A method and system for providing an a configurable optical add/drop module is disclosed. The method and system include providing first and second filters and a beam deflector between the filters. The first filter receives an input signal and an add signal, transmits a portion of the input signal to a drop signal, reflects a remaining portion of the input signal to an express channel and transmits the add signal. The second filter reflects the express channel to an output and transmits the drop signal and the add signal. The beam deflector has a first position and a second position. In the first position the beam deflector transmits the drop signal and add signal so the second filter transmits the drop signal to a drop output and the add signal to the output. In the second position the beam deflector deflects the drop signal and the add signal so the second filter transmits the drop signal to the output and decouples the add signal from the output.
