The hot plate process is one of a number of processes used in the fabrication and surface finishing of polymer fibers
. Others are based on polishing the broken face or cutting , the press-cut process, the polymer fiber. Hote plate is a thermal process in which the face of the polymer fiber is smoothed with heat. During termination, the sheath of the polymer fiber is removed in a short area. During connector assembly, the polymer fiber is pushed through the ferrule until a few inches of polymer fiber protrude from the ferrule. The polymer fiber is then cut so that it has an overhang, and the surface is pressed against a hot mirror. After cooling, the POF connector is assembled.
