  • Connector component for optical fiber, manufacturing method thereof and optical member
    Patent number: 8202010
    Abstract: A connector component for optical fibers has good dimensional accuracy and parallelism. The connector component includes a base material. The base material is provided with at least two holes for inserting and fixing optical fibers therein. The base material is made of quartz glass. Inner components are arranged for forming holes for inserting optical fibers in a die for forming an outer form of the connector component with a dimensional accuracy equal to or less than 2 ?m. Slurry is poured into the die, the slurry including quartz powder, a resin binder, a dispersant, water and a curing agent. The poured slurry is cured and heated under vacuum so as to vitrify the cured slurry to obtain the quartz glass.
