We have estimated the effective α-parameter of the extended transmitters in the presence of self-phase modulation (SPM) induced chirp. The α-parameter of transmitters is effectively lowered to about 1, when the SPM effect is included, compared to the α-parameter of the transmitter alone. This lowered effective α-parameter has improved the transmission performance significantly regardless the transmitter is operated with positive or negative chirp. The SPM-induced effective α-parameter can be used as a design parameter for the high-speed (10 Gb/s) transmission systems.
