The FK11 cleaver is for fibers with nominal coating diameters of 250µm, and clamps fiber 16mm from cleave point.

The FK11 Precision Fiber Cleaver from Photon Kinetics uses patented, ultrasonic cleaving technology to produce flat, clean, low end-angle cleaves every time. That means low-loss, high-strength fusion splices, optimum performance of pigtailed active devices, and consistent results in measurement applications. The FK11 will also minimize  the time required to make splices and maximize the output of test systems that rely on high-quality cleaves.

FK11 Fiber Optic Cleavers employ an ultrasonic cleaving technology to produce flat, defect-free fiber end-faces. The standard FK11 is designed for cleaving standard telecom fibers in preparation for fusion splicing and fiber testing. Variants of the FK11 include the FK11-LDF for larger cladding diameter fibers, the FK11-SDF and FK11-USDF for small diameter fibers and the FK11-C for cleaving through the fiber coating.

  • Tensions fiber prior to cleaving prevents damage to end face.
  • Low end angle for low loss splicing (FK11).
  • Long-life durable diamond blade provides extended use.
  • Variants for cleaving a variety of fiber diameters, and through fiber coatings.
  • Easy to use.
