Effect of local PMD and PDL directional correlation on the principal state of polarization vector autocorrelation

Abstract

The effect of local PMD and PDL directional correlation is considered for the first time in a single mode fiber communication link. It is shown that the autocorrelation between the real and imaginary part of the complex principal state vector is nonzero in general. Experimental results verifying the local correlation between PMD and PDL directional are reported.

Polarization effects in aerial fibers

“…Similarly the experimental mean square PDL η 2 experiment could be different from the pristine mean square PDL η 2 . It is important to note the mean square pristine DGD and mean square pristine PDL can be found by the following coupled equations that are valid in the highly mode-coupled limit [20]:…”

“…This information is especially useful for the mitigation of PMD. ACF's over frequency and time for the PMD vectors magnitude and direction have been derived [19,20,22]. In aerial fibers the interesting quantity is the time drift ACF.…”

“…In our calculation, we choose local correlation α ·β = N j =1α j ·β j /N = 0.2, which according to Chen et al [10,12] is a typical number for field fiber.…”
