1. A system for creating a wave division multiplexing virtual private network by dynamically adding/dropping wavelengths in a reconfigurable optical add-drop multiplexer (ROADM) transport network having at least one optical transponder, comprising:

  • a plurality of optical fan-out devices, each arranged to receive an input signal from a network degree and coupled to at least one of a plurality of optical fan-in devices, each optical fan-in device arranged to output a signal to a network degree, the optical fan-out devices comprising at least one wavelength selective switch and the optical fan-in devices comprising at least one wavelength selective switch, the optical fan-out devices and optical fan-in devices being connected so as to enable signals input from each of the plurality of network degrees to be switched to another network degree of the plurality of network degrees;

    a plurality of demultiplexers for locally dropping selected wavelengths;

    a plurality of multiplexers for locally adding selected wavelengths; and

    at least one customer-dedicated fiber switch interposed between the at least one optical transponder and the plurality of demultiplexers and multiplexers, the customer-dedicated fiber switch being coupled to wavelengths and degrees to reserve wavelengths for the customer.
