Abstract
A ferrule has a cylindrical body constructed from a single piece of material and having an outer circumferential surface. A first insertion hole of the cylindrical body is bounded by a first inner surface of the cylindrical body and is configured to receive therein a first preselected portion of an optical fiber so that the first preselected portion of the optical fiber is in direct contact with the first inner surface of the cylindrical body. A second insertion hole of the cylindrical body is disposed in communication with the first insertion hole. The second insertion hole is bounded by a second inner surface of the cylindrical body and is configured to receive therein a second preselected portion of the optical fiber enclosed in a buffer coating so that the second preselected portion of the optical fiber is in direct contact with the second inner surface of the cylindrical body. A flange member separate and independent from the cylindrical body is connected directly to the outer circumferential surface of the cylindrical body.
