摘要：Advance modulation format such as carrier suppressed return to zero (CSRZ) is used in several optical communication systems. The generation of CSRZ signal is reported in this paper by means of allphotonics format converter to its suppressed carrier signal. It examines five photonics signals of NRZ, RZ, CRZ, soliton and duobinary. All formats are successfully converted to the carrier suppressed return to zero, CSRZ. The converter utilizes the semiconductor optical amplifier in a loop mirror and the control signal which is typically at ten times higher than the input signals. The suppressed signal can reduce the peak power alteration in the transmission. It also minimizes the nonlinear effects due to unavailability of the peak carrier. The CSRZ in the WDM system with 4 and 8 channels shows soliton as the best suppressed signal within selected parameters.
