The effects of the position of dispersion compensation fiber on 4 X 10Gb/s WDM systems with different duty cycle are investigated. With the long amplifier spacing and large input power, no matter what the duty cycle is, the performance of the system with DCF-first is worse than that with SMF -first; The best performance can be obtained with duty cycle of 0.5, and it is independent of the position of DCF. With the short amplifier spacing and small input power, the system performance with NRZ format and DCF-first is better than that of other systems. It means that NRZ format and DCF-first should be employed in WDM system with short amplifier spacing.
