New Product Launch | Changguang Huaxin 100mW CW DFB Optical Communication Chip

01/08

2024

On December 28, 2023, the inaugural Suzhou Optoelectronic Technology Industry Forum was successfully held. The conference focused on the prospects and opportunities of optical communication and optoelectronic technology applications, attracting professional audiences from the upstream and downstream of the communication industry, research institutes, and more.

Changguang Huaxin deeply participated in this event by Xunshi, launching a new 100mW CW DFB high-power optical communication laser chip on site, showcasing the full range of optical communication products, and participating in a roundtable forum to discuss future opportunities and challenges in optical communication chip technology development.

New Product Launch | 100mW CW DFB

Changguang Huaxin's 100mW CW DFB product made its debut at this event, featuring the following characteristics:

1) Higher output optical power: Compared to the industry-standard 70mW light source, it increases by more than 1.5dB. The 400GE DR4 silicon photonics module can achieve this with only one light source, simplifying optical module design and significantly reducing optical module costs.

2) High photoelectric conversion efficiency: Reduces per-bit power consumption, with chip power consumption better than similar products, improving long-term chip reliability. This light source is compatible with scenarios such as 800G/1.6T. Optical interconnection applications, meeting the continuous evolution demands of high-speed rates.

3) Designed for future long-term evolution: This light source is compatible with optical interconnection applications in scenarios such as 800G/1.6T, meeting the continuous evolution demands of high-speed rates.

Roundtable Forum | Discussing Opportunities and Challenges

With the development of AI computing power connections and data centers, optical interconnection as the foundational base, the optical communication and optoelectronic industry chain is ushering in a new phase of intersection and innovation. Artificial intelligence further promotes the widespread application of optical technology in information transmission, data center management, autonomous driving, rail transit, and coal mine monitoring. Facing rapidly evolving optoelectronic technology, the event invited industry experts for a "peak debate" to discuss future opportunities and challenges in optical communication chip technology development.

Changguang Huaxin Deputy General Manager Wu Zhenlin attended the roundtable forum and introduced Changguang Huaxin as an IDM semiconductor laser chip company, outlining the development history and platform planning around the "one platform, one fulcrum, horizontal expansion, and vertical extension" strategic layout. He shared the opportunities and difficulties faced in the intelligent AI era with explosive computing power and optical network demands, as well as the digital China strategic dividend, domestic chip customer onboarding, and volume growth. He introduced the company's mass-produced and mature products in optical communication, as well as the high-power laser chip 100mW CW DFB making its debut at this forum. He also introduced Changguang Huaxin's firm commitment to the optical communication track, actively researching and overcoming higher-performance optical communication laser chip technologies and process challenges, participating actively in data center DC construction, serving domestic and overseas customers, and helping to solve the industry's chip shortage.

In recent years, domestic optical communication companies have driven breakthroughs in some key core technologies and lead globally in applications, but the localization level of optical chips remains low. Changguang Huaxin is dedicated to the research, mass production, and sales of semiconductor laser chips, providing more choices for the communication industry.
