Blown fibre systems reduce material and installation costs, need fewer fibre connection points, greatly simplify the repair and maintenance requirements and create a migration path for future applications.

In short, blown fibre is glass fibre optic cabling that is blown through a duct using compressed air instead of being hauled or pulled through.

The air blown system mitigates drag as the airstream created from the compressed air lifts the fibre away from the surrounding wall of the ducting, reducing the friction applied to cable and lowering the force required to push the cable through the duct. The benefits of blown fibre include: a much-simplified planning requirement, due to its versatile installation process; the speed of installation is greatly increased; it is a greener option compared to traditional cabling methods; and it is a more cost-effective solution.

Blown fibre is a highly flexible solution for the Australian landscape

The microducts through which these fibre units are blown are manufactured of tough, flexible materials and bundled in groupings of up to 26 colour-coded micro ducts, forming a multi-duct assembly. These multi ducts can be installed above ground, aerially, underground or within buildings. Installation is simplified versus traditional methods as by using couplers, installers can easily connect individual microducts within assemblies to create pathways through which micro cables or fibre units can be blown to achieve splice-free, point to point, high-speed connection. As the pathways are laid during the initial civil phase of construction, specialist cablers or splicers are not required on site until the fibre is required to be connected. In addition, any damage to the microducts during the initial or any subsequent phases prior to connection can be repaired easily, without needing to splice or replace any fibre cable.

Fibre to the home is the preferred architecture for access networks worldwide. The versatility of air blown fibre systems provide a reduced total cost of ownership, improved network performance and offers advantages to both the network operator and the end-user.
