PURPOSE:To perform terminal processing simply and quickly by hardening the filler at the terminal of pipe covered optical fiber by bringing the filler into reaction with a hardening agent. CONSTITUTION:The filler 4 of pipe covered optical fiber 1 consists of a base in two-liquid type RTV silicone rubber which is hardened by heating or at normal temperature. When processing the terminal 1' of the pipe covered optical fiber 1, a specified quantity of hardening agent 6 is injected from the end face of the pipe covered optical fiber 1 or from its outer periphery or from these two places into the tublar cover layer through an injector 5, and the filler 4 is hardened by bringing it into reaction with the hardening agent 6. When a hardened part 7 is formed at the terminal 1' of the pipe covered optical fiber 1, flowing-out of the filler 4 is suppressed by stopping effect of the hardened part 7. |
