Pirelli expands mini-cable blown fibre family for metro and access networks
Milan, 20 January 2003 - Pirelli has made a significant addition to its blown fibre and cabling portfolio with the introduction of its mini-cable systems, delivering between 12 and 72 fibres per cable and providing telecommunications operators with unprecedented choice in their metropolitan and access network expansion strategies.
The option of installing further mini-ducts and, within them, appropriate mini-cables to reflect changing business conditions, offers significant cost-savings and gives operators tremendous flexibility in planning their networks.
Over the past two years in particular, mini duct systems have become increasingly popular. The most common applications involve small diameter ducts (typically 16mm, 12mm or 10mm) deployed within an existing mains duct.
Richard Thomas, Marketing Director, Pirelli Telecom Cables and Systems said: "As part of our continuing research programme over the past two years we developed and manufactured a range of small diameter cables that are optimised for installation within a wide range of mini-ducts. Our new mini-cable portfolio can also release hidden capacity in ducts that an operator previously considered fully occupied."
In a traditional 40 mm diameter duct, an operator can choose to deploy up to seven mini-ducts. 24 fibre cables for example could then be simply added over any period of time. "Our system offers the most flexible 'pay as you grow' architecture available. Operators have the distinct advantage of deferring all but essential capital investment in the network, building directly according to today's need. They can increase fibre count in line with demand, installing empty tubes initially and paying for fibre as and when they require," added Thomas.
Over 20,000 km of mini-cable fibre with up to 72 fibres per cable have already been installed in France. Pilot schemes of a variety of mini-cable sizes are underway with metropolitan operators in UK, Italy, Scandinavia and USA. And approval has been granted in Germany for the 60-fibre mini-cable, now available in a 6 mm construction, making it one of the smallest fibre cable packages commercially available.
Not only is Pirelli's bespoke range of cables designed to be blown into any part of the network, it is also supported by Pirelli's comprehensive range of passive optical accessories for a complete end-to-end system.
Pirelli works with experienced installation partners in each country, providing training and expertise in design, management and preparation of installation projects.
Notes for Editors
The use of "blown" fibre techniques to install optical fibre cable has been well established worldwide over the past decade. It can now be utilised in all parts of a telecommunications or large campus network, from trunk or backbone, through the metropolitan or access network to the "last mile" or customer premises itself. Mini-cables have to be considerably smaller than their conventional counterparts and have the properties enabling them to be blown up to two kilometres.
Pirelli Telecom Cables and Systems is one of the world's foremost suppliers of telecommunications cable systems and is part of the Pirelli SpA Group which employs more than 39,000 people in 84 plants across the globe. In 2001 it achieved a turnover of more than Euro 7,5 billion, continuing to maintain a strong emphasis on innovative research
