Transmission characteristics of multimode W-type optical fibers (doubly clad fibers with three layers) are investigated by solving the time-dependent power flow equation. A numerical solution has been obtained by the explicit finite difference method. Results show how the bandwidth in W-type optical fibers varies with depth and width of the intermediate layer for different coupling strengths and excitations. The trade-off between the bandwidth and steady-state loss is also specified. Such characterization of these fibers is consistent with their manifested effectiveness in reducing modal dispersion and bending loss. © 2013 Elsevier Ltd.
