Abstract:
An optical fiber includes a core, a depressed layer surrounding the core, and a cladding surrounding the depressed layer, where a refractive index profile of the core is an α power distribution in which an index α is 3 or more and 6 or less, a relative refractive index difference Δ −  of the depressed layer with respect to the adding is set such that an absolute value |Δ − | thereof is 0.01% or more and 0.05% or less, a radius r1 of the core and an outer circumference radius r2 of the depressed layer are set such that a ratio r1/r2 thereof is 0.2 or more and 0.5 or less, a cable cutoff wavelength λ cc  of 22 m is 1260 nm or less, and a mode field diameter MFD at a wavelength of 1310 nm is 8.6 μm or more and 9.5 μm or less.

Claim (Index 3):
The optical fiber according to  claim 1 , wherein\n the radius r1 and the outer circumference radius r2 are set such that the ratio r1/r2 thereof is 0.25 or more and 0.45 or less.
