    The application of low-cost optical pulse source will redound to the practical development of optical code-division multiple-access (OCDMA) system. The application of practical chirped optical pulse source in OCDMA system is improved. The effect of chirp elimination on decoding performance is investigated;The half-side bandwidth of encoding spectrum is utilized for encoding and decoding in order to improve the decoding performance in terms of the fact that the spectrum of common practical chirped pulse source is not wide enough to cover the whole encoding spectrum. The simulation and experimental measured data show that the decoding peformance can be improved via chirp elimination and further optimized by the full utilization of laser source spectrum due to the half-side bandwidth encoding and decoding. The results indicate that the application of chirped optical pulse source in OCDM can be optimized and improved effectively by chirp elimination and half-side bandwidth.
