NADDOD 400G/800G Optical Module Boosts AI Computing Power Acceleration

NADDOD Neo Switch Specialist Jan 29, 2024

The demand for computing power continues to grow with the application of large-scale AI training, generation algorithms, and data inference techniques. In this process, high-speed optical modules serve as the carrier for interconnecting devices within data centers. Traditional 100G and 200G modules are no longer sufficient to meet the increasing demand for computing power. As a result, the upgrade to 400G, 800G, and even higher-capacity optical modules has been accelerated.

 

According to LightCounting data, the period from 2020 to 2022 is a rapid ramp-up period for 400G optical modules. At the OFC exhibition in 2023, there was a proliferation of 800G optical module products, indicating further industry attention to 800G products. It is expected that the volume production of 800G products will begin in 2022 and will start dominating the market from the end of 2025.

As an essential component of optical communication, optical modules are core elements for optoelectronic conversion in data center network connections.

 

The transmission rate of a 400G optical module is 400Gbps, designed to meet the needs of network markets ranging from 10G, 25G, 40G, 100G, 400G, and even 1T. It plays a crucial role and has a significant impact on building 400G network systems. Its primary function is to increase data throughput and maximize the bandwidth and port density of data centers.

 

800G optical module is a type of optical module with a transmission rate of 800Gbps (gigabits per second). It can double the network throughput, greatly enhancing the data transmission rate and processing capacity of data centers and cloud computing. It is primarily used to improve the bandwidth and port density of data centers, reduce costs and energy consumption, and enhance network stability and reliability.

 

The future prospects of 800G optical modules are very promising. With the increasing demand in the data center and cloud computing markets, along with the development of the Internet of Things (IoT) and the widespread adoption of 5G networks, the need for high-speed, high-capacity networks will continue to grow. This will further drive the market demand for 800G optical modules. These modules are capable of meeting the requirements of these emerging technologies and applications, providing higher data transmission rates and increased network capacity. As a result, the deployment of 800G optical modules is expected to expand as the demand for faster and more efficient data transmission continues to rise.

 

Currently, there are various technologies being used in the development of 800G optical modules, including PAM4 (4-level pulse amplitude modulation), DML (directly modulated laser), and EML (external cavity modulated laser), among others. These technologies are continuously being improved and enhanced, which will further improve the performance and reliability of 800G optical modules.
