Heraeus Covantics | Telecom Fiber

Strong start at Laser Photonics China 🚀 Day 1 already highlights where the industry is heading: Higher precision, growing demands in semiconductor manufacturing, and a clear focus on advanced materials as the foundation for next-generation applications. At Heraeus Covantics, we are right at the center of these conversations – bringing expertise in high-purity quartz and advanced materials that enable tomorrow’s laser and photonics technologies. And most importantly: a team on site that turns this ambition into reality every day. 👉 Come visit us at our booth in the hall N3 / #3232 – we look forward to connecting and discussing what’s next for photonics.

The OFC Conference is approaching, a yearly milestone for our team to meet customers, align on market expectations, and learn about technology trends. Looking back, this "era" started with Hollow-Core Fiber around 2018. Ever since, every OFC surprised us with new applications, new technologies, and new markets opening up. And AI has certainly upped the pace. Heraeus Fiber will be represented by a strong suit of experts: Jan Vydra leading our Business Line, Dr. Ansgar Meissner for our Hollow-Core segment, Adriana Huerta Viga for our Multi-Mode Specialties addressing the ultra-short range, Martin Böttcher with Multicore Solutions for the backbone inside DC, for submarine and telecom spaces, Martin Schnell representing our Quartz Tube Solutions and our Product Application team, and Marc Schneider heading our US Sales. Let us know how we can support Your business!

🎉 Celebrating a milestone in Brøndby! On January 5, we welcomed two new colleagues to Heraeus Covantics – and with them, we’ve crossed an exciting threshold: more than 50 employees in Denmark! One of them is even number 50. Our Brøndby site plays a key role in the European optical fiber value chain. Here, we produce standard and bend-insensitive optical fibers for the EMEA market and drive innovation with advanced technologies like hollow-core and multi-core fibers. Supported by a strong R&D team, we’re shaping the future of telecommunications and photonics. We’re proud of the amazing team we’ve built and excited about what’s ahead. Thank you to everyone who made this possible – together, we’re on the right track for continued growth and innovation! #Heraeus #Covantics #Fiber #Hollowcore

🌐 Our team joined the APC Global Optical Fiber & Cable Conference 2025 in Nantong, where AI-driven data growth and next-gen fiber architectures shaped every conversation. In our presentation, we highlighted how our solutions — from F305 for MMF tubes and F520 for ULL designs to our multicore preform services and precision HCF tubes — support the industry’s shift toward higher performance and scalable optical infrastructure. Great discussions, strong momentum, and a clear sense that advanced fiber technologies will define the next stage of network evolution. #Heraeus #Covantics #HollowCore #OpticalFiber #Multicore #DataCenter

🎉 We’re pleased to announce that Heraeus Covantics will be participating in the IWCS 2025 Cable & Connectivity Industry Forum, taking place October 27–30 in Pittsburgh.   As one of the leading events for the global wire and cable industry, IWCS offers a platform for innovation, collaboration, and forward-thinking solutions.   One of the highlights: Our colleague Ruben Rivera, Specialty Fiber Sales Manager, will join an expert panel to present SOFIA – Sustainable Solutions for Power and Data Cables. This initiative brings together key industry players to explore how we can reduce environmental impact while advancing performance and reliability in cable systems.   🌍 At Heraeus Covantics, sustainability is at the core of our innovation strategy — and SOFIA reflects our commitment to shaping a more responsible future for the cable and connectivity industry.   We’re looking forward to thought-provoking discussions, new ideas, and meaningful connections in Pittsburgh.   #IWCS2025 #SOFIAInitiative #Sustainability #Heraeus #Covantics

☝ Update for LUMIRing_iscte Multicore Fiber testbed: In the meantime, a cable of 26 km with nearly 2,000 km of different types of multi-core fiber made by Heraeus Covantics is installed in the yellow subway line of Metropolitano de Lisboa. Iscte - Instituto Universitário de Lisboa is regularly publishing updates on the project website https://lnkd.in/dV5XMnKu and on their YouTube channel. In the middle of the night, when trains stop running, TELCABO S.A. installation team is at work: https://lnkd.in/euVutbMY

Thanks to Rebecca Schmieg & Tobias Tieß for visiting ECOC 2025 | 51st European Conference on Optical Communication for us. It took place in Copenhagen, where we also produce our optical fibers: #HCF #MCF While the discussion about the winning silicon technology is going into ever new rounds, one thing seems certain: Novel fiber types are needed to replace electric connections between GPU, and to increase reach and density of optical channels. #HCF: Hollow-core fibers carry light at higher speed, enabling the distribution of compute capacity across multiple data centers in a region which is key to training large AI models. We have recently announced our collaboration with Microsoft Azure to produce such fibers at large scale. At #ECOC2025, new designs with low attenuation and multiple testbeds were presented. #MCF: Multicore fibers are finally breaking through in market acceptance, as hyperscale data centers are burdened under loads of optical cables while compute and storage density keep soaring. Heraeus started to invest into both #HCF and #MCF development over six years ago, and we are glad to see these products entering the market now. At Heraeus, we keep enabling communication beyond todays imagination.

HCF – a breakthrough in fiber technology By guiding light through air rather than glass, Hollow Core Fiber (HCF) enables data to travel faster and with less attenuation – opening new possibilities for datacom networks. At Heraeus Covantics, we are leveraging decades of materials expertise and the dedication of our teams worldwide to make HCF ready for industrial-scale production for the Azure network. This innovation will help shape the data infrastructures of tomorrow, supporting everything from Cloud services to the growing demands of AI. We are proud to play a role in advancing this technology and thank our teams for their outstanding contribution.   👉 Learn more about HCF and our work on this innovation here: https://lnkd.in/eDqteyWH #Heraeus #Covantics #Hollowcore #Fiber #Innovation
