In this paper, we discuss the tensor mode perturbation in the frame of loop quantum cosmology with higher order holonomy corrections. We get the dynamics of the background near the bounce and far from the bounce. Based on the solutions of the effective Friedmann equation, we deduce the effective gravitational wave equation and get the quantum corrections in both the mass term and source term. We solve the gravitational wave equation near the bounce and discuss the situation far from the bounce. We also find the new terms arose only when one considers the higher order corrections.
