STL showcases high-density Unitube Indoor Optical Fibre Cable with Multi-Core Fiber at Connected Britain 2025
The launch of a new, advanced product that is certified for high safety and performance in critical indoor environments (such as data centres) strengthens STL's product portfolio and addresses growing market demands, potentially contributing to future revenue and market share in key segments.
The company announced the showcase of an advanced, high-density optical fibre cable with significant features like superior security, 4x bandwidth potential, and CPR certification, indicating a strong technological advancement and market relevance for future-ready networks.
* Sterlite Technologies Limited (STL) showcased its advanced Unitube Single Jacket Indoor Fibre Optic Cable with 4-core Multi-Core Fiber (MCF) at Connected Britain 2025 on 24 September 2025. * MCF technology packs 4-cores into the same cladding diameter as standard single-mode fibre, maintaining a coating size of 250/200 micrometres. * STL is among the first companies to demonstrate real-world deployments of MCF technology, covering underground and duct networks, with a complete ecosystem of fibres, cables, and termination solutions. * The newly developed Unitube Single Jacket Indoor Fibre Optic Cable with MCF is engineered for both performance and safety in demanding indoor environments. * It is certified under the Construction Products Regulation (CPR) EuroClass Cca-s2, d1, a1, ensuring a high level of fire resistance to protect critical infrastructure during fire incidents. * This cable is ideally suited for Data Centres, campus networks, commercial buildings, and other indoor installations that require high-capacity data transfer and compliance with stringent fire safety standards. * Key features of STL Unitube Single Jacket Indoor Fibre Optic Cable with MCF include: * Superior Security: Quantum Key Distribution (QKD) for Physical & Digital tamper-evident encryption. * Future-Ready Bandwidth: Supports next-generation applications like AI, 5G, and quantum computing with 4 times the throughput potential of legacy fibres. * Compact Efficiency: Packs multiple cores into a smaller diameter, significantly multiplying fibre count (e.g., 864 fibres with 4 cores result in 3,456 fibres) while boosting capacity without expanding the physical footprint. * High RoI: Provides a secure and scalable network backbone in a single deployment. * Dr. Badri Gomatam, CTO, STL, commented that through continuous innovation and global partnerships, STL is accelerating the adoption of advanced optical technologies. He stated that their Unitube Single Jacket Indoor Optical Fibre Cable with MCF is engineered to meet the ever-growing demands of high-capacity, secure, and future-ready networks, positioning STL to lead the evolution of optical infrastructure.
