The Newport FK12 is an electronic angled fiber cleaver engineered to produce high-quality fiber ends with user-selectable cleave angles from 0° to 15°. It employs patented ultrasonic cleaving action with a precision ground diamond blade to achieve mirror-like fiber surfaces while minimizing back reflections to levels below −60 dB. This approach eliminates the complexity and time requirements of traditional angle polishing or index matching methods, delivering simple, fast, and repeatable cleaving performance suitable for sensitive fiber optic systems.
