Abstract :The performance of 1 and 2 Mach--Zehnder modulator insert ignore into journalissuearticles values(MZM);-based simple carrier suppressed return to zero differential quadrature phase shift keying insert ignore into journalissuearticles values(CSRZ-QDPSK); transmitters is analyzed in a 20 Gb/s single-mode fiber optic link. The link`s performance under the transmitter schemes is evaluated by analyzing the received constellation, eye diagram, quality factor, and eye opening penalty insert ignore into journalissuearticles values(EOP); in a passive optical networks insert ignore into journalissuearticles values(PON); scenario. It is observed that the simple transmitter provides performance closer to the case of the standard 3 MZM CSRZ-QDPSK-based transmitter reported in the literature and implemented in experiments.
