%X A performance comparison is made for the existing three types of PMD emulators:the emulators using rotatable sections (R-type),the emulators with polarization controllers (C-type) and the heater-based emulators (H-type).Statistical characteristics of the three PMD emulators are analyzed in detail,including probability distribution of differential group delay (DGD),high-order polarization mode dispersion (PMD) and frequency autocorrelation function (ACF).By using the number of segments as a major variable,it is found that DGD distribution generated by R-type emulator is more precise than C-type,and H-type the worst; for SOPMD generation,C-type emulator outperforms H-type,and R-type the worst; while in terms of ACF generation,H-type ranks the first.Judged by overall performance,C-type emulator is the best and capable of generating sufficient PMD emulation with as low as ten segments; however,for the same effects,over fifteen segments and over twenty segments will be required for R-type and H-type emulators,respectively.
