How to strip OPGW optical cable

Stripping an OPGW cable requires careful preparation, removal of metal layers, and precise exposure of the fiber cores using specialized tools to avoid damage.Preparation

Before stripping, ensure the cable is straightened over at least 2 to 2.5 meters to prevent twists or kinks, which can cause microbending and signal loss . Mark the length to be stripped with a marker and secure it with tape to maintain accuracy during cutting. Always wear safety gloves and a face shield to protect against sharp metal strands .

Removing Outer Layers

1. Secure the cable in a clamp or suitable holding device to prevent movement .
2. Cut the aluminum or steel strands carefully using a metal saw or mini grinder, taking care not to damage the inner fiber tubes .
3. Remove the outer metallic layers and smooth any sharp edges with a file to prevent fiber damage .
4. Separate the metal loose tubes gently to expose the fiber-containing tubes without crushing them .

Exposing the Fiber Cores

1. Use specialized fiber strippers to remove the protective jackets from the fiber tubes .
2. Clean the fibers thoroughly with appropriate fiber cleaning tools to remove dust or contaminants, which can cause signal loss .
3. If fusion splicing is intended, place a heat-shrink tube over the cable before stripping to facilitate later sealing .

Tools and Safety

• Metal saw or mini grinder
• File for smoothing edges
• Fiber strippers and cleavers
• Clamps for securing the cable
• Gloves and face shield for personal protection

Key Tips

• Handle the cable gently to avoid microbends or kinks.
• Always measure and mark accurately to prevent unnecessary waste.
• Clean fibers meticulously before splicing or termination to ensure optimal signal transmission. Following these steps ensures that the OPGW cable is stripped safely and correctly, maintaining both the mechanical integrity and optical performance of the fibers .
