titleOfInvention A process of preparing for the graded-index typed plastic optical fiber
abstract The present invention relates to a method of manufacturing a plastic optical fiber having a continuous refractive index distribution, a resin is mixed with a dopant (non-reactive material) in a melt extruder (Extruder) and then melt spinning and stretching them to prepare a fiber In addition, the prepared fibers are passed through the monomer solution or the monomer melt of the resin polymer to extract dopants present in the fiber cross-section outer layer. In the present invention, polymethyl methacrylate (PMMA) or the like is used as the resin polymer, bromo benzene or the like is used as the dopant, methyl methacrylate (MMA) or the like is used as the monomer of the resin polymer. The present invention can produce a graded index-type plastic optical fiber having a low distortion rate of an optical signal and a large transmission band in a simplified continuous process.
