Abstract :
Proposing a photonic transmission system generated by Mach-Zehnder (MZ) modulator, that is based on binary phase shift keying(BPSK) and quadrature PSK(QPSK) and amplitude shift keying (ASK) modulation limits and spectral efficiency have been considered, simulation models are developed for evaluation of the system transmission performance. The multi-level optical signal spectra, eye diagrams and bit error rates are obtained to demonstrate the lightwave modulated multi-level scheme transmission over the dispersive single mode optical fibers.
