Composite Optical Cable Opening Techniques

Opening a composite optical cable involves carefully removing the protective sheath, separating the fiber and copper components, and preparing them for connection or splicing.

Step-by-

Step Process1. Safety and Preparation Before starting, wear safety glasses and gloves to protect against fiber shards and sharp copper edges. Ensure the work area is clean and well-lit, and avoid looking directly into fiber ends that may carry laser light, as this can cause serious eye damage.

2. Removing the Outer Sheath Use a cable stripper or utility knife to carefully remove the protective outer tube of the composite cable without damaging the internal fibers or copper wires. Expose enough length to work comfortably, typically a few inches beyond the intended connection point.

3. Separating Fiber and Copper Components Once the sheath is removed, separate the optical fibers from the copper conductors. For copper wires, strip 5–8 mm of insulation to prepare for connection.

For fibers, handle them gently to avoid bending beyond the minimum bend radius, which can cause signal loss. 4. Connecting Copper Wires Attach the copper wires to the appropriate terminals or connectors.

This may involve using a crimp tube or terminal block, ensuring correct polarity (e.g., red wire to red-marked conductor) and securing the connection with heat shrink tubing or adhesive as needed. 5. Splicing or Connecting Optical Fibers Splice the optical fibers using a fusion splicer or mechanical splice, then store the spliced fibers in a secure enclosure such as an 86 box.

Test the optical power or loss with an optical power meter or OTDR to ensure proper transmission. 6. Securing the Cable Run the composite cable along its route, securing it with clamps or hangers.

Avoid sharp bends, excessive tension, or crushing forces, as these can degrade both fiber and copper performance. 7. Final Checks Verify that all connections are correct, fibers are properly spliced, and copper wires are securely terminated.

Ensure the installation meets environmental and safety standards, including waterproofing if required. By following these steps, a composite optical cable can be safely opened, separated, and prepared for reliable data and power transmission in applications such as surveillance systems, industrial automation, or data centers.
