How to Cut Fiber Optic Cables How to Cut Fiber Optic Cables

What You'll Need
Wire strippers
Wire cutters
Protective gloves
A very sharp knife
Metal scissors

If you've recently had cause to cut fiber optic cables, you may be curious about the proper method of cutting. If so, you'll be pleased to know that with the right set of tools, fiber optic cable cutting can be a very simple undertaking. Read on to learn the basics of cutting fiber optic cables.

Step 1 - Remove the Wire Jacket

Begin by donning a pair of protective gloves, which you will wear for the full duration of this job. Next, use your knife or wire strippers to cut into the cable's outer jacket. After making an incision, peel away the fiber optic cable's protective jacket.

Step 2 - Cut the Kevlar Fibers

Having removed the fiber optic cable's outer jacket, you should now see glass fiber tubing, several coated wires and a number of exposed Kevlar fibers. You'll now need to twist the Kevlar fibers, causing them to form a strand the resembles a rope. Once the fibers have been sufficiently twisted, use your metal scissors to trim them.

Step 3 - Bend the Glass Tubing

Now that you've trimmed the Kevlar fibers, use your knife to make a small scratch across the point in the glass tubing at which you intend to make your cut. Using your fingers, slightly bend the glass tubing at the point you just marked. As glass tubing is not particularly resilient, this should cause it to cleanly break.

Step 4 - Apply Your Finishing Touches

Having bent your glass tubing, use your wire cutters to trim the rest of the wires accordingly.
