Abstract
A process for polishing the end face of a gigabit plastic optical fiber (GbPOF) to produce a mirror smooth surface without any defect. Smooth GbPOF end faces reduce the optical coupling loss when two plastic optical fibers are connected. The polishing process can be used to produce GbPOF end faces which are free of defects such as scratches. The polishing process involves the use of successive abrasive films having decreasing surface roughness to abrade the end of a GbPOF. More specifically, each subsequently applied abrasive film has a mean particle size which is less than the mean particle size of the previously applied abrasive film.
