ABSTRACT:
Disclosed is a single mode optical waveguide fiber which limits nonlinear effects at both the 1300 nm window and the 1550 nm window of operations. Examples of core region refractive index profiles which yield the required properties are a modified step index profile and profiles which have a maximum .DELTA.% which is spaced apart from the centerline of the waveguide fiber.
