The FK11 & FK12 Fiber Optic Cleavers are simply the best cleavers in the world. Using an ultrasonic cleaving method, the cleavers provide accurate cleaves of fibers in preparation for fusion splicing or termination. With a wide variety of fiber diameters and types, the FK11 series meets every cleaving application. Whether fusion splicing in the field or connectorizing in the lab, the FK series cleaves are fast and easy to use. The accuracy enhances system and component performance and maximizes efficiency by eliminating the need to continuously re-cleave fibers to obtain the desired results. Additionally, the FK12 cleaver allows the user to cleave the fiber from 0º to 15º for specific applications where a low reflectance is required, such as the industry standard 8º angled polish.
