A fiber optic ferrule is disclosed which utilizes three spheres that define a tricuspid interstitial space therebetween into which the end of an optical fiber is mounted. A collar is threadedly mounted on the forward end of the ferrule body. The collar embodies an inwardly extending lip which urges the spheres radially inwardly when the collar is threaded onto the body. A sleeve is threadedly mounted on the rear of the body. To terminate the ferrule to a fiber optic cable, the fiber of the cable is first inserted through the ferrule body into the interstitial space forwardly beyond the spheres. The sleeve is crimped onto the jacket of the cable. By the use of appropriate indicia on the sleeve and the ferrule body, the sleeve is located at a predetermined position axially on the body. Tension is applied to the fiber. Then the collar is threaded onto the body to contract the spheres inwardly and cleave the fiber at the tangency point of the spheres. The sleeve is then rotated to a second position, indicated by second indicia on the ferrule body, thus advancing the fiber to the appropriate position in the interstitial space for abutting the fiber in a mating ferrule.
