Claims
- 1. An optical connector comprising a ferrule including an optical fiber,wherein a hollow portion is formed on a front end face of said ferrule, an optical fiber protrusion port, from which a tip face of said optical fiber is protruded into said hollow portion, is formed on a bottom face of said hollow portion, and said tip face of said optical fiber retreats to be led in by 5 to 10 μm with respect to said front end face of said ferrule, and wherein said hollow portion is filled with a grease-like refractive index matching material, and said tip face of said optical fiber is completely drawn in said grease-like refractive index matching material.
- 2. The optical connector according to claim 1, wherein said hollow portion has a rectangular opening window.
- 3. The optical connector according to claim 1, wherein said hollow portion is formed into a slit-shape.
- 4. The optical connector according to claim 1, wherein said hollow portion has a depth of 20 μm or more.
- 5. The optical connector according to claim 1, wherein plural optical fiber protrusion ports are provided on the bottom face of said hollow portion corresponding to the number of said optical fibers.
- 6. A method of assembling an optical connector comprising a ferrule including an optical fiber, the method comprising the steps of:applying a grease-like refractive index matching material so that said grease-like refractive index matching material enters a hollow portion which is formed on a front end face of said ferrule; inserting said optical fiber so that a tip face of said optical fiber is protruded from an optical fiber protrusion port, which is formed on a bottom face of said hollow portion, into said hollow portion and said tip face of said optical fiber is completely drawn in said grease-like refractive index matching material; and fixing said optical fiber to said ferrule.
- 7. The method according to claim 6 including:before the step of inserting said optical fiber, pressing a ferrule abutment face of an optical fiber press member against said front end face of said ferrule with a positioning protrusive portion of said optical fiber press member entering said hollow portion, said positioning protrusive portion is provided with a flat optical fiber press face which is protruded from said ferrule abutment face by 5 to 10 μm; the step of inserting said optical fiber including inserting said optical fiber so that a tip face of said optical fiber abuts on said optical fiber press face; and after the step of fixing said optical fiber to said ferrule, removing said optical fiber press member from said ferrule.
- 8. The method according to claim 6, wherein the tip face of said optical fiber is subjected to an edge removal treatment by an electron discharge machining.
- 9. The method according to claim 6, wherein the tip face of said optical fiber is subjected to an edge removal treatment by polishing.
