• Fire Protection for the next-generation AI Data Center Overhead and Underfloor Pathways

COLUMBIA, S.C., Sept. 10, 2026 /PRNewswire/ -- STL (NSE: STLTECH), a leading connectivity solutions provider for AI-ready digital infrastructure, today announced an update to its data center portfolio with Optical Fiber Nonconductive Plenum (OFNP) US certification for 48 to 576F Intermittently Bonded Ribbon (IBR) pre-terminated assembly portfolio. These factory-built cable assemblies are critical to support the AI-led Data Center market requirements with connectors installed, polished, and tested for high performance, preventing the need for field splicing and equipment resulting in fast installation and lowered cost.

With this certification, STL is now among the global AI-ready infrastructure providers for NFPA 262-qualified indoor cable assemblies. The Plenum certified cable assembly portfolio is purpose-built for indoor applications, targeting specialised deployment inside hyperscale, colocation, and enterprise data center containment zones. Optimised for tight routing environments, these cables enable operators to scale bandwidth within restricted duct spaces without compromising safety compliance.

"As AI workloads push the boundaries of data center design, the physical layer must evolve to meet unprecedented density and safety demands," said Dr. Badri Gomatam, CTO, Optical Networking Business, STL. "Achieving this plenum certification for our indoor IBR cable family is a testament to STL's engineering excellence and our commitment to being the partner of choice for the world's largest hyperscalers. We are proud to deliver solutions that not only power the AI revolution but do so with the highest standards of safety and reliability."
