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

A heat treatment apparatus for an optical fiber reinforcing member capable of setting an optimal heating condition in accordance with a voltage applied to a heater is provided. The heat treatment apparatus (10) of the optical fiber reinforcing member includes a fiber holding portion (11) capable of holding the optical fiber covered with the reinforcing member, a heater (12) capable of heating the reinforcing member, And a control unit 20 for controlling the application of a voltage from the power supply unit 14 to the heater 12. [ The control unit 20 includes a detecting unit 21 for detecting a parameter for obtaining a calorific value of the heater 12, a storage unit 22 for storing a plurality of different heating conditions for each parameter value, And a condition designating section 23 for designating any one of a plurality of heating conditions mutually according to the value of the parameter and instructing the power supply section 14 to apply a voltage to the heater 12 based on the selected heating condition.
