STL Unveils Cutting-Edge Fiber Optic Cable at Connected Britain 2025
London, Friday, 26 September 2025.
STL introduced a high-density indoor fiber optic cable with Multi-Core Fiber technology, enhancing connectivity for smart buildings, supporting next-gen applications like AI and 5G.
Revolutionizing Indoor Connectivity with Multi-Core Fiber
The recent unveiling by STL at Connected Britain 2025 marks a significant advancement in optical fiber technology. The new high-density indoor unitube fiber optic cable integrates Multi-Core Fiber (MCF) technology, which incorporates four cores within the same cladding diameter as standard single-mode fibers, maintaining a 250/200-micrometer coating size. This allows the cable to support up to 3,456 fibers without increasing its form factor, effectively quadrupling the data throughput potential compared to traditional fiber technologies [1][2].
Technical Specifications and Features
The STL fiber optic cable is certified under the Construction Products Regulation (CPR) EuroClass Cca-s2, d1, a1, ensuring high fire resistance, a critical feature for protecting infrastructure during fire incidents. The cable also offers advanced security through Quantum Key Distribution (QKD), providing tamper-proof physical and digital encryption. These specifications make it ideal for smart buildings, data centers, and urban infrastructure, where security and high-capacity networks are paramount [1][3].
Comparative Analysis with Existing Technologies
In comparison to existing single-mode fiber technologies, STL’s MCF technology provides a fourfold increase in bandwidth capacity, crucial for supporting next-generation applications like AI and 5G. The compact design of the unitube cable allows for efficient installation in space-constrained environments, positioning it as a superior alternative to traditional fibers that require larger diameters for similar capacities. Furthermore, the cable’s certification under CPR EuroClass Cca-s2, d1, a1 provides an edge in safety and compliance for European markets [1][4].
Market Impact and Future Prospects
STL’s introduction of the high-density MCF cable is poised to significantly impact the European market, where there is a growing demand for efficient and secure data transmission solutions. The cable’s ability to support AI, 5G, and quantum applications aligns with the digital transformation goals of many European cities, making it a strategic choice for urban planners and technology companies. As STL continues to innovate and expand its product offerings, the adoption of MCF technology is expected to accelerate, paving the way for more advanced connectivity solutions [2][5].
