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.) require infrastructures to be adaptable and robust enough to meet today’s
requirements and 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 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 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 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. The future. 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
