Prysmian cites blown fiber milestone
September 9, 2008 -- Prysmian Telecom Cables & Systems announced that it recently installed its one-millionth fiber km via Sirocco, its blown fiber system.
The principle of blown fiber involves the pre-installation of an empty tube network into which optical fibers are subsequently blown-- using compressed air--as the network evolves under the demand for customer connections.
According to the company, the Sirocco system provides an ideal and cost-effective way to deliver fiber closer to the end user to support higher speed, higher bandwidth services. The system is particularly well suited to "Greenfield" residential sites, say Prysmian representatives, where an empty tube infrastructure can be included at the time of construction, thus deferring the fiber investment until actual consumer demand occurs.
Sirocco, produced at Prysmian's UK facility in Bishopstoke, has now been supplied globally to more than 20 countries in all five continents, claims the company. The landmark project took place last month in Denmark.
The system incorporates everything required to build a complete passive network, including tubing, fibers, joints, and connectors together with specialist installation equipment and engineering services. The optical fibers, also produced by Prysmian, are blown into the tubes in units of two, four, six, eight, or 12. The company's new CasaLight family of bend-insensitive fibers is also fully available and compatible with Sirocco technology.
