A controllable optical amplifier module is disclosed. The controllable optical amplifier module includes a signal line. The signal line includes an input for receiving an input signal, an output for discharging an amplified signal such that the output is optically connected to the input, a gain medium optically disposed between the input and the output, and a first tap for generating a first tapped signal such that the first tap is optically disposed between the input and the output. The controllable optical amplifier module also includes at least one pump laser having a laser output optically connected to the gain medium and an ability to adjustably alter the intensity of the amplified signal. A method of adjustably amplifying an optical signal is also disclosed.
