An optical transmission member, a connecting section structure of the optical transmission medium and optical device, method for manufacturing an optical transmission medium

摘要

The optical transmission body by long-cherished desire invention is something which features that the above-mentioned amorphous core material at least has designated polymer poly- all and the polymer which consists of the hydroxy basic reactivity multifunctional compounds as the constitution component in the optical transmission body which consists of with the amorphous core material whose refractive index is higher than the tube condition clad material and the said tube condition clad material.
