Structural design of multimode graded-index fibers in the long-wavelength region around 1.3 µm is described. Suitable fiber parameters for operating with a laser source for determined: outer diamter 125 µm, core diameter 50 µm, and refractive-index difference 0.015 (relative-index difference ~1%), for transmission systems around 100 Mb/sec. These values agree with the optimum values for short-wavelength transmission systems.
