STL launches 'India's first' hollow core fibre cable

STL, an optical and digital systems company, has introduced a hollow core fibre (HCF) cable in India, designed for data centre networks and high-frequency transmission environments. The development focuses on reducing latency and supporting higher bandwidth demands in modern data centres, hyperscale facilities, and network infrastructure. Unlike conventional optical fibre, which transmits light through a solid glass core, hollow core fibre uses an air-filled core. This allows signals to travel at higher speeds, with STL stating performance improvements of around 46%, alongside reduced latency and signal loss. Noting that it is the first company to develop and manufacture this type of cable in India, STL says it is expanding its optical connectivity portfolio in response to increasing demand from AI-driven and high-performance computing environments. The cable also incorporates a hybrid design intended to support a range of network requirements. This includes hollow core fibre for low-latency transmission, G.654.E fibre for long-distance, low-loss performance, and G.657.A1 fibre to support flexible deployment across different network types. Hybrid design supports varied network needs The hybrid architecture reflects the growing complexity of data centre and telecoms infrastructure, where operators require a mix of performance characteristics within a single cable system. STL reports that the design supports both high-speed data transmission and broader network coverage, particularly in large-scale or distributed environments. The company also states that it holds more than 780 patents and continues to focus on optical technologies aimed at increasing network capacity and efficiency. Badri Gomatam, CTO at STL, says, "Our R&D focus has always been on solving the most complex challenges of the future. With the launch of [this] Hollow Core Fibre cable, we are providing the 'speed-of-light' infrastructure required for the AI revolution. "This is a defining moment that demonstrates our capability to innovate and empower hyperscalers and data centres on a global scale.” For more from STL, click here.

Data centre cooling in the AI era

During a busy Data Centre World London 2026, Joe from DCNN caught up with Alistair Barnes (pictured above), Global Head of Mechanical Engineering at Colt DCS, to ask how the mechanical engineering discipline is evolving in response to the rapid rise of AI workloads. The two discussed a variety of topics, from the shift towards liquid cooling solutions to the challenge of keeping pace with ever-increasing rack-level power densities. Here, you can read the full Q&A, in which Alistair shares his perspective on where liquid cooling stands today, how Colt DCS's Global Reference Design philosophy shapes its approach to data centre infrastructure, and what he believes remains the industry's toughest unsolved engineering challenge: Liquid cooling, rack densities, and the future of mechanical engineering Joe: Hi, Alistair! So, how is mechanical engineering keeping pace with the shift to higher-density AI workloads? Alistair: Mechanical engineers are keeping pace with higher‑density AI workloads by moving beyond traditional air‑only cooling and rethinking the entire thermal design stack. Instead of simply supplying cold air, they now operate more like system integrators, collaborating closely with IT and facilities teams to cool heat‑intensive components such as GPUs. This includes integrating direct‑to‑chip cold plates, liquid distribution loops, and hybrid cooling systems capable of managing the extreme heat generated by modern AI hardware. Joe: In your opinion, is liquid cooling now a mainstream solution or still a specialist one? Alistair: Liquid cooling is becoming increasingly mainstream, but the industry isn’t yet at a point where it can rely on liquid alone, as air still plays an important role in most deployments. Operators adopting Global Reference Designs (GRDs) now include liquid‑cooling options to support high‑density AI workloads that air alone can’t efficiently manage. As a result, many still use hybrid setups that combine air cooling with liquid where needed. Closed‑loop systems, such as liquid‑to‑chip, circulate coolant in a sealed loop, ensuring near‑zero wastewater and making them practical and sustainable. Joe: Where does mechanical engineering sit in Colt DCS's broader data centre design philosophy? Alistair: Mechanical engineering sits at the core of our design philosophy, supporting our commitment to delivering scalable, efficient, and sustainable data centre solutions. We adopt a GRD, a standardised and repeatable blueprint that accelerates deployment, optimises cost, and maintains consistent quality while remaining flexible enough to meet local requirements. Mechanical engineers play a key role in shaping the GRD, ensuring mission-critical cooling infrastructure and integrating new technologies across sites to support future growth and reliable operations. Joe: What's the hardest engineering problem the industry hasn't solved yet? Alistair: The hardest engineering problem the industry hasn’t solved is keeping pace with the accelerating rise in rack‑level power densities. Liquid cooling is advancing quickly and can manage far more heat than ever before, but single‑rack densities approaching 2MW and beyond are increasing faster than these solutions can be deployed at scale. The real challenge is delivering this capacity sustainably - balancing cooling performance, energy efficiency, and power availability - all while accelerating build timelines to keep up with customer demand.
