【Abstract】 Importance sampling technique is used to evaluate the bit error probability of a wavelength channel in WDM networks, the homodyne crosstalk of OXC and the ASE noise of EDFA are considered. The impact of the WDM wavelength number, same-source crosstalk number and the extinct ratio on the system performance is discussed.更多还原
