Abstract
A ferrule for an optical fiber connector has a cylindrical sleeve or body (1) and a capillary (3) received in the sleeve 1. The sleeve (1) has thereinside a fiber holding portion (2a) adjoining one end of the sleeve (1) and for holding a built-in optical fiber (4), a capillary holding portion (2b) next to the fiber holding portion (2a), and a fiber inserting portion (2c) next to the capillary holding portion (2b) and for inserting an optical fiber (6). The fiber holding portion (2a) and the fiber inserting portion (2c) have the smallest diameter and the largest diameter, respectively. The diameter of the capillary holding portion (2b) is substantially equal to the outside diameter of the capillary 3. The axis of the fiber holding portion (2a) is accurately coincident with the axis of the sleeve (1). The capillary (3) is held in the capillary holding portion (2b) while the fiber (4) extends over the fiber holding portion (2a) and a through bore formed in the capillary 3. A through notch (5) is formed in the capillary (3) and filled with a refractive index matching material (7).
