As artificial intelligence dominates the collective consciousness, rapid advancements are unfolding at breakneck speed. To sustain this momentum, companies must prioritize robust infrastructure capable of handling the computationally demanding AI applications they seek to deploy. That is what we name Microsoft has made a dedication to its clients for AI, demonstrating its commitment to innovation. This dedication transcends mere integration of partner-developed hardware into its datacenters; instead, Microsoft collaborates with partners, sometimes independently, to pioneer cutting-edge technology that fuels AI solutions.
Considered one of the key applied sciences showcased at Microsoft Ignite in November was Hole Core Fiber (HCF), a cutting-edge optical fibre technology poised to revolutionize Microsoft Azure’s global cloud infrastructure by delivering unparalleled network quality, reduced latency and secure data transmission.
Transmission by air
HCF know-how was designed to meet the surging demands of workloads like AI and accelerate international latency and connectivity. By leveraging a proprietary design where light propagates through an air core, HCF offers significant advantages over traditional fibre constructed with a solid core of glass.
The HCF construction’s unique feature is its nested tube design, which effectively minimizes unwanted light leakage while keeping the beam focused along a precise path through the core.
As HCF material travels significantly faster through air than conventional glass, boasting a 47% acceleration advantage over commonplace silica glass, it achieves heightened overall speed and reduced latency. What’s the difference between speed, latency, and bandwidth? While pace measures the rate at which data propagates through a fibre network, community latency refers to the time it takes for information to traverse between two endpoints within that community. To reduce latency, one must accelerate response times. Bandwidth refers to the amount of information exchanged between entities within a network, encompassing both transmission and reception capacities. Two cars, traveling in tandem from Point A to Point B, both departing at precisely the same moment. The primary vehicle represents a Single-Mode Fiber (SMF), whereas the secondary one exemplifies a Higher-Capacity Fiber (HCF). Automobiles carry a maximum of four passengers, while vans can accommodate up to sixteen individuals at once. Automobiles can achieve vastly diverse speeds, with vans generally outpacing cars. Given that the van’s travel time to Level B is significantly reduced, it will likely arrive at its destination earlier, thereby illustrating a notable decrease in latency.
For more than five decades, the industry has consistently made incremental advancements in silica fibre technology. Despite moderate gains, the optimistic signs are tempered by significant limitations stemming from silica loss.
A significant achievement for HCF’s expertise was marked in early 2024, with a breakthrough in optical fibre technology that saw the lowest ever recorded attenuation at 1550nm wavelength, surpassing even the exceptional performance of pure silica core single-mode fibre. 1
Compared to single-mode fibre (SMF), hollow-core fibre (HCF) offers a unique combination of benefits, including low attenuation, increased launch energy handling, broadened spectral bandwidth, and enhanced signal integrity and data security.
The necessity for pace
As I log into my favorite online game, a rush of excitement courses through my veins. The high-speed nature of the sport demands swift reflexes and instantaneous decision-making. When leveraging high-speed connectivity for low-latency performance, your on-screen actions are instantly transmitted to both the game server and your friends, enabling real-time reactions and a seamless gaming experience. If you encounter excessive latency issues, a noticeable delay may arise between your actions and the game’s response, compromising your ability to keep pace with the rapid gameplay. Regardless of whether you’re experiencing a scarcity of crucial movement moments or struggling to keep pace with peers, lag can be infuriatingly frustrating and has the potential to severely impede your gaming experience. By leveraging advancements in AI, the models can process knowledge more efficiently, leveraging low-latency and high-speed connectivity to render decisions with increased speed and precision.
Decreasing latency for AI workloads
By leveraging Hyper-Converged Fabric (HCF), organizations can significantly boost the efficiency of their AI infrastructure in several ways. Firstly, HCF enables a software-defined architecture that simplifies the deployment and management of complex AI workloads, thereby reducing administrative overheads and accelerating time-to-value. Secondly, its integrated networking capabilities provide a seamless and secure data pipeline for AI applications, ensuring high-speed data transfer and minimizing latency. Artificial intelligence workloads refer to computational tasks that involve processing vast amounts of data using machine learning algorithms and neural networks. These duties encompass a range of tasks, including picture recognition, natural language processing, PC vision, and speech synthesis, among others.

Steps can involve the exchange of information with diverse sources, such as cloud servers, edge devices, or other nodes within a distributed system. The tempo and caliber of community interactions significantly impact the swiftness and accuracy with which information is disseminated and processed. If a community proves sluggish or unreliable, this could potentially set off a chain reaction of delays, errors, or outright failures within the AI workflow. Without proper planning and execution, this initiative risks culminating in inefficient processes, squandered resources, and flawed results. These fashion models typically require substantial processing power, lightning-fast networking, and storage to efficiently handle increasingly complex workloads featuring billions of parameters; consequently, low latency and high-speed connectivity can significantly accelerate model training and deployment, ultimately boosting efficiency, accuracy, and driving AI advancements.
Simplifying global deployment of AI applications
High-performance networking and ultra-low latency are crucial enablers for AI applications demanding real-time or near-real-time responsiveness, much like autonomous vehicles, video streaming services, online gaming platforms, and smart devices. These mission-critical workloads require real-time processing and decision-making in milliseconds or seconds, implying that even the slightest delay or disruption would be unacceptable within the community.

Heterogeneous Compute Fabric (HCF) expertise can significantly accelerate the efficiency of Artificial Intelligence (AI), providing faster, more reliable, and secure networking for AI models and applications.
Regional implications
Beyond the physical hardware that powers AI applications, lie more profound implications. Datacenter locations are expensive, and the distances between them, as well as those between facilities and customers, have a significant impact on both users and Microsoft Azure as it determines where to build these data centers. As an area becomes increasingly isolated from potential buyers, the model faces a significant hurdle in terms of latency, as data must travel further to and from a central hub.
As the distinction between automotive and vans is applied to community dynamics, the harmonious blend of increased bandwidth and accelerated transmission rates enables data exchange between entities to occur at least three times faster. Alternatively, HCF enables communities to achieve a significant expansion of their existing network capacity, potentially increasing transmission distances by up to 50%, without compromising overall network efficiency. Ultimately, you may push even further beyond traditional SMF boundaries in terms of latency, leveraging more knowledge. This development holds significant implications for Azure customers, allowing them to optimize their setups without sacrificing latency or efficiency by eliminating the need for datacentre proximity.
