A communication system comprises the network, plural nodes, and a reducer. The network comprises a main line and a plurality of branch lines branched from the main line respectively, the main line and each of the branch lines being respectively formed into a differential two-wire type of communication line consisting of a first communion line and a second communication line. The plural nodes are connected to two or more branch lines of the branch lines to communicate frames of data among the branches with each other. The reducer is arranged to each node to reduce either an impedance of each of the first and second communication lines or an impedance between the first and second communication lines during a specified period of time starting at a time instant when a node completes sending out the frames of data to be transmitted.
