broadest possible spectrum of customer applications, such
as single-mode, multimode and specialty fibres.
Optical cables
Optical fibres are employed in the production of standard
optical cables or those specially designed for challenging or
inaccessible environments. The optical cables, constructed
using just a single fibre or up to as many as 1,728 fibres, can
be pulled (or blown) into ducts, buried directly underground
or suspended on overhead devices such as telegraph poles
or electricity pylons. Cables are also installed in road and
rail tunnels, gas and sewerage networks and inside various
buildings where they must satisfy specific fire-resistant
requirements. Prysmian Group operates in the telecommu-
nications market with a wide range of cable solutions and
systems that respond to the demand for wider bandwidth
by major network operators and service providers. The
product portfolio covers every area of the industry, including
long-distance and urban systems, and solutions such
as optical ground wire (OPGW), Rapier (easy break-out),
Siroccoxs (fibres and cables for blown installation), Flextube®
(extremely flexible easy-to-handle cables for indoor or
outdoor installations), Airbag (dielectric direct buried cable)
and many more.
Connectivity
Whether deployed in outdoor or indoor applications,
Prysmian Group's OAsys connectivity solutions are designed
for versatility, covering all cable management needs
whatever the network type.
These include aerial and underground installations, as well
as cabling in central offices (or exchanges) or customer
premises. Prysmian Group has been designing, developing
and making cable and fibre management products for
more than two decades and is at the forefront of designing
next-generation products specifically for Fibre-To-The-Home
(FTTH) networks.
FTTx
Increasing bandwidth requirements, by both business and
residential customers, are having a profound effect upon the
optical network performance level required, which in turn
demands high standards of fibre management. Optimal fibre
management in every section of the network is increasingly
a matter of priority in order to minimise power loss and
overcome the problems caused by ever greater space limita-
tions. The Group has developed the suite of xsNet products
for "last mile" access networks, which is also very suited to
optical fibre deployment in sparsely populated rural areas.
Most of the cables used in FTTx/FTTH systems feature
Prysmian's bend-insensitive BendBrightxs optical fibre,
which has been specially developed for this application.
FTTA (Fibre-To-The-Antenna)
xsMobile, which offers Fibre-To-The-Antenna (FTTA)
solutions, is an extensive passive portfolio which enables
mobile operators to upgrade their networks easily and
quickly. Incorporating Prysmian's experience in Fibre-to-
the-Home (FTTH) and its unique fibre innovations, xsMobile
consists of different product solutions for three applications:
antenna towers, roof-top antennas and Distributed Antenna
Systems (DAS) for small cell deployment. The technology
offers three access types for outdoor and indoor FTTA de-
ployment, as well as backhaul solutions – incorporating the
latest fibre technologies.
Copper cables
Prysmian Group also produces a wide range of copper cables
for underground and overhead cabling solutions and for both
residential and commercial buildings. The product portfolio
comprises cables of different capacity, including broadband
xDSL cables and those designed for high transmission, low
interference and electromagnetic compatibility.
Multimedia Solutions
The Group produces cable solutions for a variety of appli-
cations serving communication needs in infrastructure,
industry and transport: cables for television and film studios,
cables for rail networks such as underground cables for
long-distance telecommunications, light-signalling cables
and cables for track switching devices, as well as cables for
mobile telecommunications antennae and for data centres.
