Abstract

PURPOSE:To prevent an optical fiber element from breking down at a high temperature by hardening at least both terminal parts of the optical fiber element with synthetic resin whose hardness is high at the normal temperature and decreases as the temperature rises. CONSTITUTION:At least both terminal parts of a bundle 13 of many optical fiber elements 12 are hardened with synthetic resin (e.g. nylon) 15 whose hardness is relatively high at the normal temperature and decreases at high temperature (80- 150 deg.C). Consequently, cracking in polishing each terminal surface of the optical fiber bundle is prevented to obtain a superior polished surface. Then, optical transfer effect is secured and even at high temperature, an increase in the volume of the optical fiber element due to their expansion is absorbed by the synthetic resin, preventing the elements from breaking down.
