Can You Cut Fiber Optic Light Cable?

Yes, it is possible to cut fiber optic light cables, a process that is often necessary for installation, repairs, or customization of fiber optic networks. However, cutting fiber optic cables requires precision and the right tools to ensure the integrity of the optical fibers and maintain signal quality. Below are detailed steps and considerations involved in cutting fiber optic cables.

Tools Required

  • Fiber optic cleaver
  • Fiber optic stripper
  • Isopropyl alcohol and wipes

Steps for Cutting Fiber Optic Cables

  1. Preparation: Begin by carefully removing the outer jacket of the cable using a fiber optic stripper, exposing the fragile optical fibers inside.
  2. Cleaning: Clean the exposed fiber using wipes soaked in isopropyl alcohol to remove any debris or contaminants.
  3. Cleaving: Use a fiber optic cleaver to make a precise, clean cut on the fiber. The cleaver applies a precise amount of pressure to create a smooth, flat end face that is perpendicular to the fiber axis.


  • Quality of Tools: The quality of the cleaver and stripper is crucial for a clean cut and to avoid damaging the fibers.
  • Safety: Fiber shards are extremely sharp and can cause injury or damage. Proper disposal and handling are essential.
  • Training: Proper training or experience is recommended to ensure the cut is made correctly and to avoid costly mistakes.

After cutting, the fiber optic cable is typically ready for further steps such as splicing or connectorization, depending on the application. It's important to note that while cutting fiber optic cables is a common practice, it requires precision and care to maintain the performance and reliability of the fiber optic network.
