Fujikura CT-04 SM MM High Precision Fiber Cleaver

The Fujikura CT-04 is a high-precision fiber cleaver designed for both single-mode and multimode conventional silica optical fibers. It delivers consistent cleaves essential for low-loss connections in field and laboratory environments. The instrument accommodates fiber counts from 2 to 12 fibers using interchangeable adapter plates, with dual V-groove geometry supporting both 250 µm and 900 µm coating diameters over 125 µm bare fiber. Cleaving angle averages 0.8° (0.5° for single fiber), ensuring minimal splice loss and junction degradation.
