Abstract:
An optical fiber with ultra-low attenuation and bend insensitivity includes a core layer and cladding layers. The cladding layers have an inner cladding layer surrounding the core layer, a trench cladding layer surrounding the inner cladding layer, an auxiliary outer cladding layer surrounding the trench cladding layer, and an outer cladding layer surrounding the auxiliary outer cladding layer. The core layer has a radius of 3.0-3.9 μm, and a relative refractive index difference of −0.04% to 0.12%. The inner cladding layer has a radius of 8-14 μm, and a relative refractive index difference of about −0.35% to −0.10%. The trench cladding layer has a radius of about 14-20 μm, and a relative refractive index difference of about −0.6% to −0.2%. The auxiliary outer cladding layer has a radius of about 35-50 μm, and a relative refractive index difference of about −0.4% to −0.15%. The outer cladding layer is a pure silicon-dioxide glass layer.

Claim (Index 4):
The single-mode optical fiber according to  claim 1 , having a zero dispersion point of the optical fiber is in a range of 1300 to 1324 nm, and the zero dispersion slope of the optical fiber is smaller than or equal to 0.092 ps/(nm 2 *km).
