Jianchao Wang East Isle Technologies Inc., Setauket, NY 11733, USA Abstract—In this paper, we consider cost-effective designs of wavelength division multiplexing (WDM) optical switching networks for current and future generation communication systems. Based on different target applications: we categorize WDM optical switching networks into two connection models: the wavelength-based model and the fiberlink-based model. Most of existing WDM optical switching networks belong to the first category. In this paper we present new designs for WDM optical switching networks under both models by using sparse crossbar switches instead of full crossbar switches in combination with wavelength converters....
