摘要：
The present invention relates to an optical transmitter for generating a duobinary Carrier Suppressed Return-to-Zero (CSRZ) optical signal and a CSRZ-Differential Phase Shift Keying (DPSK) optical signal for use in an optical communication system. The optical transmitter includes a data encoder, an electric mixer and a single Mach-Zehnder interferometer type external, and is capable of reducing the optical spectrum bandwidth of the optical signal using electrical band limiting and reducing the optical signal distortion caused by Group Velocity Dispersion (GVD) in an optical fiber.
