Major breakthrough in domestic high-end optical communication chips, Changguang Huaxin releases five new products

To meet the growing demand for AI computing power, on March 14, Changguang Huaxin held an online new product launch for optical communication chips, releasing five market-leading high-end optical communication chip products: 200G PAM4 EML, 200G PAM4 PD, 100G PAM4 PD, 70mW CWDM4 CW Laser, and 100G PAM4 VCSEL (SR). Among them, The 200G EML supporting product and 70mW CWDM4 CW Laser are products publicly released for the first time by domestic manufacturers, representing a major technological breakthrough in domestically produced high-end optical communication chips, filling the supply chain shortage and localization gap of high-end chips in China.

AI model scale continues to expand

Computing power demand grows exponentially

In recent years, with the rapid development of artificial intelligence technology, pre-trained large models represented by the GPT series and DeepSeek have made significant breakthroughs in natural language processing, computer vision, and other fields, promoting AI's transition from specialized to general use, and the scale of AI models continues to expand. The training and inference of large models require massive computing power support. For example, GPT-3 has 175 billion parameters, and the computing power consumption for a single training run is extremely high. As the number of model parameters increases, the demand for computing power grows exponentially. In addition, AI technology applications continue to expand into fields such as intelligent driving, medical imaging diagnosis, and financial risk prediction, further intensifying the growth in computing power demand.

High-end optical communication chips

Optical communication is the highway of AI data centers

Optical chips break bandwidth bottlenecks, supporting massive interconnection of AI computing clusters

Optical communication chips, with characteristics of "high bandwidth, low latency, and low power consumption," have become key technologies for upgrading AI infrastructure, especially indispensable in ultra-large-scale model training, edge intelligence, and new computing architectures. Their technological evolution (such as lasers, CPO, silicon photonics) will continue to define the ceiling of AI computing power.
