Challenge: Uninterrupted, lightning-fast connectivity

Information needs to flow seamlessly, connecting you to what matters most – anytime and anywhere. From across the globe, lightning-fast connectivity isn’t just a luxury, it is a necessity. Say goodbye to the frustration of dropped connections and welcome to the era of uninterrupted high-speed communication. In today’s fast-paced world, every second counts and every connection matters.

At the core of tomorrow’s connectivity lies advanced optical fiber technology. Covestro leads the way with our Desolite® portfolio of primary and secondary coatings for optical fibers in the telecom industry. Our innovative solutions ensure that next-generation fiber optic networks can perform at their full potential, enabling faster and more reliable connections worldwide.

Key Drivers

  • Avoid Signal Loss

    Avoid Signal Loss

    Tiny bends in optical fibers, called microbending, can cause signal loss. Our Desolite® portfolio of primary and secondary coatings for optical fibers is engineered to protect against microbending, optimizing your telecom infrastructure to perform at its peak.

  • Durability of 35+ years

    Durability of 35+ years

    Advanced materials, technologies, and manufacturing processes are driving modern, high-quality optical fiber and cables beyond their expected 35-year lifespan. Leading manufacturers now claim their products may have lifespans exceeding 50 years.

  • Fit for Future Coatings

    Fit for Future Coatings

    We actively pursue alternative solutions that meet evolving regulations while advancing communication standards. We do this by combining sustainability with high performance, high-speed capabilities, and robustness—key for optical fiber production.

Status: Advanced Optical Fiber Coatings for Extraordinary Performance

We stand on the brink of a new era—a world where people and devices are seamlessly interconnected. This connectivity isn't just about technology; it's about unleashing human potential. As we connect, creativity flourishes, societies prosper, and people grow closer. At the heart of this transformative connectivity lies a powerful technology: optical fiber.

Built on decades of expertise
Our journey is built on four decades of expertise. For 40 years we have collaborated with industry leaders including fiber makers, cable producers, and telecom partners, to continuously push the boundaries of optical communication technology. This rich history fuels today’s innovations.

Leading the way in optical fiber coatings
As pioneers in the industry, we are also leading the charge in sustainability. We have developed groundbreaking LED-curable coatings, aligning with the industry's shift from Microwave to UV LED curing. This isn't just a technical advancement; it's an environmental win, with UV LEDs using 30-70% less energy than traditional methods.

Comprehensive solutions for optical cable and fiber
Our commitment to progress doesn't stop there. We offer a comprehensive suite of materials for optical cable and fiber applications:

  • Inks for clear identification
  • Matrix materials for structural integrity
  • Tight buffer materials for protection
  • Splicing compounds for seamless connections
  • Specialty fiber coatings for enhanced performance

The result? High-quality, reliable optical fiber solutions that meet the ever-evolving needs of our digital world. But we're not stopping there. Our dedication to sustainability and cutting-edge research ensures that we will continue to lead the way in optical fiber materials for years to come.

At Covestro, we do more than supply materials for the telecommunications industry. Our coatings help optical fiber connect to data centers, networks, homes, and businesses worldwide, bridging the digital divide and fostering connections between people, ideas, and possibilities.

Join us in illuminating the path to a brighter, more connected future.

Facts & figures

  • Increasing Data Consumption

    Increasing Data Consumption

    One hundred and eighty-one zettabytes* - that’s the amount of data expected to be created, captured, copied and consumed globally in 2025 – nearly three times as much as in 2020. ¹

    * 1 zettabyte (ZB) =1012 Gigabytes(GB)

  • AI Demands More Data

    AI Demands More Data

    AI demands five times more fiber in data centers compared to traditional computing systems. This astonishing statistic underscores the critical need for reliable and high-performance optical fiber solutions. This is where we step in and shine at light speed. ²
