HEAT TREATMENT DEVICE FOR OPTICAL FIBER REINFORCING MEMBER OPTICAL FIBER FUSION SPLICER PROVIDED WITH SAME HEAT TREATMENT DEVICE AND METHOD FOR HEAT TREATING OPTICAL FIBER REINFORCING MEMBER

摘要

Provided is a heat treatment device for an optical fiber reinforcing member capable of setting optimal heating conditions according to a voltage applied to a heater. The heat treatment apparatus 10 of the optical fiber reinforcing member includes a fiber holding portion 11 capable of holding an optical fiber covered with a reinforcing member and a heater 12 capable of heating the reinforcing member, and a voltage to the heater 12. It is provided with a power supply unit 14 for applying a power supply, and a control unit 20 for controlling voltage application from the power supply unit 14 to the heater 12. The control unit 20 is detected by a detection unit 21 that detects a parameter for obtaining a heating value of the heater 12, a storage unit 22 that stores a plurality of different heating conditions for each parameter value, and a detection unit 21 A condition indicator 23 is provided to select any one of a plurality of heating conditions from each other according to the value of the selected parameter and instruct the power supply unit 14 to apply a voltage to the heater 12 based on the selected heating condition.
