Apparatus for manufacturing plastic optical fiber and method for manufacturing plastic optical fiber

Abstract

The present invention provides an apparatus for manufacturing a plastic optical fiber suitable for adjusting a plastic optical fiber to be uniform in size while inhibiting the entry of a metal that causes an increase in transmission loss of the plastic optical fiber. The apparatus for manufacturing a plastic optical fiber of the present invention is provided with an extruding device and a gear pump. The extruding device has a containing portion that contains a resin composition, and introduces a gas into the containing portion to extrude the resin composition from the containing portion by means of the gas. The gear pump adjusts a flow rate of the resin composition extruded from the extruding device.
