STL Launches Plenum-Rated Fiber Trunk Assemblies for AI Data Center Connectivity
Sterlite Technologies Limited (STL) has expanded its data center connectivity portfolio with the launch of plenum-rated fiber trunk assemblies designed for next-generation AI data centers.
The company announced on September 10, 2026, that its 48F to 576F Intermittently Bonded Ribbon (IBR) pre-terminated assembly portfolio has received Optical Fiber Nonconductive Plenum (OFNP) certification in the US.
The certification enables STL to offer indoor fiber connectivity solutions designed to meet stringent fire-safety requirements for AI-driven data center environments.
STL Strengthens Its AI Data Center Portfolio
The rapid growth of artificial intelligence is driving demand for high-density data centers with significantly higher bandwidth requirements.
As AI workloads become more intensive, data center operators need connectivity infrastructure that can support high bandwidth while also meeting safety and installation requirements.
STL said its newly certified fiber trunk assemblies are designed specifically for these requirements.
The products are intended for indoor deployment in:
- Hyperscale data centers
- Colocation facilities
- Enterprise data centers
- Data center containment zones
- Overhead and underfloor pathways
NFPA 262 Compliance
A key development is STL’s achievement of NFPA 262 qualification for its indoor cable assembly portfolio.
The certification applies to STL’s Optical Fiber Nonconductive Plenum (OFNP) portfolio.
Plenum-rated cables are designed for installation in air-handling spaces where fire and smoke performance requirements are particularly important.
For data center operators, this can be an important consideration when deploying large volumes of fiber connectivity inside buildings.
48F to 576F Fiber Portfolio
STL’s newly certified portfolio covers 48 to 576 fiber-count Intermittently Bonded Ribbon (IBR) pre-terminated assemblies.
The factory-built assemblies come with connectors already installed, polished and tested.
This approach can reduce the need for field splicing during installation.
According to STL, the pre-terminated design can help deliver:
- Faster installation
- Reduced field splicing requirements
- Lower installation complexity
- High-performance connectivity
- Better suitability for high-density environments
Designed for High-Density AI Data Centers
AI data centers are increasingly moving toward higher-density network architectures.
This creates challenges in routing large amounts of fiber through restricted spaces.
STL said its plenum-certified assemblies are optimised for tight routing environments, allowing operators to scale bandwidth within restricted duct spaces while maintaining safety compliance.
This makes the product particularly relevant as hyperscalers and other large data center operators expand AI infrastructure.
Management Commentary
Dr. Badri Gomatam, CTO, Optical Networking Business, STL, said that AI workloads are pushing data center designs toward unprecedented density and safety requirements.
He said the company’s plenum certification for its indoor IBR cable family demonstrates STL’s engineering capabilities and its focus on serving global hyperscalers.
Why This Announcement Matters
The announcement comes against the backdrop of rapidly increasing investment in AI infrastructure and data centers.
AI applications require significant computing power, which in turn increases the need for high-speed networking infrastructure connecting servers, storage systems and other data center equipment.
For connectivity companies such as STL, this creates opportunities across the broader AI infrastructure value chain.
The company’s latest product certification could therefore strengthen its ability to participate in projects where indoor fiber connectivity must meet stringent fire-safety standards.
STL’s Global Connectivity Business
Sterlite Technologies provides connectivity solutions for digital infrastructure, including:
- AI-ready infrastructure

Its customers include data center and cloud companies, telecom operators, internet service providers and large enterprises.
What Investors Should Watch
For investors tracking STLTECH, the latest announcement is strategically relevant because it strengthens STL’s positioning in the growing AI data center connectivity market.
However, the announcement is primarily a product and certification update. It does not disclose a specific order value or immediate revenue contribution from the newly certified products.
Investors should therefore monitor future developments such as:
- New AI data center orders
- Hyperscaler customer wins
- Data center revenue growth
- Order book and pipeline developments
- Margin improvement
- Capacity utilisation
- Expansion of STL’s AI infrastructure portfolio
Bigger Picture: AI and Data Center Infrastructure
The expansion of AI is creating demand not only for GPUs and computing systems but also for the underlying physical infrastructure.
Fiber connectivity is a critical component of this infrastructure because large-scale AI facilities require high-speed communication between computing, networking and storage systems.
STL’s move into plenum-rated fiber assemblies positions the company to address one of the specialised requirements of indoor AI data center deployments.
Conclusion
Sterlite Technologies has strengthened its AI-ready data center portfolio with US OFNP certification for its 48F to 576F Intermittently Bonded Ribbon pre-terminated fiber assemblies.
The company’s NFPA 262-qualified solutions are designed for high-density indoor applications across hyperscale, colocation and enterprise data centers.
While the announcement does not include a specific order win or financial guidance, it represents another step in STL’s strategy to participate in the expanding AI, cloud and data center infrastructure market.
Investors should watch whether the new certified products translate into customer wins, data center contracts and incremental revenue over the coming quarters.
