A system for hybrid electronic/photonic switching of traffic in a node of
a communications network includes a plurality of interfaces; an
electronic cross-connect (EXC); and a photonic cross-connect (PXC). Each
interface is designed to translate a respective traffic stream between
corresponding electronic and optical signals. The EXC selectively maps an
electronic signal through a selected one of the interfaces, and the PXC
selectively couples an optical signal between the selected interface and
a selected one of at least two optical channels of the communications
network.
