摘要: A system for controlling an optical intensity and modulation of data transmitter which includes current driver circuitry configured to provide a drive laser diode wherein said comprises fixed component modulated component, having magnitude related input stream. The monitor contains photodiode first transimpedance amplifier coupled photodiode, output signal diode. further replica containing capacitor with capacitance second be substantially identical in construction amplifier, capacitor. control match associated photodiode.
