Pulling terminal structure, pulling-end-equipped optical cable, and method for manufacturing pulling-end-equipped optical cable

A connector system includes: a first ferrule configured to hold end parts of multi-core fibers; a second ferrule configured to hold end parts of single-core fibers; and an optical connection member. The optical connection member is arranged between the first and the second ferrule, and includes an optical system configured to optically connect respective cores included in the multi-core fibers and the single-core fibers. A guide pin is formed on one of the first and the second ferrule, and a guide hole is formed in another of the first and the second ferrule. A through hole is formed in the optical connection member, and the first ferrule, the optical connection member, and the second ferrule can be aligned by fitting the guide pin in the guide hole through the through hole.
