Graded index multimode fibers are far more complicated than their single mode counterparts. The relevant expressions are stated to permit insight into the relationships between material properties and fiber performance. The index profile as a function of radius r is given by Equation 4. For such a profile, the intermodal group delay may be approximated by... [Pg.178]
