A single mode optical waveguide fiber having a core refractive index profile of at least four segments is disclosed. The main features of the core design are: at least two non-adjacent core profile segments have positive INCREMENT %; are, at least two non-adjacent segments have negative INCREMENT %, The novel waveguide core design provides a single mode waveguide which is suitable for high rate, long regenerator spacing systems which incorporate optical amplifiers. The waveguide core structure also lends itself to the manufacture of dispersion managed waveguide fiber. |
