  • Optical fiber composite ferrule
    Patent number: 7118289
    Abstract: An optical fiber composite ferrule 1 is disclosed as having a leading terminal member 1A made of hard material such as zirconia ceramic, and a trailing terminal member 2A made of synthetic resin having a linear expansion coefficient equal to or less than that of the leading terminal member 1A. By so forming, a stress to be imparted to an optical fiber due to surrounding temperature variation can be lessened.
