摘要：The present invention relates to an optical fiber having a sufficient strength, inwhich not only a core region but also a cladding region contains GeO, and an optical

component including the same. The optical fiber has an outer diameter D; and comprisesa core region, a first cladding region surrounding the core region, and a second claddingregion surrounding the first cladding region. The core region is a glass region mainlycomposed of a silica glass material with a GeOcontent of 1 wt % or more. The firstcladding region is a glass region, mainly composed of a silica glass material with aGeOcontent of 1 wt % or more, having an outer diameter of 0.80D or more but 0.98D orless. The second cladding region is a glass region mainly composed of a silica glassmaterial with a GeOcontent of less than 0.2 wt %.
