In this work, the bending loss was numerically studied within the COMSOL environment, where the general formula for profile index including graded and step-index types was adopted. The study showed an increase in bending loss with decreases bending radius, decreases core radius and increases wavelength. The graded order is effective up to after which the loss is constant. There is an oscillating change in loss caused by interference between the outgoing and reflected waves from the boundaries, which becomes clearer as the loss itself increases.
