ABSTRACT We numerically study polarization-mode dispersion in fiber routes with a finite number of degrees of freedom, show that individual channels in such systems exhibit a non-Maxwellian differential group delay distribution, and analyze the resulting statistics of outage probabilities. We show that a significant number of channels in such systems will be outage-free for long time periods.

    ABSTRACT: Using the Jones matrix eigenanalysis method, the differential group delay (DGD) behavior of a metropolitan G.652 buried operational cable plant of a major Italian telecom operator in the city of Torino was characterized. The measurement campaign lasted 73 consecutive days. An extremely stable DGD behavior was found, despite the fact that the cables run across a very densely built city environment. On the other hand, it was also found that routine maintenance on the infrastructure, although indirect and nondisruptive, repeatedly altered this picture. Based on these results, it is argued that the recently introduced "hinge" model describes the plant DGD statistical behavior better than the traditional description. This argument is also supported by the close fit that was obtained with a theoretical hinge-model DGD probability density function of the measured DGD data histogram. It is also argued that in this kind of scenario fast adaptive compensation is most likely the only realistic solution for avoiding sudden performance degradation or out-of-service

    Article: Practical Solutions to Polarization-Mode-Dispersion Emulation and Compensation

    ABSTRACT: Polarization-mode dispersion (PMD) still remains a challenge for high-data-rate optical-communication systems. Practical solutions are desirable for PMD emulation, monitoring, and compensation. The authors review and compare various techniques for PMD emulation and compensation, with an emphasis on the application of programmable differential-group-delay (DGD) elements for manipulating PMD effects. The authors pay special attention to advanced emulation techniques, such as importance sampling and the hinge model, for practical applications. The tunability of programmable DGD elements proves to be attractive for both system performance evaluation and overall optimization

    Article: Noncompliant Capacity Ratio for Systems With an Arbitrary Number of Polarization Hinges

    ABSTRACT: We study the statistics of transmission impairments due to polarization-mode dispersion in systems characterized by the hinge model. In particular, we validate the use of a computationally efficient expression for the probability density function (PDF) of the differential group delay (DGD) of systems with an arbitrary number of hinges. We then combine this expression for the PDF of the DGD with the outage map approach to compute outage probabilities and noncompliant capacity ratios for transmission links with varying numbers of sections (from 4 up to 20), each for several values of mean DGD and different system parameters.
