            Abstract : 
We review the causes of pulse broadening in multimode fibers with special emphasis on the importance of designing and producing fibers whose refractive index profiles conform to a theoretical optimum. Also discussed are attempts to broaden the wavelength range of high signal bandwidth by use of fiber cores produced with multiple dopants.
