Time evolution of PMD due to tides and sun radiation on submarine fibers

摘要

Using a fast polarization mode dispersion (PMD) set of 15-s interval and long measurement duration (>24 h), we found the correlation between polarization effects, tides and sun radiation on submarine fibers. We also found Maxwellian distribution for the differential group delay (DGD) even with strong biased output states of polarization (SOP) over 1 h measurement. PMD bandwidth and the fastest decorrelation time were calculated to be 165 GHz and less than 15 s.
