With the Draka LongLine™ optical fiber, Draka is offering the benefit of its trench assisted design for ultra-long-haul applications, allowing increased distance without regeneration and easy cabling ability. The LongLine™ fiber exhibits an extremely high effective area of 120 μm², 50 % higher than standard single-mode optical fiber. It dramatically reduces the non-linear effects offering the possibility of higher power and consequently higher distance. The very low attenuation in the C- and L- bands further enhances the distance capacity while preserving system margins. The trench assisted design keeps macro-bending and micro-bending to a very low level making it suitable for any cable design.
In addition the LongLine™ optical fiber has chromatic properties compatible with commercially available chromatic dispersion modules or reverse dispersion fibers, like used in repeatered submarine applications. The Draka LongLine™ optical fiber is available at different screen test tensile strengths, according to application and customer request, 2 % strain equivalent notably available for submarine applications.
