Enhanced Fibre Specifications set new standards

Pirelli, The Architects of Light, have set another milestone in their history of optical technology.

Pirelli's enhanced fibre specifications set new standards in the optical industry.


Milan, 3rd June 2002 - Pirelli Telecom Cables and Systems announces a new set of improved specifications for three key products in its optical fibre range; Standard Single Mode, MagniLight and FreeLight fibres.

Providing tighter specifications permits cable manufacturers and network operators to build their products and services on a high quality foundation. Several important parameters have been modified providing enhanced optical performance together with improvements in geometrical characteristics, which impact on critical operations such as splicing.

All three fibre types, Standard Single Mode, MagniLight (G.652 fibre with the 1385nm water peak removed) and FreeLight (G.655 fibre for long distance, high bit rate applications) have benefited from Pirelli's process improvements. Both the fibre cladding diameter and external coating diameter now feature tolerances tightened by 30%; the cladding diameter is now 1250.7m with a coating diameter of 245 5m. Furthermore, core/cladding concentricity error on Standard Single Mode fibre has been reduced by nearly 40% to a value of ≤ 0.5 m, matching the tight tolerance already offered by FreeLight.

Attenuation characteristics have been further improved. A reduction of 20% brings MagniLight down to 0.20dB/km at 1550nm and the fibre now also exhibits a best in class measurement at 1625nm of ≤ 0.24dB/km. Standard Single Mode fibre instead features an improved attenuation at 1385nm of ≤ 1.0dB/km. Whatever the band the operator wishes to use, be it the existing C-band or the emerging L-band or the futuristic E-band, Pirelli fibre offers the best solution.

" How can you tell a world class fibre? I think from the confidence a manufacturer has in the repeatability and integrity of the production process. And Pirelli has transformed this confidence into a reality for our customers" said Sergio Antoci, Senior Product Manager, Fibre and Preforms.

In addressing the area of Polarisation Mode Dispersion (PMD) Pirelli can now offer a world best for Standard Single Mode fibre, halving the fibre PMD coefficient to ≤ 0.1ps km. These results have been obtained by significant and continuing investments in research and development, confirming Pirelli's intention to continue taking the lead in the future of optical technologies.

" With this new record of fibre PMD coefficient, Pirelli maintains its single mode fibres as the best foundation to support future transmission at 40Gbit/s and above" added Antoci.

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 7,500 billion, continuing to maintain a strong emphasis on innovative research.
