✦ Synopsis

We describe the effect of polarization mode coupling in the single-mode Ž . optical fibers on the extrema counting fixed analyzer FA polarization mode Ž . dispersion PMD measurement method. We define the polarization mode Ž . coupling coefficient for the over or under estimation which occurs with the FA method. We investigate the polarization mode coupling coefficient exper-Ž . imentally by comparison with the air-path cross-correlation type interferometric PMD measurement method. Moreover, we discuss the polarization mode coupling experimentally as well as analytically by using pseudo-polarization mode coupling which we obtained by splicing highly birefringent Ž y4 . Ž . B ( 4.5 = 10 polarization maintaining fibers PMFs with the random splice angles. The results show that the PMD of the single-mode optical fibers which has random polarization mode coupling can be approximated by multiplying the PMD obtained using the FA method with the random polarization mode coupling coefficient k ( 0.82.
