As fibre optic networks expand, the materials used to build them are evolving rapidly to keep pace with performance, safety, and environmental standards. Innovative materials are critical to meet demand for faster, more reliable connections, especially in high-density environments like data centres.
Today’s cable designs require a careful balance of flame retardance, flexibility, processability, and global compliance. From improving performance in challenging environments to meeting evolving regulatory and sustainability requirements, the right material choices can make a real difference.
Trends that drive the demand of fibre optic cable solutions
The uptake of fibre optics makes many of the tech trends powering our daily lives today possible. It’s all about high-speed internet, cloud computing and real-time communication. The 5G revolution demands dense, high-capacity connections. The explosion of AI requires high-speed connections to hyperscale data centres. Smart homes and buildings are adding billions of new devices to the Internet of Things. And remote working and education are boosting consumer demand, bringing broadband to the so-called last mile.
Innovative materials to meet the demands of an evolving industry
Several advanced materials are now available to help manufacturers innovate in the development of optical fibre cables. These solutions are designed to address key challenges, helping manufacturers stay agile and meet evolving market demands more effectively.
• Accelerating the shift towards halogen-free
Driven by increasing safety requirements and sustainability goals, halogen-free compounds resist flame and suppress smoke in the event of fire. They also help maintain low friction and structural integrity in complex fibre architectures. From standard indoor installations to jetted fibre systems and or compact subunit constructions, material performance supports efficient processing and long-term durability.
• Thin-wall jackets make space for more
Across various applications, manufacturers are looking to reduce the thickness of jacket materials, while retaining mechanical strength and flame retardance. This is key for high fibre-count configurations where space is limited and smoke suppression is critical. Similarly, the move toward plenum-grade materials delivers essential flame and smoke performance without the use of halogens. These offer a safer alternative to legacy compounds, like PVDF and FEP.
• Thermoplastics rising to the challenge
Fibre systems used for indoor/outdoor and riser-rated environments require compounds that combine low shrink, flexibility, and environmental resistance. Innovation is focused on materials that perform consistently across climate zones and regulatory jurisdictions. Beyond jackets, the industry is also investing in thermoplastic elastomers (TPEs) engineered for connectors, emphasizing precision, adaptability, and long-term mechanical stability.
What’s on the horizon?
Looking ahead, one of the most transformative shifts is the need for materials designed for immersion cooling. As fibre cables begin to operate in next-generation underwater data centres, the standard approach to materials is being redefined. Compounds must resist fluid absorption, prevent swelling or cracking, and maintain their structural and thermal properties while fully submerged.
Another exciting development is the near launch of a halogen-free flame-retardant materials, which will help round out the portfolio of flexible, non-halogenated solutions. This thermoplastic material is designed to meet high mechanical performance demands, while aligning with a growing preference for safer, low-toxicity compounds.
Sustainability is also driving innovation. Whether it’s low carbon, bio-based or recycled content, there’s strong momentum across all fronts. The industry is moving toward custom-tailored sustainable compounds that align with environmental goals without sacrificing performance. Promising new paths are emerging for fibre optics that reduce lifecycle emissions and minimise waste.
Compliance is key for peace of mind
Material innovation goes hand in hand with regulatory readiness. From North America to Europe and Asia, fibre optic cable compounds must meet an expanding set of chemical, environmental, and safety regulations. Global standards are evolving quickly, and staying compliant across regions is more critical than ever.

“While meeting regulatory requirements is essential, it's increasingly important to recognise the growing influence of leading tech companies like Google, Microsoft, Meta, and Amazon,” Guido Jodocy, Market Manager at IMCD Advanced Materials. “Because of their scale and sustainability commitments, their material expectations effectively shape industry standards. Aligning with these expectations is about staying competitive while delivering on relevant and responsible solutions.” |
