Fiber Optic Cleavers Information

Fiber Optic Cleaver from Fusion SplicersFiber optic cleavers are cutting tools that make optical fiber end face cuts. Applications for fiber optic cleavers include networking and telecommunications. They are often used with Fiber Optic Cables, Fiber Optic Connectors, and Fiber Optic Splicers.

The primary function of a fiber optic cleaver is to precisely cut optical fiber. These tools are relied on to cut the fiber as smoothly as possible to reduce loss of signal. If the cut of the fiber is not a clean perpendicular cut then the rough surfaces results in optical return loss from the scattering or reflection of light.

Types of Fiber Optic Cleavers

There are multiple types and configurations of fiber optic cleavers.

  • Electronic Cleavers use a blade that is attached to a resonant acoustic horn and is automatically moved to the fiber.
  • Manual Cleavers use a fixed blade that is manually moved to the fiber.
  • Handheld / Pocket Cleavers are small handheld cleavers or pen-shaped scribes used for in the field and low volume cleaves applications.
  • Desktop Cleavers are precision cleavers that can cleave single fibers or ribbon fibers and handle high volumes of cleaves.


Fiber Optic Cleaver from TessoThe following specifications determine the functionality of a fiber optic cleaver.

  • Cleave angle is the angle which the cleaver cuts the optical fiber.
  • Number of cleaves is the number of cleaves the blade can make before replacement is needed.


These features provide additional utility or ease-of-use.

  • Built-in fiber scrap collector
  • Automatic blade rotation
