Optical Fibre
Prysmian is one of the world's largest producers of high quality, high
performance optical fibre. These products range from long distance submarine grade fibres
(DeepLight) and terrestrial fibres (FreeLight and WideLight) meeting ITU-T G.655 requirements, to
short haul fibres for access and premise networks. It is these latter fibres that are used in
Sirocco.
The datasheets accessible below identify the optical and geometric properties of the various
fibre types used in the manufacture of the Prysmian range of Sirocco fibre bundles. If you require

• Singlemode Fibre
The Optical Fibre that sets Standards
Standard singlemode optical fibres are most suitable for the 1310nm wavelength range, but
can also be used at 1550nm. This allows singlemode fibre to be used with a variety of sources, from
LED's to lasers, offering a highly versatile fibre carrying high bit rates on multiple channels.
Prysmian singlemode fibre is compatible with other fibres and employed across the world in optical
systems.
• MagniLight Fibre
Low water peak singlemode fibre offers the possibility of extra bandwidth (65% more usable
wavelengths) by reducing the water peak around 1383 nm enabling it to be used with current and
emerging technologies that can reduce network costs by increasing transmission capacity.
• Multimode Fibre
The best solution for local applications.
Multimode fibres are intended for all applications where the distances covered are short,
such as Local Area Networks (LAN) or all networks with a small reach like campus, buildings or
offices. A multimode fibre also enables connections for backbone, riser and horizontal links. All
these networks are characterised as having many points of access to the fibre and the short
distances covered. The index profile of multimode fibres is specifically tuned to provide the
optimum solution for these local applications.
The range of multimode fibres has been extended over the last few years in order to offer
solutions for 10 Gbit operation. Prysmian now manufactures Sirocco fibre bundles with four options
of multimode fibre.
Prysmian fibres are manufactured using Neon technology, where a coloured
layer of acrylate is applied to the fibre during drawing instead of adding an inked layer
afterwards. The advantages offered by this technology include:
• Improved watersoak performance, fibres have been immersed in water for
almost 10-years with no sign of degradation
• Better control of finished fibre dimensions, particularly valuable in
ribbon fibres
• More lucid, vibrant colours for easy differentiation when
splicing
