Abstract
An example optical receiving device includes a photodiode to receive an optical signal, where the photodiode is configured to conduct a current that is based on an optical power of the optical signal, and a radio frequency (RF) gain circuitry to generate one or more analog electrical signals based on the current and based on gain provided by the RF gain circuitry. A power detector is configured to receive an analog electrical signal of the one or more analog electrical signals, to detect alternating current (AC) power of the optical signal based on the analog electrical signal, and to output a signal representing the AC power based on the detecting.
