GPUs aren't the only things carrying the AI building. In June, JPC Connectivity – a Taiwanese manufacturer of connectors, cabling, and interconnection solutions for data centers – announced it had achieved its highest monthly revenue ever, fueled by relentless demand for AI infrastructure.

The figure is a litmus test. While the industry's attention stays locked on graphics processors, far less glamorous components are experiencing explosive growth. Every server rack dedicated to training or inference of LLMs is not an island: modern clusters demand high-bandwidth, low-latency interconnects – InfiniBand, NVLink, high-speed Ethernet – and each link depends on cables and connectors capable of sustaining hundreds of gigabits per second without signal degradation. JPC, which supplies OEMs and integrators, has become a bellwether of AI fever.

The race isn't just for cloud titans. More and more organizations are evaluating on-premise deployment of LLMs for data sovereignty, latency control, and TCO. JPC's success, however, signals that pressure is spreading across the entire supply chain: production capacity for high-performance connectors is finite. While hyperscalers book volumes months in advance, anyone planning an on-premise cluster today risks competing for the same supplies. The queue for connectivity has already started.

The paradox is sharp. The growth in on-premise AI demand is fueled precisely by the need to keep data and latency under control, but the ability to build those data centers could be held back by components few would consider critical. It's not just a cost issue – it's a lead time issue. Enterprises building air-gapped environments or GPU clusters for fine-tuning must factor in that the supply chain is strained on all fronts, not only on chips.

The shift toward 800G and faster interconnects requires generational leaps in connector design, with increasingly stringent tolerances and materials. JPC, which invests in R&D for these standards, is well positioned, but its record growth is also a symptom of a market outpacing supply adjustment. For businesses, the signal is clear: technological sovereignty also depends on the availability of a well-made cable.
