Structured cabling and fiber optic ducts

Fiber optic cables — the backbone of modern telecommunications, broadband internet, enterprise networks, datacenter backbones, FTTH (Fiber-to-the-Home) projects — have an external jacket that protects the internal optical fibers from mechanical, chemical and environmental damage. Typical applications: aerial cables on distribution poles (severe UV exposure), underground cables in ducts, cables in indoor installations (with strict fire requirements), submarine cables (for intercontinental interconnections), cables for military and specialized industrial applications. TPU competes with polyethylene (PE), polypropylene (PP) and PVC in fiber optic jacketing, offering advantages in specific applications: extreme flexibility at low temperatures (−40°C), excellent abrasion resistance (important in aerial cables), durability in continuous flex, capability to integrate flame-retardant properties without compromising mechanical properties. Market in strong growth driven by massive expansion of 5G and FTTH infrastructure globally. Brazil with large fiber internet deficit to be supplied in the coming years.
