Abstract
The present disclosure relates to an optical fiber or the like that can be adapted to an optical transceiver for a short wavelength band of 850 nm or more and 1060 nm or less while maintaining compatibility with an SMF of the related art. An optical fiber of one embodiment includes a core, a cladding, and a resin coating, and has a mode field diameter of 8.2 µm or more and 9.6 µm or less at a wavelength of 1310 nm, a cable cutoff wavelength of an LP11 mode of 1060 nm or more and 1260 nm or less, and a cable cutoff wavelength of an LP02 mode of 1060 nm or less.

An optical fiber comprising:
- a core extending along a fiber axis and comprised of silica glass;
- a cladding provided on an outer peripheral surface of the core, comprised of silica glass, and having a maximum refractive index lower than a maximum refractive index of the core;
- and
- a resin coating provided on an outer peripheral surface of the cladding, wherein
- the optical fiber has a mode field diameter of 8.2 µm or more and 9.6 µm or less at a wavelength of 1310 nm, a cable cutoff wavelength of an LP11 mode of 1060 nm or more and 1260 nm or less, and a cable cutoff wavelength of an LP02 mode of 1060 nm or less.
An optical cable comprising:
- a plurality of optical fibers;
- and
- a sheath that surrounds the plurality of optical fibers,
- wherein each of at least two optical fibers of the plurality of optical fibers includes a core extending along a fiber axis and comprised of silica glass, a cladding provided on an outer peripheral surface of the core, comprised of silica glass, and having a maximum refractive index lower than a maximum refractive index of the core, and a resin coating provided on an outer peripheral surface of the cladding, and
- the optical cable has a mode field diameter of 8.2 µm or more and 9.6 µm or less at a wavelength of 1310 nm, a cable cutoff wavelength of an LP11 mode of 1060 nm or more and 1260 nm or less, and a cable cutoff wavelength of an LP02 mode of 1060 nm or less.
