Application of a Novel Modulation Scheme of PS-RZ-QPSK Signal in High-speed Optical Transmission System

摘要：

　　Modulation principle of dual-polarization quadrature phase shift keying signal and polarization-switched QPSK signal are demonstrated and advantages of PS-QPSK are proved in theoretically.A novel modulation scheme of PS-RZ-QPSK signal is proposed in this paper.The scheme reduces transmitter cost by less use of Mach-Zehnder modulator,but also presents similar performance as traditional structure for PS-RZ-QPSK.The simulate result indicates PS-RZ-QPSK can achieve a better transmission performance than DP-RZ-QPSK at the same bit rate (84Gb/s) and baud rate (28GBd),and proves showing the feasibility of novel modulation scheme.
