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