1. A receiving end, comprising:
a first high-speed signal optoelectronic transmission module and a first low-speed signal optoelectronic transmission module, wherein:
a power supply port of the first high-speed signal optoelectronic transmission module connects to a high-speed signal line of the receiving end, and a power supply port of the first low-speed signal optoelectronic transmission module connects to the high-speed signal line of the receiving end through a power switch;
wherein the receiving end is configured to:
before plugging into a destination end, the first high-speed signal optoelectronic transmission module acquires electric power from the high-speed signal line of the receiving end; wherein, after the first high-speed signal optoelectronic transmission module receives a first preset high-speed light signal or a second preset high-speed light signal transmitted from an optical fiber, setting, by the first high-speed signal optoelectronic transmission module, a light signal idle flag thereof to an invalid state,
the first preset high-speed light signal is a high-speed light signal converted from a high-speed electrical signal generated when a sending end, corresponding to the receiving end, monitors a second low-speed electrical signal on a low-speed data line of the send end;
the second preset high-speed light signal is a high-speed light signal converted from a second preset high-speed electrical signal sent after a source being awakened; and
in response to the light signal idle flag of the first high-speed signal optoelectronic transmission module being in the invalid state, the power switch is turned on, accordingly the first low-speed signal optoelectronic transmission module acquires electric power from the high-speed signal line of the receiving end, and the first low-speed signal optoelectronic transmission module starts working normally.
