In 1996 Sirti Polska carried out the crossing of Vistula river near the centre of Warsaw by means of a 770 m directional drilling
In 1996 Sirti Portugal carried out the installation of an 840 km optical cable link along a TRANSGAS gas-pipeline by means of air blowing • 6 km optical cable drums were used • 4 intermediate blowing points for each cable drum were located by means of calculations in order to consider installation conditions
Air blowing installation main features: • Cable diameter: 13 mm • Cable weight: 150 g/m • Duct inner diameter: 41 mm • Air speed: 3000 m/min. • Cable speed: 50 m/min. • 1-2 cable drums (6-12 km) a day on average Sirti Portugal’s TRANSGAS Project
Since 1983 (Suvereto, Italy, 1000 kV power line for ENEL) Sirti has been installing aerial optical cable of different types. Present activities are: • ADSS cable: 100 km link for Telecom Colombia (350 m of cable for each span) • OPGW cable: 300 km link for ENEL • Wrapped cable: 1300 km link for ENEL
Ad hoc, low cost and easy istallation solutions for special situations are often directly designed by Sirti The installation of a leaky cable for mobile services into a railway tunnel is carried out by means of properly designed accessories
All dielectric broad band link • 2 GHz downstream bandwidth • Low environmental impact • Easy installation • Full compliance with future network and service evolution • Up to 4 user terminal equipment • Low cost
