Abstract :
The effects of limited-range wavelength conversion on the performance gain of survivable WDM networks are studied in this paper. Two kinds of limited-range wavelength conversion technologies are considered: FWM (SOA in four-wave mixing), XGM (SOA in cross-gain modulation). By simulation in two networks: NSFNET (the U.S national science foundation backbone network) and CERNET (Chinese education and research network), the blocking performance of WDM networks with above limited-range wavelength conversions are studied. The results show that when the WDM networks consider lightpath protection, the performance gain of wavelength conversion increases compared with that without protection. The performance gain offered by FWM wavelength converters is superior to that of XGM. The performance of XGM wavelength converter is close to that of FWM wavelength converter with very small conversion range.
