Abstract
A gradient optical fiber with an optimized index of refraction profile characterized by the normalized difference in the index of refraction .DELTA. is in a range of 0.005 to 0.011, with -(k.sub.o /.DELTA..multidot.d.DELTA./dk.sub.o) being in a range of 0.09 to 0.11, an index of refraction profile function f(r/a) according to a formula of f(r/a)=(r/a).sup..alpha.+ A((r/a).sup..alpha.- (r/a).sup.2.alpha.) and a profile dispersion function F.sub.N according to F.sub.N =f.sup.g wherein .alpha. is in the range of 2.013 to 2.015, A is in a range of 0.114 to 0.116, and g is in a range of 2.4 to 2.6.
