摘要： A connector for a high energy beam, which is provided with a sleeve fitted on an optical fiber and having an optical fiber support portion of an inner diameter about equal to a diameter of the optical fiber and a larger diameter portion positioned ahead of the optical fiber support portion and having an inner diameter larger than the diameter of the optical fiber so as to form a gap around the optical fiber and in a proper length from the end face of the optical fiber. The optical fiber support portion is formed of a heat resistant inorganic substance having a melting point of 1500.degree. C. or more, for example, a transparent substance, such as sapphire, or an opaque substance, such as aluminium oxide; the so-called fine ceramics. The connector of the present invention is free from burning, melting and diffusion of metallic material, and breakage of optical fiber when in use, thereby being easy to handle and high in quality and reliability and having a long life time.

摘要： The present invention relates to a connector for connecting optical fiber ribbons to each other, each of ribbons including a plurality of optical fibers spaced in line, and a method of attaching the same. The connector comprises an alignment member for placing the optical fibers in the grooves formed therein, a deformable metal member disposed on the optical fibers in the grooves of the alignment member, and a ferrule incorporated at the front end pportion with both the alignment member and the deformable metal member and adapted at the rear end portion to retain the unexposed portion of the optical fiber ribbon. Accordingly, the optical fibers are fixedly held between the alignment member and the deformable metal member while the ribbon is fixedly held by the rear end portion of the ferrule. The front ends of the optical fibers are cut at the front end of the ferrule. As the result, the optical fiber ribbon can remain fastened firmly and securely for a long period of time and additionally, its attaching work can be made with ease within a short time.
