Abstract
In one aspect of the invention, the bend insensitive single-mode optical fiber includes a core layer and cladding layers having an inner cladding layer, a trench cladding layer and an outer cladding layer sequentially formed surrounding the core layer from inside to outside. For the core layer, the diameter is 7-7.9 μm, and the relative refractive index difference Δis between 4.6×10and 6.0×10. For the inner cladding layer, the diameter is 15-17 μm, and a relative refractive index difference Δis between −3×10and 3×10. For the trench cladding layer, the diameter is 24-33 μm, and the relative refractive index difference Δis between −2.9×10and −7.3×10, changes in a gradient manner and increases gradually from outside to inside, where a relative refractive index difference Δat an outermost interface is smaller than a relative refractive index difference Δat an innermost interface.
