Committed to building a product R&D center and manufacturer with international industry status.
After months of rigorous testing and auditing, on November 20, 2023, Dugan core VCSEL chip series products - Dongfanghong successfully passed the AEC-Q102 automotive certification. At the same time, Du Gen Tianyuan Company also passed the IATF16949 quality system certification this month. AEC-Q102 automotive-grade product qualification and IATF16949 quality system qualification are two passports to enter the automotive electronics industry. In this regard, the core core will accelerate the focus on the layout of the automotive industry.
In November 23, the company passed the IATF16949 quality system certification, and the introduction and certification of the system marked that the company has the product supply capacity and qualification in the field of automotive lidar applications in the automotive industry.
From November 15th to 16th, 2023, the the 2023 World Optical Communications Congresswas successfully held at Buckingham Hotel in Suzhou! Dogain was invited to participate in the conference and comprehensively demonstrated single-mode 980nm optical communication products and technologies during the conference.
