Abstract
The present claimed invention improves on the conventional comb and multiple router approach by making multiple use of a single router by using interleaved groups of wavelengths that enter through different entrance ports and exit through different groups of exit ports of the same router. This permits better separation (lower crosstalk) between adjacent channels, greatly reduced temperature sensitivity, small physical size and lower cost. With these improvements, a large number of wavelength add/drop sites may be cascaded in WAD/WDM systems.
