The analytical expression of the chirp caused by the cross-phase modulation effect in the presence of fiber loss is introduced.The chirp evolution process is simulated by computer and the relationship between chirp and fiber loss coefficient and group velocity mismatch is analyzed.The results show that the chirp The chirp is less affected by the fiber loss; it is more affected by the group velocity mismatch; the chirp tends to be stable after a period of optical fiber evolution.
