STL Unveils Groundbreaking Cable Technology at Connected Britain 2025

On September 24, 2025, at the Connected Britain 2025 event, STL (NSE: STLTECH), a leader in optical and digital solutions, presented its cutting-edge Unitube Single Jacket Indoor Fibre Optic Cable, incorporating Multi-Core Fiber (MCF) technology. This advanced cable promises to meet the increasing demand for high-capacity networking solutions in various sectors, including data centers and commercial buildings.

What Makes MCF Technology Stand Out?

The Multi-Core Fiber technology uniquely integrates four cores into a cladding diameter that is equivalent to traditional single-mode fiber (SMF). This innovation maintains a coating size of 250/200 micrometers, ensuring that the cable remains compact while vastly increasing its capacity. By fitting multiple cores into a smaller diameter, the Unitube cable allows for an exponential increase in fiber count without requiring additional space—offering the potential for up to 864 fibers with four cores, equating to an impressive 3,456 fibers.

Certification and Safety Standards

STL has engineered the Unitube Single Jacket Indoor Fibre Optical Cable with MCF not only for peak performance but also for enhanced safety in challenging indoor environments. The cable has been certified under the Construction Products Regulation (CPR) EuroClass Cca-s2, d1, a1. This certification guarantees a high level of fire resistance, prioritizing the protection of critical infrastructure in case of fire incidents. Such features make this cable an ideal choice for environments that must adhere to stringent fire safety standards.

Future-Ready for Next-Generation Applications

One of the most notable features of STL's Unitube Indoor Optical Fibre Cable is its support for next-generation applications. The cable is designed to provide four times the throughput potential of legacy fiber optics, ready to accommodate demands from upcoming technologies like AI, 5G, and quantum computing. Additionally, the cable supports superior security measures, including Quantum Key Distribution (QKD), which offers a physical and digital tamper-evident encryption mechanism.

Expanding Ecosystem and Seamless Integration

To complement its advanced fiber solutions, STL has developed optical distribution units and connectivity solutions that seamlessly integrate with existing network architectures. This comprehensive ecosystem is set to facilitate smoother deployments and upgrades, ensuring that organizations can transition to more advanced technologies with minimal disruption.

Dr. Badri Gomatam, CTO of STL, commented on the introduction of the new fibre, stating, "Through continuous innovation and global partnerships, STL is accelerating the adoption of advanced optical technologies. Our Unitube Single Jacket Indoor Optical Fibre Cable with MCF has been engineered to meet the ever-growing demands of high-capacity, secure, and future-ready networks. We take pride in leading the evolution of optical infrastructure that powers next-generation applications."

Conclusion

The unveiling of STL's Unitube Indoor Optical Fibre Cable at Connected Britain 2025 marks a significant advancement in the realm of optical solutions. This innovative product not only promises exceptional performance but also adheres to rigorous safety standards essential for indoor installations. With continuous efforts toward global standardization and real-world implementations, STL is positioning itself as a frontrunner in shaping the future landscape of optical technology and connectivity solutions.
