1. A wavelength-switched reconfigurable optical add-drop multiplexer with wavelength broadcasting capability, comprising:

  • a wavelength selective switch comprising an input port operable for receiving an input optical signal and a plurality of output ports operable for outputting a plurality of output optical signals, wherein at least one of the plurality of output ports is designated as a broadcast port, and wherein the broadcast port is operable for outputting an output optical signal that is to be both locally received and broadcast; and

    a splitter coupled to the broadcast port of the wavelength selective switch, wherein the splitter splits the output optical signal outputted by the broadcast port into a locally received optical signal and a broadcast optical signal.
