ABSTRACT:
The terminal treatment device for a plastic optical fiber is improved so that void formation between the melt zone of the ferrule and the plastic optical fiber is avoided, leading to the prevention of crack formation. The device constitutes a chamber, the upper side of which is open, a heater in the chamber, a heated element which may be at the top of the chamber, and a base frame and a top frame to secure the heated element to the chamber. The element is a rectangular plate, made of a metal having good thermal conductivity and includes a thicker part and a thinner part surrounding it. At the center of the thicker part, there is provided a blind hole into which the tip of the ferrule is fitted. A plurality of heat evacuation vents is formed around this blind hole and elsewhere in the chamber to facilitate cooling.
