DSM Functional Materials, a business unit of Royal DSM N.V., and Prysmian Group say they have inked a multi-year agreement for the use of DSM's latest-generation optical fiber coating technology, DeSolite Supercoatings, in Prysmian’s bend-insensitive fiber products. The agreement extends cooperation between the two companies and pairs DeSolite Supercoatings with the BendBright-XS fiber Prysmian acquired through its acquisition of Draka (see “First phase of Prysmian/Draka integration completed”).

The coatings are designed to improve signal attenuation performance by reducing the fiber’s sensitivity to microbends. The coatings therefore increase stress tolerance and improve processing and field robustness, says DSM.

"The advanced DeSolite Supercoatings that DSM supplies for the production of BendBright-XS bend-insensitive fibers are important components for the performance of these products," said Alain Bertaina, optical fiber product line manager, Prysmian Group. "When combined with Prysmian Group's advanced PCVD process technology, DeSolite Supercoating formulations help secure the enhanced bending attributes of BendBright-XS. We are pleased to extend our strategic supplier relationship with DSM on this key matter."

"We have a close, collaborative relationship that centers around a shared vision," said Ad Abel, sales director Europe for DSM Functional Materials. "Our passion is providing unique, high-performance solutions for today's telecommunications providers—and, ultimately, giving them confidence that their networks are 'future-proofed.'"
