What to do about the hollow part in the middle of the optical cable splice

A hollow or empty space in a fiber optic splice should be filled and protected using splice protection sleeves and proper sealing to maintain signal integrity and prevent environmental damage.Understanding the Issue

A hollow part in the middle of a splice typically indicates that the fiber ends are not fully supported or that the protective sleeve is missing or improperly installed. This can lead to signal loss, fiber movement, or environmental exposure such as moisture or dust, which can degrade performance over time .

Steps to Fix the Hollow
  1. Inspect the Splice Carefully examine the splice to ensure the fiber ends are properly aligned and fused (fusion splice) or mechanically joined. Any misalignment should be corrected before addressing the hollow .
  2. Use a Splice Protection Sleeve
    • For fusion splices, slide a heat-shrink sleeve over the splice. These sleeves often contain a reinforcing metal rod or gel to fill gaps and provide mechanical support .
    • For mechanical splices, use the manufacturer-recommended protective cover or gel-filled sleeve to occupy the hollow space and stabilize the fibers .
  3. Apply Heat or Sealant
    • Heat the sleeve with a heat gun to shrink it tightly around the splice, ensuring the hollow is completely filled and the fibers are immobilized .
    • For outdoor or exposed installations, consider additional sealing with waterproof gel or closure systems to prevent moisture ingress .
  4. Secure in a Splice Tray or Closure Place the protected splice in a splice tray or closure to prevent bending, pulling, or accidental damage. This also ensures the hollow area remains supported and the splice stays stable .
  5. Test the Splice After protection, verify signal integrity using an OTDR or visual fault locator to ensure minimal loss and confirm the splice is secure .
Key Considerations
  • Never leave a splice exposed; even a small hollow can compromise the fiber over time.
  • Ensure the sleeve or filler material matches the fiber type and splice method.
  • Properly supported splices extend the lifespan of the cable and reduce the risk of repeated repairs . By following these steps, the hollow in the splice can be effectively filled, protecting the fiber and maintaining optimal network performance.
