A novel transmitter configuration generating SB-DCSRZ signal and EB-CSRZ-DPSK signal is presented. The method is potentially cost-effective due to the simple configuration, and more dispersion tolerant due to the electrically band-limiting. Compared with EB-CSRZ signal, improvement of dispersion tolerance is reduced for EB-DCSRZ signal and enhanced for EB-CSRZ-DPSK signal, while signal distortion is improved for EB-DCSRZ signal and deteriorated for EB-CSRZ-DPSK signal.
