본 개시는, 코어 및 클래드를 포함하는 유리 섬유와, 유리 섬유에 접하여 해당 유리 섬유를 피복하는 프라이머리 수지층과, 프라이머리 수지층을 피복하는 세컨더리 수지층을 구비하고, 세컨더리 수지층이, 유레테인 (메트)아크릴레이트 올리고머, 모노머 및 광중합 개시제를 함유하는 베이스 수지와, 무기 산화물 입자를 포함하는 수지 조성물의 경화물로 이루어지고, X선 소각 산란법으로 측정되는 무기 산화물 입자의 체적 평균 입경이 800nm 이하이고 또한 체적 평균 입경의 규격화 분산이 60% 이하인, 광섬유에 관한 것이다. The present disclosure relates to an optical fiber comprising a glass fiber including a core and a clad; a primary resin layer that coats the glass fiber by being in contact with the glass fiber; and a secondary resin layer that coats the primary resin layer, in which the secondary resin layer is formed from a cured product of a resin composition that includes a base resin containing a urethane (meth)acrylate oligomer, a monomer, and a photopolymerization initiator; and inorganic oxide particles, a volume average particle size of the inorganic oxide particles as measured by a small angle X-ray scattering method is 800 nm or less, and a standardized dispersion of the volume average particle size is 60% or less.
