WIRE & CABLE | MATERIALS 5G ready
Another topical development impacting the wire and cable sector is the rollout of 5G networks, which requires significant upgrades to the existing telecommunications infrastructure, including the deployment of new types of cables capable of handling higher frequencies and data
rates.Dow said industry experts are predicting that 5G connections will more than double by 2025, and relaying such massive amounts of data to devices will require millions of miles of new fibre optic cables, putting the wire and cable industry under significant pressure. Luckily, advancements in mate- rials science have provided the means to design solutions that last longer, ease installation, improve performance, and provide greater reliability. Plus, with the introduction of small, mini, and micro fibre optic cables, systems can take up less space. “As cables are becoming smaller and denser, telecommunications technology must advance to eliminate any compromise on quality,” said Paul Brigandi, Senior Technical Services and Develop- ment Scientist, Wire and Cable, Dow Packaging and Specialty Plastics. “Dow’s Axeleron FO 6321 BK is [an] all-in-one solution for longer fibre optics
cable lifecycle protection. Designed for micro cables up to 60% smaller, 70% lighter, and packed more densely into conduits, it delivers up to 25% less shrinkage compared to traditional jackets which helps reduce the stress on cables that often leads to increased fibre attenuation.” Joanna Giovanoli, Market Manager, Infrastruc-
ture, Dow Packaging & Specialty Plastics, said: “Modernising our telecommunications infrastruc- ture to help address deficiencies and reliability in connectivity should begin with the right materials. Further, it’ll require collaboration across the value chain from compounders to material providers to manufacturers.” Fibre optic cable jacketing is often made from polybutylene terephthalate (PBT) to make use of its good mechanical properties and resistance to heat and chemicals. For ease of installation, optical fibre cable producers use a colour codification system. Among its ELTech portfolio, Ampacet has devel- oped a range of high performance colour master- batches based on PBT carrier resin specifically designed for optical fibre cable PBT Jacketing. The company’s standard ELTech portfolio for optical fibre cables includes 16 colours, complying with RAL
