An object of the present invention is to provide an optical communication system that can reduce costs and improve the operation of an optical fiber network. In an optical communication system 301 according to the present invention, power supply light is supplied from a parent node 10 to a child node 20 through an optical fiber 52, the parent node 10 superimposes a signal on the power supply light and transmits a reset signal to one child node 20 through the optical fiber 52, the child node 20 receives the reset signal from the optical fiber 52 to reset itself, the parent node 10 superimposes a signal on the power supply light and transmits a reset completion confirmation signal to the child node 20 through the optical fiber 52, the child node 20 intensity-modulates the power supply light supplied from the parent node 10 to generate a response signal, and transmits the response signal to the parent node 10 through the optical fiber 52 after resetting itself and after receiving the reset completion confirmation signal, and the parent node 10 determines success or failure of resetting the child node 20 based on the presence or absence of the response signal transmitted from the child node 20 through the optical fiber 52.
An optical communication system in which one parent node and one or more child nodes are connected by an optical fiber for a main signal and an optical fiber for optical power supply, and light for driving power is supplied from the parent node to the child node through the optical fiber for optical power supply, wherein the parent node superimposes a signal on the light for driving power and transmits a reset signal and a reset completion confirmation signal to any one of the child nodes through the optical fiber for optical power supply, and the parent node determines success or failure of resetting the child node based on presence or absence of a response signal transmitted from the child node through the optical fiber for optical power supply, and the child node receives the reset signal from the optical fiber for optical power supply to reset the child node itself, and after resetting the child node itself and after receiving the reset completion confirmation signal, the child node superimposes a signal on the light for driving power supplied from the parent node to generate the response signal, and transmits the response signal to the parent node through the optical fiber for optical power supply.
A reset method for resetting a child node in an optical communication system in which one parent node and one or more child nodes are connected by an optical fiber for a main signal and an optical fiber for optical power supply, and light for driving power is supplied from the parent node to the child node through the optical fiber for optical power supply, the reset method comprising:
