As AI models scale in complexity and volume, they are placing extraordinary demands on the connectivity fabric that links accelerators, memory, storage and system components. Modern hyperscale environments depend on high bandwidth, low latency and energy efficient interconnects, and these requirements are accelerating innovation across signalling speeds, optical technologies and thermal engineering. Molex’s predictions for 2026 reflect a clear industry shift toward faster, denser and more resilient infrastructure capable of supporting next generation AI and Machine Learning architectures.

High Speed Interconnects for AI and Machine Learning Architectures

To meet the performance thresholds required by AI workloads, engineers are turning to interconnect solutions that can support extreme signalling speeds. The transition to 224Gbps PAM 4 is well underway, forming the backbone of emerging board level and backplane architectures. At the same time, high speed pluggable I/O connectors supporting 400Gbps and 800Gbps bandwidth are becoming the standard for data centre scalability, with a clear roadmap toward 1.6T performance.

This evolution is driven by the rising complexity of GPU to GPU and AI accelerator communication, where the density and efficiency of interconnects significantly influence training and inference throughput. As AI clusters scale, reliable high speed backplane and board to board connectivity becomes essential to maintain signal integrity and ensure predictable system behaviour across thousands of interconnected devices.

Thermal Management and Energy Efficiency Barriers

Thermal constraints remain one of the most significant bottlenecks in scaling AI infrastructure. High performance servers and accelerators consume vast amounts of energy, generating heat levels that exceed the capabilities of traditional air cooling solutions. As a result, the industry is accelerating investment in liquid cooling technologies, including:

• Direct to chip cooling for efficient heat removal at the source
• Immersion cooling approaches for high density rack designs
• Passive components that enhance airflow and complement active cooling strategies

These advancements are essential for enabling 224Gbps signalling and supporting the growth of generative AI applications, where thermal performance directly influences compute throughput, energy efficiency and long term system reliability.

Co Packaged Optics (CPO) for Scale Up Architectures

With hyperscale environments transitioning toward increasingly dense and power sensitive architectures, Co Packaged Optics (CPO) is emerging as a pivotal technology. CPO integrates optical engines directly at the chip edge, dramatically increasing bandwidth density while reducing electrical signal loss and overall power consumption. These benefits make CPO an ideal solution for GPU to GPU interconnectivity in AI rich environments where latency, throughput and efficiency are critical.

As AI clusters expand, CPO is expected to play a central role in eliminating the distance and power barriers associated with traditional electrical links. Molex anticipates continued industry focus on CPO as hyperscalers seek to futureproof their infrastructure against the explosive bandwidth demands of next generation AI and Machine Learning workloads.

Specialty Fibre Optics for MedTech, Aerospace and Defense

Beyond data centre environments, specialty fibre optics are transforming connectivity in MedTech, aerospace and defence applications. These fibres deliver high precision, EMI immune communication in systems that depend on accuracy, safety and reliability. No wider than a human hair, these optical links underpin technologies such as:

• High resolution imaging equipment including MRI and CT scanners
• Laser based therapeutic systems used in non invasive medical procedures
• Satellite and spaceborne platforms requiring long distance, low loss data transmission

Because these applications often function in harsh or isolated environments, maintaining signal integrity over long distances is essential. The adoption of specialty fibre optics reflects a broader push for lightweight, interference free and highly reliable connectivity solutions in mission critical sectors.

Miniaturisation, Electrification and Modular Architectures Across Key Industries

Why Next Generation Systems Depend on Smaller, Lighter and More Flexible Connectivity

The acceleration of AI enabled technologies is reshaping requirements for connectors and interconnect systems across multiple industries. As products become smarter, more compact and more power intensive, engineers are prioritising solutions that deliver rugged performance in smaller form factors, support electrified platforms and align with emerging modular standards. Molex’s 2026 predictions highlight how these trends are converging to influence design decisions in automotive, aerospace, medical and industrial environments.

Rugged Miniaturised Connectors Across Consumer, Industrial and Medical Markets

Historically, rugged miniaturised connectors were most heavily used in automotive, aerospace and defence platforms where vibration, temperature extremes and mechanical stress demanded highly durable designs. Today, the same expectations for reliability and environmental resilience have expanded into a wider set of markets driven by AI and digitalisation.

Wearables, medical devices and industrial systems increasingly rely on compact, lightweight and robust connectors capable of withstanding continuous movement, frequent user interaction and, in some cases, invasive or clinical environments. Examples include:

• Consumer wearables such as smartwatches and fitness trackers
• Industrial equipment including warehouse robotics, touchscreen HMIs and sensor arrays
• Medical devices such as endoscopes, insulin pumps and next generation health monitors

This shift underscores a growing sector wide expectation that even the smallest devices must deliver long term reliability without compromising on power or data performance.
