Most existing wavelength division multiplexing (WDM) optical interconnects make use of a large number of switching elements and require wide-range tunable wavelength converters to support full-connectivity among inputs and outputs. This results in complex and expensive designs. In this paper, we propose new full-connectivity single-stage and multi-stage WDM optical interconnects with and reduced hardware complexity. The proposed designs require a smaller number of switching elements and use only fixed-range wavelength conversion. Analysis of hardware complexity shows that, the proposed designs have a smaller number of switching and conversion costs compared to most existing interconnects
