Comparative investigation and suitability of various data formats for 10 Gb/s optical soliton transmission links at different chirps

On the compensation of chirp induced from semiconductor optical amplifier on RZ data using optical delay interferometer

“…The format of the pulses is RZ so as to preserve the continuity with our previous relevant work [10][11][12][13], but also because this coding is preferable in terms of better receiver sensitivity and transmission performance compared to its NRZ on-off keying alternative [39,40], for which the nature of the pattern effect that has been addressed in [30] is less complicated [12,13]. Given now that in practice the quantity measured by the diagnostic equipment is the average power, P ave , it is necessary to define its relation to the peak power of the marks, P peak 1 , in order to be able to make the transition between experiment and theory in a straightforward manner.…”
