Abstract

An optical fiber connection structure includes: a tubular member; a first collimator attached to a first end of the tubular member in an axial direction; and a second collimator attached to a second end of the tubular member. The first collimator includes a first optical fiber, a first ferrule, a first lens, and a first sleeve. The second collimator includes a second optical fiber, a second ferrule terminating the second optical fiber, a second lens, and a second sleeve. The first sleeve is fixed to the first end via adhesive in a state where the first lens faces the tubular member, and the second sleeve is fixed to the second end via adhesive in a state where the second lens faces the tubular member. An outer diameter of the second ferrule is larger than that of the second lens.
