Abstract
An optical transmitter of CS-RZ modulation for further increase the SPM-GVD resistance and an optical fiber transmission system having the same are disclosed. The optical transmitter comprises a carrier source, a data modulating section for intensity-modulating the carrier with a data signal, a clock modulating section for amplitude-modulating the carrier so that the phase of the carrier is inverted for every one-bit slot of the data signal. The optical transmitter is characterized in that the carrier is given a prechirp by the carrier source or the data modulating section.
