Fibre module bundles 12 in one
Pirelli Telecom Cables and Systems has added a 12-fibre single-mode module to its Sirocco range of blown fibre products.
Pirelli Telecom Cables and Systems has added a 12-fibre single-mode module to its Sirocco range of blown fibre products used to achieve low cost network start-up, flexibility for network growth and rerouting The Sirocco 12-fibre module provides an important addition to the range of options for network operators and IT managers assessing the most practical and cost effective solution to their network build strategy

Fibre fits round tighter bends
Bend-intensive fibre exceeds the recommendations of ITU G657.B.
Fibre is fit for last mile infrastructure
Novel "bend-insensitive" optical fibre meets ITU-T recommendations for fibre to the home applications.
Blown fibre units of two or four fibres have been available since the early 1990s, and the range was extended to eight fibres in the late 1990s.
For network operators looking to connect from a metro ring to a new customer, standard practice has been to install a traditional 12, 24 or a 48-fibre cable.
The Sirocco system now allows a 12-fibre module to address this need with a cost effective initial connection and scope to grow.
Direct connection from the access networks to internal communications rooms or even direct to the desk is made achievable with this technology.
A new design was necessary to accommodate 12 fibres.
The standard design is a three-layer UV-cured acrylate matrix, with the inner a low modulus layer to prevent microbending, a high modulus layer for protection and finally a low friction coating containing microspheres to optimise blowing performance.
These designs are being manufactured exclusively by Pirelli under licence from BT Group and used extensively by them in the UK, overseas and by others (such as in the gambling centre of Sun City, South Africa).
The higher fibre count module uses a Pirelli patented process to bundle the fibres together in a small, light, easy-to-remove coating with a surface modified layer to produce good blowing performance.
Typical breakout times for the 12-fibre module are 1min and it can be blown a distance of 600m in about 20min.
These features, and similar performances for the lower fibre count modules, make the installation of blown fibre (or air blown fibre systems as they are known in North America) a rapid means of providing customer connections (residential or business) or within internal networks (building or campus).
Following a revision to its BT licensing agreement Pirelli can now supply Sirocco products in the UK as well as throughout the rest of the world, and is actively working with partners to develop new applications.
