TL;DR: In this paper, the authors decompose a fiber Jones matrix into amplitude and phase responses, which are then compensated for separately by cubic and higher-order phase compensation, respectively, for a 40Gbit/s non-return-to-zero signal with a differential group delay of 20 ps (rms).
Abstract: Polarization mode dispersion (PMD) compensation is addressed by decomposition of a fiber’s Jones matrix into amplitude and phase responses, which are then compensated for separately. Cubic and higher-order phase compensation substantially reduce the cumulative probability at a given system penalty over first-order PMD compensation, as demonstrated for a 40‐Gbit/s non-return-to-zero signal and a fiber PMD with a differential group delay of 20 ps (rms). Single-stage all-pass filters provide tunable compensation that is comparable to that obtained with a variable-delay line, and multistage all-pass filters are well suited for higher-order phase compensation.

TL;DR: It is shown that this solution is robust against channel-to-channel cross-talk from transparent nodes and does not suffer from performance degradation stemming from co-propagating 40 Gb/s channels.
Abstract: We report on the performance of 100Gb/s coherent non return-to-zero (NRZ-) polarization division multiplexed (PDM-) quadrature phase shift keying (QPSK) transmission over 16x100km of standard single mode fibre under constraints of typical transparent terrestrial networks, employing Erbium-Doped Fibre Amplifiers. We first evaluate the impact of cross non linear effects onto the performance of 100Gb/s coherent PDM-QPSK signals and we investigate the impact of shifting one of the polarization multiplexed tributaries by half a symbol duration with respect to the other one. Finally we show that this solution is robust against channel-to-channel cross-talk from transparent nodes and does not suffer from performance degradation stemming from co-propagating 40Gb/s channels.

TL;DR: In this paper, a theoretical and experimental analysis of thermal stress effects on the modal polarization properties of highly elliptical-core fibers is presented, based on solving the vectorial Maxwell's equations, using a finite-element scheme.
Abstract: A theoretical and experimental analysis of thermal stress effects on the modal polarization properties of highly elliptical-core fibers is presented. The theoretical analysis is based on solving the vectorial Maxwell's equations, using a finite-element scheme, when form-induced and stress-induced effects are introduced simultaneously through appropriate calculation of the refractive indexes of the anisotropic media. The experimental analysis is done by studying the temperature response of a white-light interferometric sensor employing highly elliptical-core fibers. The calculated temperature sensitivities of the modal birefringence and the polarization mode dispersion in highly elliptical-core fiber are in close agreement with the experimental results. Interpretation of the results useful for designing white-light interferometric sensors composed of highly elliptical-core fibers is also given.

TL;DR: It is demonstrated numerically that a compensation of the polarization mode dispersion can be observed for nonreturn-to-zero signals as a result of a trapping effect, in analogy to the well-known soliton behavior.
Abstract: We demonstrate numerically that a compensation of the polarization mode dispersion can be observed for nonreturn-to-zero signals as a result of a trapping effect, in analogy to the well-known soliton behavior. Conditions for such compensation are shown, and a comparison with the soliton case is reported.
