METHOD FOR MANUFACTURING MULTI-CORE OPTICAL FIBER AND METHOD FOR MANUFACTURING MULTI-CORE OPTICAL-FIBER CONNECTOR

摘要

The present invention makes it possible to manufacture a multi-core optical fiber with precisely positioned cores even if the preform itself is large. A preform is obtained by using an alignment fixation member to fix a plurality of rod-shaped core members in place with the relative positional relationships therebetween fixed and integrating the core members into a cladding material. The obtained preform is then drawn to produce a multi-core fiber with precisely controlled core positions.
