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. I
