SYSTEM FOR REMOVING COATING LAYERS FROM OPTICAL FIBER INCLUDING OUTER COATING LAYER HAVING HEAT DEFLECTION TEMPERATURE HIGHER THAN HEAT DEFLECTION TEMPERATURE OF INNER COATING LAYER AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A system for removing coating layers from an optical fiber including an outer coating layer having a heat deflection temperature higher than a heat deflection temperature of an inner coating layer and a controlling method thereof are provided to remove easily the coating layers from the optical fiber having plural coating layers by using a non-contact method. CONSTITUTION: A housing is used for forming a sealing space in a coating layer removal process. A heating unit(32,34,36) generates heat to remove a coating layer of an optical fiber. A temperature sensor(40) is used for sensing a temperature of the heating unit. A blower(22) is used for transferring the generated heat to the optical fiber. A transfer unit inserts the optical fiber into the inside of the housing and draws the optical fiber without the coating layer from the housing. A control unit(100) controls a driving point of the blower, controls a heating state of the heating unit according to a sensed temperature, and controls an elevating operation of the transfer unit. A power supply(80) is used for supplying the power to the heating unit, the blower, the transfer unit, and the control unit.
