Abstract
A reinforced optical fiber includes a reinforcing inner layer interposed between a buffer layer of silicon rubber and a FRP layer made of styrene resin and fibers. The reinforcing inner layer is formed by binding filaments attached longitudinally onto the buffer layer with a non-styrene resin. The additional reinforcing inner layer improves crushing resistance and also keeps low an increase of transmission loss. The reinforcing inner layer directly covering the buffer layer is formed by the steps of longitudinally attaching dry filaments to the buffer layer and then impregnating the filaments with a curable resin.
