Abstract
An optical receiver may include a photodetector that is configured to generate an electrical signal in response to detecting an optical signal, a first gain path coupled to receive and amplify the electrical signal generated by the photodetector, and a second gain path coupled to receive and amplify the electrical signal generated by the photodetector. The second gain path may have a higher gain than the first gain path. The two gain paths may be configured to amplify the electrical signal independently of each other. The optical receiver may also include a switch that selectably outputs an amplified electrical signal from one of the gain paths based on a magnitude of a signal corresponding to the optical signal.
