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.
Claims6
An optical fiber composite ferrule comprising:
- a ferrule base section which allows an optical fiber to be inserted, the ferrule base section including a leading terminal section made of a metallic alloy containing zirconia and having an optical fiber wire insertion bore, and a trailing terminal section made of a synthetic resin having a linear expansion coefficient equal to or less than that of the leading terminal section;
- and
- a flange section formed at one end of the trailing terminal section of the ferrule base section,
- wherein the synthetic resin is made of polybutylene terephthalate containing a carbon fibrous filler in a volume range between 20 and 50%.
