Abstract:
An optical fiber includes a core having a maximum refractive index n 1 , and cladding provided around the core and having a refractive index n 0  that is lower than the maximum refractive index n 1 . A radial refractive-index profile of the core is expressed with an exponent a that is 1.5 to 10. A relative refractive-index difference Δ 1  at a center of the core that is expressed as Δ 1 =100×(n 1 2 −n 0 2 )/(2n 1 2 ) is 0.3% to 0.5%. A diameter 2a of the core is 9 μm to 14 μm. A zero-dispersion wavelength is 1300 nm to 1324 nm. A cable cutoff wavelength λcc is 1260 nm or shorter. A bending loss at a wavelength of 1550 nm in a case where the optical fiber is wound by ten turns with a bend diameter of 30 mm is 0.25 dB or smaller.

Claim (Index 1):
An optical fiber comprising:\n a core having a diameter 2a of 9 \u03bcm to 14 \u03bcm; a maximum refractive index n 1 ; and a radial refractive-index profile expressed with an exponent \u03b1 of 1.5 to 10; and a cladding provided around the core and having a refractive index n 0  that is lower than the maximum refractive index n 1 ; and a depressed portion provided around the core and between the core and the cladding and having a refractive index n 2  that is lower than both the maximum refractive index n 1  and the refractive index n 0 , wherein a relative refractive-index difference \u0394 1  at a center of the core that is expressed as \u0394 1 =100\u00d7(n 1 2 \u2212n 0 2 )/(2n 1 2 ) is 0.3% to 0.5%, and a relative refractive-index difference \u0394 2  of the depressed portion that is expressed as \u0394 2 =100\u00d7(n 2 2 \u2212n 0 2 )/(2n 2 2 ) is \u22120.1% to 0% and wherein the optical fiber has a zero-dispersion wavelength of 1300 nm or longer and 1324 nm or shorter, a cable cutoff wavelength \u03bbcc of 1260 nm or shorter, and a bending loss at a wavelength of 1550 nm of 0.25 dB or smaller in a case where the optical fiber is wound by ten turns with a bend diameter of 30 mm.
