Method for coupling plastic optical fibers

摘要

A method for coupling plastic optical fibers (8,9) and a plastic optical fiber unit coupler are provided by providing a lower holder (1), which includes a groove (2) for holding plastic optical fibers in a longitudinal direction; and abutting and coupling opposed end faces of the plastic optical fibers together while causing the holder to apply a lateral pressure to the plastic optical fibers therein to sandwich the plastic optical fibers. <IMAGE>
