We consider hybrid optical devices consisting of a waveband (transparent optical) and a wavelength (opaque OEO) switch. Such hybrid devices are suitable for supporting hierarchical optical paths (wavelength and waveband paths). We study the node-level cost-performance tradeoffs using both analytical models and simulations. The results demonstrate a significant cost reduction that could be achieved for a moderately small reduction of throughput.
