What Is Cable Blowing?

Cable blowing (also known as jetting or floating) is a specialist method for installing fibre optic cable into pre-installed ducts using compressed air and precision machinery. This approach enables faster installation, longer continuous runs, and reduced stress on the fibre compared with traditional pulling methods.

Why Choose Cable Blowing for Fibre Installation?

  • Faster installation than traditional pulling

  • Reduced friction and fibre stress

  • Longer uninterrupted cable runs

  • Lower risk of damage during installation

  • Ideal for micro-duct and sub-duct networks

  • Cost-effective for large-scale deployments
