What is YellowDuct?

🔹 YellowDuct® is the flexible, modular cable tray system for fiber optic cables, designed to route cables neatly and safely between terminal equipment, patch panels, and fiber optic splice closures or frames.

🔹 The system was developed by Warren & Brown, a manufacturer with decades of experience in cable management and telecom solutions.

 

Safety and sustainability are central
Mulder-Hardenberg emphasizes that YellowDuct®:

🔹 is halogen-free and complies with Low Smoke – Zero Halogen (LSZH/LS0H), so that in the event of fire, hardly any smoke or harmful gases are released.
🔹 is made of Noryl and is fully recyclable — according to the “cradle-to-cradle” principle — and contains no cadmium or halogens.

 

Flexible, modular and easy to maintain

The system is modular and includes a wide range of components: straight lengths, bends, T-pieces, storage loops, adapters, and much more. This makes expanding or adapting infrastructures easy.

Thanks to smart mounting options, installation is quick and efficient — reducing costs and downtime.

 

Who is it relevant for?

YellowDuct® is ideal for environments with large or complex fiber optic installations—think data centers, server rooms, telecom exchanges, universities, and hospitals.
Existing infrastructures can also be expanded or modified relatively easily, thanks to its compatibility with adapters and modular design.

 

Conclusion
With YellowDuct®, Mulder-Hardenberg and Warren & Brown/Prysmian offer a future-proof cable duct that combines safety, sustainability, and flexibility. This system is a solid choice, especially for organizations with critical fiber optic infrastructure, and significantly simplifies network management, maintenance, and expansion.
