Blown Fibre achieves its cost-effectiveness and flexibility by separating links into a passive infrastructure and high performance optical cabling. The passive infrastructure is created with the specially developed miniature plastic ducting and a range of appropriate termination and routing accessories. The optical cabling is added with the minimum of disruption whenever required. Multimode or single mode optical fibres are blown into links, using sophisticated installation equipment but with distances up to 80M this can be installed with out air flow.
