The global corporate race to deploy AI has fueled the need for optical modules that are paired with compute servers. In popular generative AI applications such as ChatGPT, an enormous volume of data requires swift and high-bandwidth transmission between servers. Optical transceivers facilitate high-speed, long-distance data transfer and send data via fiber optics, offering much higher data transmission speeds and bandwidth than traditional cable means. Consequently, optical transceivers play a critical role in data communication between AI servers, ensuring rapid and stable data transfer, and providing efficient data exchange for AI applications.

Faster Transceivers for the Age of AI

Optical transceivers are crucial in developing better AI systems by facilitating the rapid, reliable data transmission these systems need to do their jobs. High-speed, high-bandwidth connections are essential to interconnect data centers and supercomputers that host AI systems and allow them to analyze a massive volume of data.

In addition, optical transceivers are essential for facilitating the development of artificial intelligence-based edge computing, which entails relocating compute resources to the network’s periphery. This is essential for facilitating the quick processing of data from Internet-of-Things (IoT) devices like sensors and cameras, which helps minimize latency and increase reaction times.

400 Gbps links are becoming the standard across data center interconnects, FS are already considering the next steps. LightCounting forecasts significant growth in the shipments of dense-wavelength division multiplexing (DWDM) ports with data rates of 400G, 800G, and beyond in the next five years.

400G Transceiver for Artificial Intelligence (Al) & Machine Learning (ML)

400G transceiver enables high-speed data transfer within data centers, making it possible to move large amounts of data between servers and storage devices quickly and efficiently. This is partticularly important in Al and ML applications, where the processing of large datasets in real time is necessary. With a 400G transceiver, Al and ML systems can operate at faster speeds and process large datasets, leading to more accurate results and better insights.

Advantages of Deploying a 400G Network

  • Higher Bandwidth: 400G optical transceivers provide higher bandwidth than their predecessors, allowing for faster and more efficient data transmission.

  • Faster Speeds: With data rates up to 400Gbps, 400G transceivers can support high-speed data transmission, which is especially useful for applications that require real-time data processing and analysis.

  • Lower Power Consumption: 400G is a more energy efficient option than 100G, as it consumes less energy per unit ofinformation transmission. This not only meets the need for energy conservation but also aligns with the growing emphasis on environmental protection.

What scenarios can 400G optical modules be used in?

HPC Data center Meta

  • High Performance Computing (HPC): The use of 400G optical transceivers in HPC applications has been gaining traction due to their high bandwidth capabilities and low latency. In particular, they are used in InfiniBand and Ethernet applications to improve the performance of HPC systems.

  • Data Centers and Cloud Computing: With the rise of cloud computing and big data analytics, there is a need for fast and reliable communication between servers and storage devices. Data centers are often distributed across multiple locations, and there is a need for high-speed interconnects between them to transfer data. 400G optical modules can provide the required bandwidth and low latency for these applications.

  • Meta or Metaverse: 400G optical transceiver can apply in transmitting high-qualityand low-latency data for virtual and augmented reality experjences. These applications require high-speed and low-latency data transmission to ensure that the virtual or augmented reality experience is smooth and without any lag.

Conclusion

Due to the increasing demand for bandwidth in ultra-large-scale data centers, it has become thebest solution to enhance system performance and reduce bardwidth costs. The emergence of 5G networks is expected to further drive the market value of 400G transceivers. The development prospects of 400G optical modules are vast, and they will provide better datatransmission speed and energy consumption in the future.
