Multi-hump soliton which consists of plural pulses can propagate in a dispersion-managed optical fiber transmission system with maintaining the pulse-to-pulse spacings. In this paper, the family members of multi-hump soliton are systematically introduced using a family tree. The system parameter ranges in which multi-hump soliton can exist are studied by a numerical averaging scheme. The dependency of pulse energy and pulse-to-pulse spacing on the system parameter is also investigated to show the robustness of anti-phase bi-soliton against imposed perturbations.
