What is the difference between pulling and blowing/jetting a fiber optic cable?

2025-08-15

Pulling is the traditional method where a rope or tape is pulled through a conduit, which in turn pulls the attached cable. This is typically done with a winch or a manual puller. Pulling is effective for shorter runs or when the conduit has many bends.

Blowing (or Jetting) is a more modern method, particularly for long, straight runs. This technique uses a specialized machine that injects high-pressure compressed air into the conduit while simultaneously pushing the cable. The air creates a low-friction cushion around the cable, allowing it to "float" through the conduit over very long distances with minimal tension. Our expertise and equipment range cover both methods, from hydraulic winches for pulling to specialized cable blowers for jetting to meet all project needs.
