STL Unveils State-of-the-Art Indoor Optical Fiber Cable

On September 25, 2025, during the Connected Britain 2025 conference, STL (Sterlite Technologies Ltd), a leader in optical and digital solutions, presented its revolutionary indoor Unitube Optical Fiber Cable featuring Multi-Core Fiber (MCF) technology. This innovative cable signifies a major advancement in fiber optic technology, set to redefine data transmission standards in various high-capacity indoor environments.

What is Multi-Core Fiber (MCF)?

Multi-Core Fiber technology enables four separate cores to be housed within a single standard optical fiber diameter, which typically measures around 250/200 micrometers. This integration allows for a significant increase in bandwidth capacity without enlarging the physical dimensions of the cable, thus maintaining the compactness crucial for modern infrastructure. STL’s MCF cable accommodates up to 864 fibers, amounting to an astonishing capacity of 3,456 fibers when effectively utilized.

Key Features and Benefits

The advantages of STL's indoor Unitube Optical Fiber Cable equipped with MCF are manifold:
1. Enhanced Security: Incorporating Quantum Key Distribution (QKD) technology facilitates unbreakable physical and digital encryption, ensuring data security for critical infrastructure.
2. Next-Generation Bandwidth: Capable of supporting cutting-edge applications like artificial intelligence and quantum computing, the cable boasts a throughput potential that is four times greater than traditional fiber options.
3. Compact Efficiency: By consolidating multiple cores into a smaller diameter, the MCF cable not only increases fiber count but also maximizes capacity without bulk.
4. High Return on Investment: This single deployment leads to a secure, scalable backbone network, optimizing infrastructure investments.

A Commitment to Safety

STL’s innovation is not solely about performance; it is also deeply rooted in safety. The new cable has been certified under the Construction Products Regulation (CPR) standards, specifically aiming for EuroClass Cca-s2, d1, a1. This classification guarantees a high level of fire resistance, making the cable suitable for critical installations in data centers, campus networks, commercial buildings, and other indoor settings where data transmission must comply with rigorous fire safety standards.
