For almost all applications in the access network and premise distribution, Sirocco® offers a cost effective alternative to traditional cabling. Pre-install a multi-tube link, then blow a package of 2 to 12 fibres into a tube, for Day 1 operations. Subsequently, when and if additional capacity is required, more bundles of fibre can be blown into adjacent tubes. This increases network design flexibility, reduces initial expenditure and increases the speed of subsequent service provision. Sirocco® blown fibre offers solutions for:

Private Networks (LAN/WAN/Campus) 
The arrival of the digital age has meant an ever increasing demand for bandwidth within all types of private networks, whether they be small office/industrial premises or the largest campus-type environments. Demand changes not only in bandwidth but also delivery locations (desks, buildings etc.) requiring infrastructures to be adaptable and robust enough to meet today’s needs and to be future-proofed for many years to come. Sirocco® provides a simple solution to add more fibre, extend the reach of the fibre network, or introduce the next generation of fibres as demand changes, with minimal disruption and cost. Some typical applications for private networks are listed below: 

 •  University Campus
 •  High-rise Office Blocks
 •  Industrial Sites
 •  Hotels/Entertainment Complexes
 •  Airports
 •  Military Sites
 •  Government Buildings
 •  Corporate Offices
 •  Hospitals
 •  Railways/Metros

Access Networks
The provision of an optical fibre connection would be justified for almost all business customers. The issue for any telecom operator supplying a service to a new customer in a multi-tenanted office block particularly, but even with its own building, is how much capacity to provide. The solution, to avoid later civils cost of a re-dig or installation of a further cable, has traditionally been to put in more capacity than is likely to be needed. It has been quite common throughout Europe, for example, when a new customer was recruited, to install a 12 fibre or 24 fibre cable, sometimes even a 48 fibre cable, even though today’s capacity requirements were only about 4 fibres.

Using Sirocco® blown fibre for business connections in an access network means:

  •  Install the fibre required for today’s operation
  •  Leave spare tubes for future upgrade
  •  Add fibre when and if more capacity is needed
  •  Minimise up-front investment
  •  Tie further investment to revenue growth

Fibre To The Home (FTTh)
The arrival of fibre is seen by many as the ultimate objective in bringing advanced facilities to people at home. For some, the future is here, with FTTh applications springing up around the globe. For most, the arrival of FTTh is ‘sometime in the future’. With Sirocco®, the potential exists, particularly for new build projects, to install the tubes ‘fibre-ready’. On ‘ green field sites’, telecommunications becomes the fourth utility, alongside electricity, gas and water, laid ready for use. Adding a network of tubes, at the same time as providing the other services, reduces build costs while avoiding the higher, perhaps unnecessary cost of dark fibre provision. Then, as the falling price of service attracts different groups of customers (innovators, early adopters, followers etc) a fibre bundle can be blown in to supply the service required, where it is required.

Sirocco® is most commonly used for the distribution or drop elements of the following passive network topologies:

  •   Point to Point, Point to Multipoint
  •   Converged Passive Optical Network (PON)
  •   Cascaded Passive Optical Network (PON)
  •   Distributed Passive Optical Network (PON)
