How to handle cut fiber optic patch cords

Fiber optic patch cords can be cut using manual tools like fiber cleavers and scissors or automated cable cutting machines, depending on precision and production scale.Manual Cutting MethodsFiber Optic Cleaver: A cleaver is the most precise tool for cutting optical fibers. It produces a clean, perpendicular end face, which is critical for minimizing insertion loss and ensuring proper connectorization or splicing .Kevlar or Fiber Scissors: Used to trim the outer jacket or Kevlar strands of the cable. These scissors are designed to cut tough materials without crushing the fiber inside .Measuring and Marking: Before cutting, measure the required length of the patch cord, including any reserved length for pigtails or connectors. Mark the cutting point carefully to maintain accuracy .Automated Cutting MethodsAutomatic Cable Cutting Machines: These machines are used in production environments to cut multiple patch cords quickly and accurately. They can handle various cable diameters and lengths, and often include functions for strapping, wrapping, and labeling .Transmission Shaft and Metal Wheel Setup: The cable is installed on the machine's transmission shaft, secured with a metal wheel, and the machine is powered on to perform precise cuts .Preparation and Post-Cutting StepsCoiling and Binding: After cutting, short cables (typically under 5 meters) are coiled and lightly bound to prevent damage .Stripping: Use a fiber jacket stripper to remove the outer jacket and tight-buffered coatings before connectorization .Cleaning: Clean the fiber to remove residues before inserting it into connectors or performing splicing .Polishing: After cutting and connector insertion, polishing ensures a smooth end face for optimal signal transmission .Key ConsiderationsAlways maintain a dust-free work area to prevent contamination.Avoid nicking or damaging the fiber during cutting or stripping.For high-volume production, automated machines improve efficiency and consistency, while manual methods are suitable for small-scale or field work . By following these methods, fiber optic patch cords can be cut accurately and safely, ensuring high-quality performance in optical networks.
