This study presents a novel transmitter configuration generating electrically band-limited carrier suppressed return-to-zero (EB-DCSRZ) signal and electrically band-limited carrier suppressed return-to-zero differential phase shift keying (EB-CSRZ-DPSK) signal. The proposed method is potentially cost-effective due to the simple configuration, and more dispersion tolerant due to the electrically band-limiting signal. Compared with EB-CSRZ signal, improvement of dispersion tolerance was reduced for EB-DCSRZ signal and enhanced for EB-CSRZ-DPSK signal, while signal distortion was improved for EB-DCSRZ signal and deteriorated for EB-CSRZ-DPSK signal.
