ADIA backs TeraHop optics expansion

Abu Dhabi Investment Authority has taken part in a capital raise by TeraHop, a Singapore- and Thailand-based supplier of high-speed optical transceivers used in data centres, strengthening its exposure to one of the most critical layers of artificial intelligence infrastructure.

The investment was made through a wholly owned ADIA subsidiary. The value of the Abu Dhabi investor’s participation was not disclosed. TeraHop, a subsidiary of Zhongji Innolight, plans to use the proceeds to expand its manufacturing footprint, improve operational capacity and continue funding research and development.

TeraHop operates research and development and sales centres in Singapore and the United States, while its production base spans Thailand and Taiwan. The company supplies optical transceivers that enable high-speed data transmission inside and between data centres, a segment that has gained strategic importance as cloud providers, AI developers and telecom operators upgrade networks to support heavier computing workloads.

Hamad Shahwan Aldhaheri, Executive Director of ADIA’s Private Equities Department, said the transaction reflected the fund’s focus on backing high-quality companies with long-term growth prospects. He said TeraHop was well placed to play a larger role in the data centre infrastructure supply chain and deliver attractive risk-adjusted returns.

The deal places ADIA deeper into a fast-growing but technically demanding part of the digital infrastructure chain. Optical transceivers are small but essential components that convert electrical signals into optical signals and back again, allowing servers, switches and storage systems to move data at high speed with lower latency. As AI models grow larger and data centres become denser, demand has shifted from 100G and 400G products towards 800G and next-generation 1.6T modules.

Zhongji Innolight, listed in Shenzhen, is among the major global suppliers of high-end optical communication modules. Its products serve cloud computing data centres, data communications, 5G wireless networks and telecommunications transmission networks. The company has benefited from surging orders tied to AI infrastructure, where hyperscale data centre operators are racing to increase bandwidth and reduce bottlenecks inside server clusters.

The TeraHop investment also highlights a broader shift in technology supply chains across Asia. Manufacturers of advanced components are expanding production outside mainland China to manage trade risks, customer diversification requirements and geopolitical pressures. Thailand, Taiwan and Singapore have become important nodes in this reconfigured supply chain, offering proximity to electronics ecosystems, export-oriented manufacturing capacity and access to global customers.

For Abu Dhabi, the transaction fits a wider strategy of deploying sovereign capital into sectors that sit at the intersection of technology, logistics, energy and long-term infrastructure demand. ADIA, established in 1976, invests funds on behalf of the Government of Abu Dhabi through a globally diversified portfolio. Its private equities strategy has increasingly targeted companies positioned to benefit from structural shifts rather than short-cycle market momentum.

Data centre infrastructure has become a major investment theme for Gulf-based capital. The rapid expansion of AI computing has increased demand for power, cooling, fibre connectivity, semiconductor packaging, networking equipment and specialised components. Optical modules are a less visible part of that ecosystem, but their importance has risen as data movement becomes a limiting factor in AI performance.

TeraHop’s expansion plans suggest a focus on scale as well as technological depth. Higher-speed transceivers require precision manufacturing, advanced testing and close coordination with data centre equipment makers. The move from 400G to 800G and 1.6T products also raises requirements for power efficiency and thermal performance, two areas that are central to reducing operating costs in large-scale facilities.

The capital raise comes as investors reassess the depth of the AI infrastructure cycle. While valuations across parts of the technology supply chain have climbed sharply, demand from cloud service providers remains strong, driven by model training, inference workloads and enterprise adoption of generative AI tools. At the same time, concerns persist over concentration risk, pricing pressure and the possibility that rapid capacity additions could outpace end-user demand in selected segments.
