Abstract
Systems and methods for processing an optical signal are disclosed. The optical signal is converted to a voltage signal and the voltage signal is amplified. In addition, a signal strength and/or a signal quality parameter is monitored and an indication of the signal strength and/or a signal quality parameter is generated. Further, a gain and/or an operating bandwidth on the conversion or the amplification can be adjusted based on the indication to reduce power consumption of an optical receiver.
