1. A method, comprising:

  • generating a first passive optical network (PON) protocol message, wherein the first PON protocol message comprises a first action indication indicating that the PON user terminal intends to exercise a first power supply mode that is a power-saving mode, wherein the first power supply mode is operated at lower power than a power provided in a second power supply mode, wherein in the second power supply mode, a power supply is provided to the PON user terminal such that the PON user terminal can provide service data from an optical line termination (OLT) to a user and communicate with the OLT via an established upstream connection;

    sending the first PON protocol message;

    entering the PON user terminal in the first power supply mode, wherein in the first power supply mode, both upstream communication and downstream communication with the OLT are disabled to break, while retaining the ability to switch from the first power supply mode to the second power supply mode.
