Abstract :
Presented is a parametric tunable dispersion compensation (PTDC) for 43 Gbit/s WDM channels with mixed modulation formats of OOK and QPSK. The residual dispersion for the OOK channels is successfully compensated for, while the QPSK channels with digital coherent detection maintain a good signal quality regardless of various settings of PTDC that involve nonlinear processes of wavelength conversion based on four-wave mixing. Specific design issues on PTDC are discussed, considering the characteristics of the modulation formats of the received channels.
