“…We considered a laser linewidth of 100 kHz for both transmitter and receiver sides. The dynamic response of the PMD is simulated using dynamic wave plate model as proposed in [17]. This model generates a continuous PMD variation and correlation between adjacent time samples.…”

We report an adaptive weighted channel equalizer (AWCE) for orthogonal frequency division multiplexing (OFDM) and study its performance for long-haul coherent optical OFDM (CO-OFDM) transmission systems. This equalizer updates the equalization parameters on a symbol-by-symbol basis thus can track slight drifts of the optical channel. This is suitable to combat polarization mode dispersion (PMD) degradation while increasing the periodicity of pilot symbols which can be translated into a significant overhead reduction. Furthermore, AWCE can increase the precision of RF-pilot enabled phase noise estimation in the presence of noise, using data-aided phase noise estimation. Simulation results corroborate the capability of AWCE in both overhead reduction and improving the quality of the phase noise compensation (PNC).

“…Temperature-induced slow polarization variations as well as fast, random fluctuations induced by mechanical vibrations occur along the fiber link. Consequently a complete characterization of PMD compensation techniques should incorporate a reasonable model of the dynamic behavior for the fiber channel, which includes the effects of PCs, control algorithms, and the speed of the PMDC [23]. The first task in designing an optical PMDC is to define the number of stages, which should be sufficient to achieve the target PMD tolerance.…”

This paper details and describes optical polarization mode dispersion compensators (PMDCsnature of PMD makes it a difficult problem. PMD not only varies randomly over the wavelength, which gives rise to higher order PMD, but drifts randomly with time as well due to environmental changes such as temperature variations and mechanical vibrations along the fiber.To reduce PMD impairments, various PMD mitigation techniques have been proposed and demonstrated [2]. In general, PMD mitigation techniques can be divided into three main approaches:

“…By now many polarization state transformer use simple two waveplates configuration to transform the state of polarization of light, which can transform any arbitrary linear state of polarization (SOP) to an arbitrary SOP [1,2]. Therefore, it is necessary to investigate its accuracy of polarization transform.…”
