Blowing

Blowing fibre optic cables ensure reliable underground communication networks. Building a cable duct system instead of aerial deployment allows to reduce plastics production due to a smaller diameter of blown cables and does its job in preventing visual pollution of urban landscapes caused by human-made structures.

The fibre optic cable blowing procedure generally includes 2 steps: – high density polyethylene (HDPE) duct pipe is buried in the ground; – the cable is jetted into the preinstalled duct with a pneumatic machine.

The pneumatic equipment provides a high speed of installation. A high-density polyethylene pipe protects the cable from ground movements, mechanical damage, rodent attacks and moisture. The tensile force during blowing is evenly distributed along the cable surface, that is why the designs don’t require high load resistance. Whatever your project needs are, Incab is sure to have a solution. We offer a wide range of optic fibre cables:
