摘要
A silica-based multi core optical fiber and a fabrication method for the same are provided, and include two or more cores of GeO2-SiO2 glass including a fluorine concentration between 0,05 and 2 wt% and a germanium concentration of not less than 15 wt%, in a core. A relative refractive index difference of a cladding and a core is not less than about 3%; and a ratio of a cladding diameter to a core diameter is about 1.02 to 3.0. A silica-based single core optical fiber is also provided, and includes a core having a germanium concentration not less than about 15 wt% and a fluorine concentration about 0.05 wt% to 2 wt%.
