ABSTRACT:
A layered optical cross-connect switches signals from a first set of optical fibers to a second set of optical fibers. The optical cross-connect comprises at least two switching layers. The input ports and the output ports of each switching layer are fully interconnected. At least one switching layer is configured to switch at least two signals from the same optical fiber from the first set of optical fibers to the second set of optical fibers. For example, in a wavelength-division multiplex (WDM) system, a switching layer can switch signals from different WDM channels having different wavelengths.
