Optical Receiver with a Wide Power Sensitivity Dynamic Range

摘要

An optical receiver system includes a power adjustment device, an optical receiver, and a controller. The power adjustment device adjusts the power of an optical input signal in accordance with adjustment instructions. The optical receiver converts the power-adjusted optical input signal into an electrical signal that corresponds to a desired channel of the optical input signal. The optical receiver includes an electronic amplifier that amplifies the electrical signal using a gain value, and the amplified electrical signal preferably operates around a voltage value V_opt. The controller determines adjustment instructions such that the power adjustment device adjusts the optical input signal to a target optical power level that corresponds to V_opt for the amplified electrical signal, wherein the adjustment instructions are derived from the amplified electrical signal.
