  • High dispersion zero waveguide fiber
    Patent number: 6754424
    Abstract: Disclosed is a single mode optical waveguide fiber designed for use in high performance telecommunication systems. The novel core profile design improves bending performance to provide enhanced resistance to adverse environments. Total dispersion over an extended wavelength window is maintained low by placing the zero dispersion wavelength above the upper limit of the operating window. In addition, cut off wavelength is increased to just below the operating window. Ease of manufacture is retained as is very low waveguide attenuation.
