Stripping of Six-Core Optical Cable

Proper stripping and fixing of a 6-core optical cable requires careful layer-by-layer preparation, precise cleaving, and secure splicing to ensure optimal signal transmission.

Tools and Preparation

Before starting, ensure you have a clean, well-lit workspace and the following tools: fiber optic stripper, fiber optic cutter, cleaver, crimper, alcohol wipes, inspection microscope or visual fault locator (VFL), and connectors or splice protection tubes . For multi-core cables, also have nylon cable ties and a storage tray for organizing fibers .

Stripping the Cable

1. Outer Jacket Removal: Strip the outer jacket carefully using a wire stripper of the correct gauge. Avoid cutting the underlying aramid yarn, which provides tensile strength .
2. Aramid Yarn and Buffer Stripping: Remove the aramid yarn and then the individual fiber buffers progressively. Each layer should be stripped to the manufacturer's recommended length, ensuring no damage to the fibers .
3. Cleaning: Use alcohol wipes to remove debris and dust from the stripped fiber ends .

Cleaving and Inspection

• Use a fiber optic cleaver to create a clean, perpendicular end face on each fiber. Adjust the cleaver according to the fiber diameter and desired cleave length .
• Inspect each cleaved fiber with a microscope or VFL to ensure there are no cracks, nicks, or irregularities .

Fixing or Splicing the Cable

1. Trim Damaged Ends: If the cable is cut or frayed, trim the ends with a fiber optic cutter to remove damaged sections .
2. Insert into Connectors: Place the stripped fiber ends into metal terminals or inline connectors and crimp securely using a fiber optic crimper .
3. Splicing: For permanent repairs, use fusion splicing or mechanical splicing. Align fibers carefully, splice one by one, and place them in protective tubes. Heat or secure the tube as required .
4. Organize and Secure: Pre-reel the fibers into a storage tray, fix both ends with nylon ties (not too tight), and cut off any excess fiber .

Final Steps

• Test the connection using an optical power meter or VFL to ensure proper signal transmission .
• Seal the splice box evenly with sealing tape and close the cover to protect the fibers from dust, moisture, and mechanical stress . By following these steps, you can safely strip, prepare, and fix a 6-core optical cable, maintaining signal integrity and minimizing the risk of fiber damage.
