PURPOSE:To prevent an optical fiber from corroding, to radiate heat efficiently, and to prevent the optical fiber from damaging by forming a thin film of a heat- resistant polymer or gold where a fixation part for supporting the optical fiber fixedly contacts the optical fiber. CONSTITUTION:The optical fiber 1 is made of halide crystal and the 1st layer 4 of the thin film of the heat-resistant polymer, such as fluororesin, polyimide, and polyamide, or gold is formed where the optical fiber fixation part contacts the optical fiber 1 directly. The 2nd layer 5 of Al, etc., and a protecting tube 2 are provided thereupon. Consequently, the corrosion of the optical fiber is prevented, the heat generated during optical transmission is radiated efficiently, and the damage of the optical fiber 1 by the optical fiber fixation part is prevented. |
