Sterlite Technologies Inc (STI), the U.S. arm of global optical networking leader STL, has launched a cutting-edge 864-fiber Intermittently Bonded Ribbon (IBR) cable, setting a new benchmark in fiber density and compact design for hyperscalers and data center operators across the United States. The new Celesta IBR Cable features an ultra-slim profile with a diameter of just 11.7 mm, making it the slimmest 864F cable available globally. Engineered for high-efficiency installation, it’s optimized for jetting into standard 14mm inner diameter ducts and has achieved a remarkable jetting distance of over 4,700 feet (1,500+ meters) in under 20 minutes.
Built with bend-insensitive HD G.657.A2 200-micron fiber, this cable delivers exceptional installation performance and durability, even in challenging conditions. It also adheres to ICEA 122-744 standards and is GR-20 compliant, ensuring compatibility with micro subducts of 14/18 mm and long-term reliability.
As data demand surges, hyperscalers require infrastructure that supports massive data transfer with minimal latency, all within limited physical space. The Celesta IBR cable addresses this need by combining high fiber counts with a compact form factor and efficient mass fusion splicing capabilities.
The cable’s innovative intermittent ribbon bonding design enables high-density fiber packing, which is essential for modern high-bandwidth applications. This design supports rapid and efficient deployment, making it ideal for environments that demand both performance and scalability.
Engineered for versatility, the cable is well-suited for a range of critical network infrastructure scenarios—including data centers, high-capacity network interconnects, equipment cabinet wiring, and outside plant installations. Its compact form factor and ease of installation make it a strong fit for both current needs and future network expansion.
This launch is part of STL’s broader IBR cable portfolio, ranging from 12F to an industry-leading 6912F, with more innovations underway. Over the past five years, the company has delivered more than 10 million fiber kilometers across North America and Europe.
STL was a pioneer in introducing IBR cable technology in India and continues to scale globally with 10 manufacturing facilities across North America, Europe, and Asia. The company’s North American headquarters and advanced manufacturing operations are based in Lugoff, South Carolina.
Dr Badri Gomatam, Chief Technology Officer at STL, commented “The Celesta IBR cable reflects our dedication to precision engineering and customer-driven innovation. By achieving unmatched fiber density in such a slim form, we’re enabling hyperscalers and data center operators to scale efficiently while future-proofing their network infrastructure.”
STL continues to focus on building end-to-end solutions for high-capacity networks across 5G, fibre-to-the-home (FTTx), rural connectivity, and enterprise deployments. The expansion into advanced data centre products further reinforces its position as a key enabler of India’s and the world’s digital transformation.
