High Performing Fibre Optic Cables with Kevlar®
DuPont™ Kevlar® K29 AP and Kevlar® K49 AP fibre reinforcement help provide improved flexibility in the design and manufacturing of fibre optic cables.
Kevlar® K29 AP and Kevlar® K49 AP help provide the fibre optic cable industry with better-performing, more cost-effective products, and improved flexibility in cable design and manufacturing, mechanical properties, and coverage of the optic fibre.
For example, in premise cable tests, Kevlar® K29 AP light decitex yarn has 15% more tenacity and 28% more tensile modulus compared to Kevlar® K29 1000 decitex yarn, which can result in lower cable strain and higher cable load – with material savings that can exceed 10%.
Kevlar® K49 AP, which is suitable for outdoor/ADSS fibre optic cables, can help manufacturers either develop longer-span, more robust cables with the same number of para-aramid strength members or modify the design of existing cables to achieve material savings.
For single fibre optical cables, Kevlar® AP yarns also provide crush resistance, cushion protection and a more uniform coverage of the optic fibre, helping to make cable production more efficient.
