Abstract
The origin and characteristic of chirp in external modulator are discussed in this paper. The effect of chirp on dispersion compensation system is analyzed through numerical simulation method. With small negative chirp
electrical eye open penalty (EOP) at the transceiver output end can reduce 0.5dB
which demonstrates that system performance is improved.
