Pirelli's enhanced fibre specifications set new standards in the optical industry
June 5, 2002
MILAN -- 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 125±0.7µm with a coating diameter of 245 + 5µm. Furthermore, core/cladding concentricity error on Standard Single Mode fibre has been reduced by nearly 40% to a value of <0.5 µm, matching the tight tolerance already offered by FreeLightTM.Attenuation characteristics have been further improved. A reduction of 20% brings MagniLightTM 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.Pirelli Cables and Systems
