OPTICAL FIBER COMPONENT, OPTICAL MODULE, AND OPTICAL COMMUNICATION SYSTEM

摘要

This invention provides an optical fiber component or the like having a structure with a high degree of freedom in design as an intermediate member for optically connecting optical functional components having different MFDs without increasing a connection loss. The optical fiber component includes an optical fiber having two end faces polished. The optical fiber has the first MFD conversion portion for changing the mode field diameter at an end portion including one end face, and the second MFD conversion portion for changing the mode field diameter at an end portion including the other end face opposing one end face.
