Optical fibre with large effective area and strong chromatic dispersion

机译:有效面积大,色散强的光纤

摘要

Optic fiber with wavelength of 1550 nm has effective surface larger than or equal to 100 square microns, chromatic dispersion larger than or equal to 14 ps/(nm.km), and sensitivity to microbending lower than or equal to 1. For a long wave of 1550 nm. the chromatic dispersion is less or equal to 21 ps/(nm.km). Refractive index profile is coaxial-type index profile with ring having, starting from center of fiber: first central section with slightly constant index; first annular section with index larger than index of sheath, and larger than index of central section. Both sections form coaxial profile. Around first annular section, fiber has buried section with index lower or slightly equal to index of sheath, then second annular section with index larger to index of sheath, forming ring around coaxial profile. An Independent claim is also included for a transmission system
