The propagation of solitary waves (solitons) in communication line is investigated. The solitons are generated in the non-linear dispersion transmission line. It is presented as non-linear circuit with distribution parameters, which include non-linear capacitors. The non-linear circuit consists of multiple sections, which included inductance, capacitor and non-linear capacitor. The variable capacitance diode as non-linear capacitance is used. The sine generator in the input of non-linear circuit is connected. The investigated transmission line as load in the end on nonlinear circuit is connected. In this case, the load is presented as linear circuit with distribution parameters. The propagation of solitons along the linear circuits with losses is investigated. Two cases of presentation linear circuits are investigated: only ideal R sections and RL sections. By relative length of load the soliton amplitudes decrease materially. This decrease is bigger by RL load. The influence of load length on the amplitude of biggest solitons is detected.
