  • Patent number: 9794020
    Abstract: A method and system for distributed spatial mode processing is disclosed. A number of optical signals are received over an optical link. Each optical signal is received via a respective one of a number of spatial modes of the optical link. The optical link includes a particular spatial mode not used for the receiving. A first one of the number of optical signals received from a first one of the number of spatial modes is transferred to a second one of the number of spatial modes via the particular spatial mode, wherein the first one of the number of optical signals is transmitted via the second one of the number of spatial modes.
    Type: Grant

  • Patent number: 7587142
    Abstract: A method and system for estimating a fraction of an optical transmission system's transmission window that is compliant with the system's polarization mode dispersion (PMD) outage specifications, the optical transmission system including Ns optical fiber segments. The method comprises the steps of: propagating a plurality of optical signals through the Ns optical fiber segments; monitoring the differential group delay (DGD) for each optical signal over time; computing a time average and variance of the monitored DGD for each optical signal; computing statistics of the time averages and variances of the monitored DGD for each optical signal; determining the number of effective PMD sections and effective hinges in the system from the statistics; and determining the size of a PMD capacity compliant fraction for a specified outage probability.

  • Publication number: 20090135408
    Abstract: A methodology, device and memory medium for measuring the polarization mode dispersion (PMD) of an optical fiber is disclosed. The root mean square (rms) differential group delay (DGD) of fiber sections is estimated, the multisection DGD value ?? is calculated, and a determination is made as to how much the value ?? is likely to differ from the true mulitsection rms value ??rms.
