Application of AI Server Optical Module

Optical modules convert electrical signals into light to move data quickly and reliably in AI systems, enabling fast and smooth data processing. The rapid growth of Artificial Intelligence (AI) and Machine Learning (ML) workloads demands highly efficient and scalable network infrastructures to support massive data transfer and low-latency communication across Graphics Processing Unit (GPU) clusters. AI Platforms Powered by High-Speed PAM4 DSP-based Optical Connectivity High-speed connectivity is essential for optimal performance in AI platforms. The company's main optical communication modules QSFP-DD, OSFP112, QSFP28 and other high-speed optical modules play a role in this far-reaching industry change.

CPO Optical Module Investment

In early March 2026, Nvidia injected $2 billion each into photonics manufacturers Lumentum and Coherent, securing future production capacity and technology rights for advanced optical components with a total investment of $4 billion. GF's SCALE solution, or Silicon photonics Co-packaged Advanced Light Engine solution, is the industry's first Optical Compute Interconnect Multi-Source Agreement (OCI MSA) capable platform, exceeding the requirements for the OCI MSA's optical interconnect specification for modern AI scale-up. , May 5, 2026 — GlobalFoundries (GF) has introduced an optical module solution for co-packaged optics (CPO). Cignal AI initiates its first quantitative CPO forecast; Over 30 million CPO ports expected to be shipped annually by 2030. Over the coming years, CPO is poised to see a dramatic uptick in demand, as data center operators push to expand the limits of AI.

Optical module plugged into AP panel

An optical module implements optical-to-electrical or electrical-to-optical conversion, and connects to an optical fiber cable for transmitting signals. They enable high-speed connections between active equipment and allow system scalability without the need for full infrastructure replacement. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process.

Can the light emitted by the optical module be seen

Self-loop inspection: The light emitted by the multi-mode fiber optical module is visible light, which can be observed with the naked eye (do not look directly at the light-emitting port). Subsequently, the driver semiconductor laser (LD) or light-emitting diode (LED) emits modulated optical signals at the corresponding rate. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. Its fundamental role is to bridge the gap between electrical equipment and optical fibers.

Optical module material PCB

Optical module PCB technology is evolving rapidly to meet the extreme demands of AI data centers and high‑speed networks. 6T, next‑generation optical modules require higher density, advanced materials, innovative thermal management, and new architectures. In simple terms, they convert electrical signals from devices like routers, switches, and servers into light signals that travel through fiber optic cables. The Printed Circuit Board (PCB) at the heart of these modules is no longer a simple substrate but a highly engineered system. This guide explains the key PCB technologies, materials, manufacturing processes, and cost considerations for 400G and 800G optical modules in 2026.
