Abstract
The present invention provides a communications method of a modem, including: determining a current power supply mode; if it is determined that the current power supply mode is that a network device is used to supply power by using a copper twisted pair, switching a communications interface from a fiber interface to an electrical interface, where the electrical interface connects to the network device by using the copper twisted pair and the fiber interface connects to a passive optical network by using an optical fiber. The present invention further provides a modem, and a wireless charging method and device. According to the technical solutions provided in the present invention, it is implemented that a service can still be provided after an external power supply is powered off.
