Abstract
A cavity-preventing type reactor and a method for fabricating a preform for a plastic optical fiber using the same, wherein post-process charging of additional monomer or prepolymer into rotationally-induced central cavities is avoided by forming void-free plastic fibers using special geometric flow controllers combined with special materials combinations, pressures, and rotational techniques.
