  • kerr nonlinearity mitigation mid Link spectral inversion versus digital backpropagation in 5 28 gbd pdm 16 qam signal transmission
    Journal of Lightwave Technology, 2015
    Co-Authors: Isaac Sackey, Francesco Da Ros, Johannes Karl Fischer, Thomas Richter, Mahmoud Jazayerifar, Christophe Peucheret, K Petermann, C Schubert
    Abstract:

    We experimentally investigate Kerr nonlinearity mitigation of a 28-GBd polarization-multiplexed 16-QAM signal in a five-channel 50-GHz spaced waveLength-division multiplexing (WDM) system. Optical phase conjugation (OPC) employing the mid-Link spectral inversion technique is implemented by using a dual-pump polarization-independent fiber-optic parametric amplifier and compared to digital backpropagation (DBP) compensation over up to 800-km in a dispersion-managed Link. In the single-channel case, the use of the DBP algorithm outperformed the OPC with a Q-factor improvement of 0.9 dB after 800-km transmission. However, signal transmission was not possible with DBP in the WDM scenario over the same Link Length while it was enabled by the OPC with a maximum Q-factor of 8.6 dB.

  • Estimation of Link-dependent parameters in optical transport networks from statistical models
    IEEE\ OSA Journal of Optical Communications and Networking, 2014
    Co-Authors: Sudhir K. Routray, Gokhan Sahin, José F. Rocha, Armando N. Pinto
    Abstract:

    Estimation of Link-dependent parameters of optical transport networks is quite complex without the availability of complete network information. However, at the network planning stage these estimations are to be done with incomplete information, and need to be accurate. In this paper, we provide effective methods to estimate Link-dependent parameters of optical transport networks when only partial information about the network is available. We use the Link Length statistical distribution model for these estimations. This approach is applied to 40 real transport networks and shown to be more accurate than the previously proposed methods. The improved accuracy of the proposed methods is achieved without extra network details: only the network node locations and the total number of Links are needed.

  • statistical model for Link Lengths in optical transport networks
    IEEE\ OSA Journal of Optical Communications and Networking, 2013
    Co-Authors: Sudhir K. Routray, Rui Manuel Morais, J R F Da Rocha, Armando N. Pinto
    Abstract:

    From the analysis of statistical properties of real networks, it is found that general extreme value (GEV) distribution provides an accurate model for Link Length statistics of optical transport networks (OTNs). The parameters of GEV distribution can be estimated from the average Link Length of the OTNs. Expressions for average Link Lengths, based only on the knowledge of network coverage area and number of nodes, are improved for better accuracy. It is shown that the optimized GEV distribution estimates the Link statistics of OTNs with good accuracy (Kolmogorov-Smirnov statistic less than 0.18).
