Abstract
All plastic optical fiber (APF) has been usually applied in the field of short distance optical signal transmission. However, heat-resistance of commercial APFs is so low that their application has been limited. In this paper, core of APF was made from crosslinked polymer. In order to make clear the controll factors of APF's properties, fabricating condition, crosslinking density and others were studied. As a result, the heat resistance for optical fiber is relate with the deformation during heating. Drawn fibers are deformed by heating and their light tansmittances are reduced by deformation. On the other hand, undrawn and crosslinked core fiber shows excellent heat resistance, because it has never been elongated in fabricating process. And the developed fiber has the desirable mechanical characteristics, along with chemical durability.
