Theoretical basis of spun fibers and their ability to reduce Polarization Mode Dispersion (PMD) are discussed. In order to overcome PMD-based problems, Amplitude Modulation Transmitted Carrier (AM-TC) profile is proposed. A comparative analysis of spin profiles is made and spin parameters giving successful results for low-PMD fibers are obtained. Simulation results show that for spin period of I m and spin amplitude of 2.76 turns/in, the proposed AM-TC spin profile provides better PMD reduction results than the conventional ones. For different modulation index values of the AM-TC spin profile, the differential group delay (DGD) obtained is under 1.4 fs.
