The invention discloses a temperature matching optical fiber and a preparation method thereof. The temperature matching optical fiber is characterized in that the cross section structure of the optical fiber sequentially comprises a fiber core (1), a cladding (2), an inner coating (3) and an outer coating (4) from the center to the outside. The fiber core and the cladding are made of multi-component glass, and the inner coating and the outer coating are made of acrylic resin materials. Wherein the fiber core glass component comprises the following components in percentage by weight: 68% to 78% of SiO2, 3.9% to 5.9% of B2O3, 14.5% to 24.5% of GeO2, 1% to 3% of P2O5, 0.1% to 0.3% of Al2O3, 0.2% to 0.4% of CaO, 0.2% to 0.4% of MgO and 0.1% to 0.2% of Na2O; and the cladding glass comprises the following components in percentage by weight: 69 to 79 percent of SiO2, 19 to 23 percent of B2O3, 1.9 to 2.3 percent of GeO2, 1 to 3 percent of P2O5, 0.1 to 0.3 percent of Al2O3, 0.1 to 0.3 percent of CaO, 0.1 to 0.3 percen
