OPTICAL FIBRE SUBMARINE REPEATER CABLE WITH COMBINED INSULATION/JACKET AND COMPOSITION THEREFOR

摘要

An optical fibre submarine repeater cable with combined insulation/jacket is disclosed as well as a composition therefore. The optical fibre submarine repeater cable with combined insulation/jacket is characterised in that the combined insulation/jacket comprises a multimodal polyolefin with a density of 0.910-0.960 g/cm<3> and an MFR2 of 0.2-6.0 g/10 min, and that the combined insulation/jacket is free from particles with a dimension larger than 0.5 mm in a 1 kg sample of material. Preferably the multimodal polyolefin is selected from ethylene and propylene (co) polymers and is bimodal.
