This paper examines wavelength translation in all-optical wavelength-routed networks. Previous studies [4-7] have shown that wavelength translation can improve the blocking performance of these networks. However, all previous work [4-7] has assumed that Wavelength to any output wavelength. In contrast, all-optical wavelength translators demonstrated in the laboratory to date [9-11] are, in general, only capable of limited translation. In this paper we assess, for the first time, the network performance improvements offered by realistic all-optical wavelength translators with limited translation range. In particular, we consider all-optical wavelength translators based on four-wave mixing in semiconductor optical amplifiers. Using a simple model for their function, we consider the blocking performance of two-hop and multiple-hop paths, and unidirectional ring and mesh-torus networks. In all the cases we consider, significant improvement in the blocking performance of the network is obtained when limited-range wavelength translators with as little as one quarter of the full range are introduced. We also find that almost all of the network performance improvement offered by an ideal wavelength translator can be gained from a translator with only half of the full translation range.
