Abstract
The presence of vestigial-sideband optical filter, dispersion and chirp of modulator increases subcarrier to subcarrier intermixing interference (SSII), which significantly restricts transmission performance. For the first time, the iterative interference cancellation method is introduced to calculate and eliminate SSII. Furthermore, we successfully demonstrate a 40-Gbps, 16-QAM, dual drive Mach-Zehnder modulator (MZM)-based system transmission through 100-km uncompensated standard single-mode fiber. The impact of chirp on iterative algorithm is also experimentally evaluated by setting different optical phase modulation amplitudes on the two arms of the dual drive MZM.
