Abstract
Provided is an extreme bending insensitive optical fiber. The optical fiber includes a core comprising a maximum refractive index difference Δn1 in the optical fiber, an inner layer comprising a refractive index difference Δn2 that is smaller than the maximum refractive index of the core and decreases in a direction away from the core, the inner layer being positioned outside the core, and a trench layer comprising an inner-circumference refractive index difference Δn3 that is smaller than the refractive index difference of the inner layer and an outer-circumference refractive index difference Δn4 that is a minimum refractive index difference in the optical fiber.
