Air blowing cable installationIn 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 conditions1 1 2

Aerial optical cable installation
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

Solutions for special cable installationAd 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

Conclusions
Some of the Sirti’s latest years special solutions, studies and
projects for network construction have been illustrated
The avalability of a whole set of technical solutions and the
capability to properly customize them are two fundamental
requirements for a modern network and system integrator
