FK12 Precision Fiber Optic Cleavers
Lab-grade fiber optic cleaver using ultrasonic cleaving technology with selectable cleave angle 0–15° for high-return-loss terminations.
Overview
The FK11 and FK12 fiber optic cleavers both use ultrasonic cleaving technology to produce flat, defect-free end-faces. The standard FK11 is designed for cleaving standard telecom fibers in preparation for fusion splicing and testing, with variants for large-diameter cladding (FK11-LDF), small-diameter fibers (FK11-SDF / USDF) and coated cleaving (FK11-C). The FK12 cleaver produces similarly low cleave angles to the FK11, but its primary application is creating cleaves with a user-selectable end angle for low-reflectance terminations.
