摘要： 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.

摘要： A transmission cable is provided to implement high-speed inter-device interconnection and intercommunication. The transmission cable includes a positive dispersion transmission section, a negative dispersion transmission section, and a dispersion matching section. A cross-sectional diameter of the positive dispersion transmission section is less than a cross-sectional diameter of the negative dispersion transmission section. The dispersion matching section is configured to connect the positive dispersion transmission section and the negative dispersion transmission section. The transmission cable can implement dispersion cancellation to reduce total group delay.
