Abstract:
1. A non-zero dispersion shifted optical fiber, comprising: a central core having an outer radius r a first intermediate cladding positioned between said central core and said outer cladding, said first intermediate cladding having an outer radius r a buried trench positioned between said first intermediate cladding and said outer cladding, said buried trench having an outer radius r wherein said central core's outer radius r wherein said central core's maximum refractive index difference Dn wherein, for a radius of curvature of 30 millimeters at a wavelength of 1625 nanometers, the optical fiber exhibits bending losses of less than 0.5 dB/100 turns; and wherein, at a wavelength of 1550 nanometers, the optical fiber's effective area is 95 μm
