Tailored Insulations for High Transmission Rate Data Cable

摘要

Even with the spread of fibre optical cables into the communication access network, copper symmetrical twisted pah-data cables are still at the forefront of today's designs. As transmission rates increase, older "multi-purpose" insulations may not meet these new demands. Recent tailored solid polyethylene (PE) and polypropylene (PP) formulations for unscreened twisted pair (UTP) cables have provided some distinct advantages for the cable manufacturer. Foamed PE for screened data cables has seen recent advances in the quality of these insulations for Category 7 and Category 7A designs. Physical foaming insulations specifically designed for data cable can now allow manufacturers to optimise their line speeds and minimise scrap rates. This presentation will focus our experience with an optimised range of solid and foamed data cable insulation materials and a new enhanced PP solid insulation for Cat 6A designs.
