The blowing method appeared as a response to the need of efficiently installing optical cables in location with limited space. The basic principle is a simple one: compressed air blown from a special device pushes the cable into the microduct.
This technology is unique because it helps fill the microduct in a high percentage, between 50 and 80%. This results in forming an air layer which pushes the cable and dramatically reducing the friction with the inside walls of the microduct. Thus, there could be reached a speed of 60m/minute and distances of more than 2 km, if the pressure applied to the cable is minimized.
Benefits of this solution:
- Guaranteed solutions for the entire duration of network exploitation
- Long distances and short installation time
- High density of the number of cables installed
- Minimum number of necessary splicing
- Fast reconfiguration possibility
- Easy to extend and modernize the network
This solution is based on microducts, also known as microtubes. The microducts are small tubes specially built, which mechanically protect the micro fibre and have reduced friction during installation. To easily protect and install, these are grouped in bundles of up to 24 units. If ordered, we could deliver bundles with customized configurations.
In order to connect the microducts segments, we offer connectors, reductions, lids, splicing boxes, underground boxes and manholes optimized for such applications.
The cables themselves play an essential role in reaching good performance. There are two categories: the former is represented by miniature cables with up to 12 fibres wrapped in an aerodynamic cover. This is a very compact solution, between 1mm and 1.6mm diameters, being very useful for FTTH networks. The latter category has cables with up to 144 fibres. Their structure is similar to that of conventional cables, but smaller and lighter, to obtain longer blowing distances.
This solution also uses blowing devices produced by Fremco. These devices can blow cables with diameters between 0.8 and 25 mm in tubes up to 70 mm and are effective, reliable and easy to use. As compressed air source we recommend Kaeser mobile compressors.
Together with products and equipment we are also offering technical support, training courses and consultancy and design, installation and maintenance services for networks which use this technology.
We would like to contribute to a good understanding of optical cables blowing technique with a demonstration of the essential procedures which must be followed in order to obtain all the benefits of blowing techniques:
- reaching the maximum blowing distance
- reducing installation time and costs
- high density of the installed cables
In this test field we want to recreate faithfully a real route so that our clients could see with their own eyes the most important details they have to consider when implementing an underground network.
