Abstract

PURPOSE: To obtain an optical fiber which prevents leakage light at broken parts as far as possible and is capable of positively searching the broken parts by forming an optical guide layer of a relatively high refractive index on the outside circumference of clad layer and providing a protecting layer on its outside circumference.
