TLDR
In this article, the authors analyzed PMD impairments in 112-Gb/s PDM-QPSK coherent systems and quantified outage probabilities, showing that 1st-order PMD under-estimates PMD impairment, but modeling 2nd-orderPMD as polarization-dependent chromatic dispersion significantly over-estimated PMD penalties.Abstract:
We analyze PMD impairments in 112-Gb/s PDM-QPSK coherent systems and quantify outage probabilities. We show that 1st-order PMD under-estimates PMD impairments, but modeling 2nd-order PMD as polarization-dependent chromatic dispersion significantly over-estimates PMD penalties.read more

End-to-End Energy Modeling and Analysis of Long-Haul Coherent Transmission Systems
Bipin Sankar Gopalakrishna Pillai,Behnam Sedighi,Kyle Guan,N. Prasanth Anthapadmanabhan,William Shieh,Kerry Hinton,Rodney S. Tucker +6 more
TL;DR: It is found that receiver energy consumption dominates in transmission systems that use electronic dispersion compensation over long transmission distances, and for short transmission distances where hard-decision decoding is adequate for both modulation formats, DP-16-QAM is more energy efficient than DP-QPSK.

Impact of nonlinear and polarization effects in coherent systems
TL;DR: Recent advances in understanding the impact of fiber nonlinearities, polarization-mode dispersion, and polarization-dependent loss on PDM-QPSK coherent systems are reviewed.

Intra- Versus Inter-Channel PMD in Linearly Compensated Coherent PDM-PSK Nonlinear Transmissions
TL;DR: It is shown that on average PMD improves the performance of dispersion-managed links by reducing both nonlinear interactions among signals and nonlinear phase noise, while it has no effect in non-dispersion managed links.

Joint Scheme of Dynamic Polarization Demultiplexing and PMD Compensation Up To Second Order for Flexible Receivers
TL;DR: A novel dynamic polarization demultiplexing scheme using extended Kalman filter (EKF) in digital signal processing of flexible receivers that can track up SOP rotations more than 35 times and 50 times faster than that of constant modulus algorithm (CMA) and CMA/multiple modulus algorithms (MMA), respectively.

Polarization-mode dispersion in high-speed fiber-optic transmission systems
TL;DR: In this article, the benefits of using different passive techniques for mitigating the effects of polarization mode dispersion in fiber-optic transmission systems operating at 40 Gb/s and above are investigated.

The statistics of PMD-induced chromatic fiber dispersion
TL;DR: In this paper, the authors present a statistical description of polarization dependent chromatic dispersion in optical fibers due to second-order polarization mode dispersion (PMD), which is the cause of pulse broadening and compression of the signal components propagating in the principal states of polarization.

Observation of PMD-induced coherent crosstalk in polarization-multiplexed transmission
TL;DR: In this paper, the worst case impairments caused by first-order polarization-mode dispersion (PMD) in the fiber were investigated with both polarization-division multiplexing using two polarizations at each wavelength and polarization interleaving where adjacent channels have orthogonal polarizations.

Emulation and inversion of polarization-mode dispersion
TL;DR: In this article, the authors review the principal concepts and theory employed in approaches to PMD inversion and in the closely related emulation of PMD vector data and discuss three second-order emulator models and the distinction between the PMD vectors and the eigenvectors of the fiber's Jones matrix.
