OPTICAL RECEIVING APPARATUS, OPTICAL RECEIVING PACKAGING APPARATUS, AND RELATED DEVICE AND METHOD

This application provides an optical receiving apparatus, an optical receiving packaging apparatus, and a related device and method. The optical receiving apparatus may include a decoupling module, a voltage regulator module, an optical-to-electrical conversion module, and an amplifier module. The decoupling module is configured to perform direct current removal processing on a first electrical signal to obtain a second electrical signal. The second electrical signal is a pulse signal. The first electrical signal and the second electrical signal carry control information for controlling a working state of the amplifier module. The voltage regulator module is configured to perform voltage regulation processing on the first electrical signal to obtain a third electrical signal with a constant amplitude. The optical-to-electrical conversion module is configured to receive a burst optical signal, and convert the received burst optical signal into a fourth electrical signal. The amplifier module is configured to amplify the fourth electrical signal under control of the control information in the second electrical signal and power supply of the third electrical signal, and output the amplified fourth electrical signal. According to this application, a requirement for a signal pin of an optical receiver in a PON system can be reduced, thereby reducing packaging costs of the optical receiver.
