It was found that the birefringence ∆n/n is in the range 10 −4 -10 −9 , with communication fibers in the range 10 −6 -10 −7 . It was found that the intrinsic

“…In the absence of residual birefringence, randomness comes only from the bit pattern. The SOP of pump and probe variance can be obtained by taking the inverse Fourier transform of equation (8) along the fiber link length L, , we assume that the effects of dispersion and nonlinearities do not significantly change the pulse shape of the pump channel along the fiber and analytically solving(1), we then obtain,…”

“…It has an important impact on the performance of high-speed wavelength division multiplexing (WDM) in optical fiber communication systems [1]. In the last few years, many research works have been carried out on the interaction among fiber nonlinearity, polarization variation and polarization mode dispersion (PMD) [2][3][4][5][6][7][8]. Physically, PMD has its origin in the birefringence that is present in any optical fiber.…”

Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of the channels through nonlinear polarization rotation and induces nonlinear time dependent phase shift for polarization components that leads to amplitude modulation of the propagating waves in a wavelength division multiplexing (WDM) system. Due to the presence of birefringence, the angle between the SOP changes randomly and as a result polarization mode dispersion (PMD) causes XPM modulation amplitude fluctuation random in the perturbed channel. In this paper we analytically determine the probability density function of the random angle between the SOP of pump and probe, and evaluate the impact of polarization mode dispersion on XPM in terms of bit error rate, channel spacing etc for a two channel intensity modulation-direct detection WDM system at 10 Gb/s. It is found that the XPM induced crosstalk is polarization independent for channel spacing greater than 3 nm or PMD coefficient larger than 2 ps/√km. We also investigate the dependence of SOP variance on PMD coefficient and channel spacing.
