Abstract
An optical receiving apparatus includes a decoupler, a voltage regulator, an optical-to-electrical converter, and an amplifier. The decoupler receives a first electrical signal, and performs direct current removal processing on the first electrical signal thereby obtaining a second electrical signal. The first electrical signal includes control information to control a working state of the amplifier. The electrical signal is a pulse signal and includes the control information. The voltage regulator receives the first electrical signal, and performs voltage regulation processing on the first electrical signal thereby obtaining a third electrical signal that has a constant amplitude and provides a voltage for the amplifier. The optical-to-electrical converter receives a burst optical signal, and converts the burst optical signal into a fourth electrical signal. The amplifier amplifies the fourth electrical signal based on the control information and a power supply of the third electrical signal, and outputs an amplified fourth electrical signal.
