Abstract
A modified carrier suppressed return-to-zero (CSRZ) format was forward in this paper, and it helps to improve the extinct ration (ER) and signal-to-noise ration (SNR) of the transmitted signal. Experiment of 2560km error-free transmission in straight line without forward error correction (FEC) and electric regeneration was demonstrated in this paper to evaluate the performance of modified CSRZ, and chirped fiber Bragg grating (CFBG) employed as the dispersion compensator in this transmission system. The experiment result showed that if the modified CSRZ format was applied in this 2560km transmission, less than 2.5dB power penalty was cost after 2560km transmission, and on the other hand, error-free transmission could not be got in the conventional NRZ-based CFBG-compensated system.
