Abstract

A low loss buffered optical waveguide fiber is described. An optical waveguide fiber is coated with a first layer of high modulus material applied to the exterior longitudinal surface thereof. Thereafter, a second layer of low modulus plastic material is disposed over the layer of high modulus material. The ratio R.sub.i /R.sub.o of the radii of the first and second applied layers is selected to minimize the microbending loss.
