Cutting fiber optic cable requires precision to avoid damaging the delicate glass fibers. Use a specialized fiber optic cable cutter to ensure a clean break, removing any damaged section to allow for a proper splice or termination.
Here's a more detailed breakdown:
-
Use the Right Tool: Avoid using regular wire cutters or scissors. These can crush or shatter the glass fibers within the cable. Instead, use a dedicated fiber optic cable cutter designed for this purpose. These tools are specifically designed to score and cleave the cable cleanly.
-
Identify the Damaged Section: Before cutting, visually inspect the cable for any visible damage, such as kinks, breaks, or crushed areas. You need to cut beyond this point to ensure a clean, undamaged end.
-
Prepare the Cable: Clean the cable section you plan to cut. Use a lint-free wipe and isopropyl alcohol to remove any dirt, dust, or grease. This ensures a clean cut and prevents contamination.
-
Make the Cut: Place the cable in the fiber optic cutter according to the manufacturer's instructions. Ensure the cable is properly aligned. Apply a firm and even pressure to cleave the cable. The goal is to create a straight, clean cut, perpendicular to the axis of the cable.
-
Inspect the Cut: Visually inspect the cut end of the cable with a magnifying glass. The surface should be smooth and free of cracks or chips. If the cut is uneven or damaged, recut the cable further back.
-
Dispose of Properly: Fiber optic shards are extremely sharp and can be dangerous. Dispose of cut pieces and debris properly. Use a designated container labeled for fiber optic waste.
Why a Clean Cut Matters:
A clean and precise cut is essential for several reasons:
- Optimal Signal Transmission: A clean break minimizes signal loss and reflections, ensuring the best possible performance.
- Proper Splicing: A straight and even cut is crucial for successful fusion splicing, allowing the fibers to align perfectly.
- Reliable Connections: Cleanly cut ends ensure reliable connections when using mechanical connectors.
Safety Precautions:
- Wear eye protection: Fiber optic shards can cause serious eye injury. Always wear safety glasses or goggles when working with fiber optic cable.
- Wear gloves: Wear gloves to protect your hands from glass shards and debris.
- Handle with care: Fiber optic cables are delicate and can be easily damaged. Handle them with care to avoid bending or kinking them excessively.
