1. A reconfigurable optical add/drop multiplexer, comprising:

  • a first optical degree;

    a second optical degree;

    a common port having only one optical input and only one optical output, used to connect to a plurality of directionless add/drop ports; and

    a plurality of wavelength equalizers, each with only one optical input and only one optical output,wherein the plurality of wavelength equalizers are used to select wavelengths for the first optical degree and for the second optical degree and for the common port.
