Abstract
An optical component, such as an optical receiver, is provided that includes a detector configured to receive a signal from an optical fiber and to communicate with a translationl module of the optical component. A transimpedance amplifier of the optical component is configured to receive an electrical signal from the detector and to transmit an amplified signal to the translation module. The transimpedance amplifier is configured for a controlled low cutoff frequency as optical power to the transimpedance amplifier increases, so that the optical sensitivity of the transimpedance amplifier is not traded for optical overload.
