Novel C-IPDM signal format for suppression of polarization mode dispersion
A novel chirped intra-bit polarization diversity modulation (C-IPDM) signal format is proposed. The transmission performance of C-IPDM is compared to NRZ, RZ and the common IPDM in terms of the PMD tolerance by simulation in a 40 Gb/s system. The results show that the C-IPDM format can reduce the effects of second-order PMD significantly due to the chirping characteristic and the system Q-factor is increased especially in high PMD systems.
