1. Introduction

With the rapid development of AI computing infrastructure, optical communication technology has become a core driving force in advancing data centers, high-performance computing (HPC), and cloud computing. As a global leader in fiber optic products and WDM system solutions, HTF holds a significant position in the industry due to its strong R&D capabilities and technological expertise. However, as the new generation of switches evolves rapidly, optical module speeds continue to increase, and market competition intensifies, HTF faces not only vast market opportunities but also unprecedented challenges.

2. The Key Role of Optical Modules in AI Computing Infrastructure

Optical modules are one of the core components of optical communication networks. Their primary function is to convert optical and electrical signals, enabling high-bandwidth and low-latency data transmission in data centers, backbone networks, and metropolitan area networks. In AI computing infrastructure, the demand for optical modules primarily arises from high-speed interconnections between servers and switches, as well as between switches, which directly correspond to switch architectures and port speeds.

In recent years, the scale of AI training models has grown exponentially, significantly increasing the demand for data throughput. AI computing clusters require high-speed optical modules to achieve low-latency, high-concurrency data exchange, supporting large-scale distributed computing tasks. For example, mainstream AI training clusters today typically consist of thousands of servers, and inter-server communication speeds must reach at least 400Gb/s or higher to support the synchronous updating of massive model parameters during training. To meet this demand, optical modules have evolved from traditional 10G and 25G speeds to 100G, 400G, and even towards 800G and 1.6T, addressing the data transmission challenges brought by the explosive growth of AI computing power.

Regarding switch interconnects, the competition between InfiniBand and Ethernet solutions has further driven the evolution of optical modules. The NVIDIA Quantum-X800 InfiniBand switch adopts a 200Gb/s SerDes design per channel, requiring 72 units of 1.6T optical modules for its 144 800Gb/s ports, providing ultra-low-latency, high-speed interconnects for AI data centers. Similarly, AI clusters based on 400G/800G Ethernet architectures also require high-throughput optical modules to support large-scale AI inference and training tasks. The upgrade of optical modules not only demands higher per-port speeds but also breakthroughs in power consumption, heat dissipation, and packaging technology to reduce overall data center energy consumption and operational costs.

Furthermore, the packaging and transmission distance of optical modules are critical factors in AI infrastructure interconnects. Currently, intra-data center connections primarily use short-distance optical modules, such as 400G DR4 and 800G DR8, while relying on silicon photonics technology to reduce costs. However, as data centers expand, Data Center Interconnect (DCI) demand is rising, increasing the need for longer transmission distances in optical modules. For instance, coherent optical technology enables optical modules to support transmission distances of 80km or more, facilitating efficient connections between different data centers. For HTF, this presents a key opportunity to expand into the high-end optical module market. If HTF can take the lead in launching long-distance, high-bandwidth transmission solutions for 1.6T and higher-speed optical modules, it will capture a larger share of the AI data center market.

In addition to speed improvements, the intelligence and manageability of optical modules are crucial for optimizing AI data center operations. The new generation of optical modules is gradually integrating digital signal processing (DSP), adaptive tuning, and status monitoring functions to enhance network reliability and visibility in operations. Intelligent optical modules can monitor link conditions in real time and dynamically adjust through software-defined networking (SDN) architectures to optimize data flow and reduce network congestion. This trend makes optical modules not only critical components for data transmission but also integral to the intelligent management of AI infrastructure.
