Abstract

PURPOSE: To improve heat resistance by filling a refrigerant such as water or oil into a metal pipe housing an optical fiber core, optical fiber cord or optical fiber cable and circulating this.
CONSTITUTION: A refrigerant 9 such as water or noncombustible oil is filled in a pipe 8 of aluminum or iron housing an optical fiber core, optical fiber cord or optical fiber cable 4, and is circulated by a pump 10. Thereby, the heat resistance may be improved.
