Rosendahl Nextrom brings cutting-edge cable and fiber manufacturing to Interwire

At Interwire 2025, Rosendahl Nextrom will present its latest innovations in cable and fiber production, built to power the global digital infrastructure in the era of AI.

Comprehensive solutions for datacom and telecom

Rosendahl Nextrom offers a full suite of manufacturing technologies spanning the entire fiber journey—from preform to finished cable. Their portfolio covers all phases of fiber optic cable production and provides insulation and sheathing solutions for a wide range of metal communication cables. 

Key highlights at this year's event include:

High-temp foam extrusion for AI-ready cables

Rosendahl’s high-temperature foam extrusion technology for Twinax cables is setting new industry benchmarks. This advanced insulation process supports ultrafast data rates and minimal latency, vital for the next generation of AI-driven data centers.

Fiber optics: responding to new demands

The expansion of AI data centers in the US is driving strong growth in fiber optics, while FTTx continues to be a stable market force. Rosendahl Nextrom addresses these needs with cutting-edge technologies, including:

↣ Specialty fiber production: As demand for hollow-core and bend-sensitive fibers rises, advanced solutions for preform manufacturing, fiber drawing, coating, and proof-testing become essential.

↣ Premise cable manufacturing: The rise of AI infrastructure calls for robust, low-loss fiber optic cables for indoor and interconnect uses.

↣ Drop cable production: Expanding FTTx networks need efficient, scalable drop cable solutions for reliable last-mile connectivity.

↣ Ribbon cable processing: With the trend toward high-density networks, Rosendahl’s ribbon production lines enable high fiber counts with optimized installation and splicing.

Enabling autonomous driving and next-gen mobility

In automotive technology, Rosendahl introduces the first industry-ready PEEK extrusion line for hairpin wire, along with solutions for busbar insulation and automotive cable production. These developments support the transition toward autonomous vehicles and 800V+ power systems.

Advancing energy cable production

As demand surges across mobility and telecom sectors, the power grid must evolve. Rosendahl’s innovations in the energy field focus on efficiency and material conservation, featuring high-speed low-voltage insulation, cost-effective alternatives to XLPE for medium-voltage applications, and flexible metal shielding for high-voltage cables suited to subsea and land installations.

Local support with a global reach

With a dedicated sales and service team based in the US, Rosendahl Nextrom ensures prompt on-site support and fast delivery of original spare parts, maintaining long-term performance for its customers' production lines.
