Abstract (en)

[origin: WO2005122479A2] There is provided a multiport variable optical attenuation architecture, including a first optical signal manipulating means coupled to the input means, to manipulate optical signals input thereto and output first manipulated optical signals; a second optical signal manipulating means arranged to receive the first manipulated optical signals from the first optical manipulating means, and to adaptively manipulate the received first manipulated optical signals input thereto so as to output second manipulated optical signals; and a third optical signal manipulating means arranged to receive the second manipulated optical signals, and to a predetermined manipulation of the second manipulated optical signals so as to output an attenuated signal.
