Abstract: A communication method, apparatus, and system are provided, and belong to the field of communication technologies. The method includes: After receiving a first electromagnetic wave signal sent by a first adjacent node, a target third node performs target processing on the first electromagnetic wave signal to obtain a second electromagnetic wave signal, and sends the second electromagnetic wave signal to a second adjacent node. A first node, at least one third node, and a second node are sequentially disposed on a cable, and among these nodes, the target third node is adjacent to the first adjacent node and the second adjacent node. The target processing includes processing used to cause conjugate reversal of a spectrum of the electromagnetic wave signal.

Abstract: A signal receiving apparatus and method are provided. When a baseband signal is restored, an orthogonal polarization state of light does not need to be precisely controlled. This is easy to implement and can reduce system costs. The apparatus includes an optical splitter configured to split a first polarization multiplexing optical signal into at least two second polarization multiplexing optical signals, and input the two second polarization multiplexing optical signals into at least two optical signal processing modules. An optical signal processing module is configured to couple the second polarization multiplexing optical signal, and input a coupled optical signal to a photoelectric detector configured to convert the coupled optical signal into an analog signal. An analog-to-digital converter is configured to convert the analog signal into a digital signal, and input the digital signal to a digital signal processor configured to process the digital signal to obtain a baseband signal.
