Milestone

Since its establishment in 2019, Qstar-Link Optical Technology Co.,Ltd. has always adhered to a development strategy centered on technology and guided by the market, conducting continuous strategic layout and resource integration.

In 2019
In May 2019, Qstar-Link Optical Technology Co., Ltd.was officially established in Longhua District, Shenzhen, China. This establishment marks the company's anchoring in the high-end optical interconnect field and the beginning of a journey driven by technological innovation for development.
In September 2020, in response to the growing demand for high-speed active optical cable (AOC) components in the market, the company established a dedicated AOC component production factory in Dongguan, Guangdong. The production of this factory has significantly enhanced the company's ability to manufacture and deliver active optical interconnect products on a large scale, laying a solid foundation for serving core markets such as data centers.
In 2021
In June 2021, in order to further expand its product line and application scenarios, the company established a production base focused on outdoor waterproof connectors in Heyuan, Guangdong. The establishment of this factory enables the company to provide customers with high reliability fiber optic connection solutions suitable for harsh environments, successfully entering emerging market areas such as 5G fronthaul and outdoor network construction.
In 2025
In May 2025, in order to optimize production layout and strengthen synergies, the company will consolidate the production resources of the core product of multi-core connectors to its headquarters in Longhua, Shenzhen. This integration has improved the efficiency and flexibility of production management, providing strong guarantees for quality control and capacity improvement of core products.
In July 2025, the company officially established a high-level research and development center and optical laboratory at its headquarters in Longhua, Shenzhen. This move marks a new stage in the company's technological innovation system. The R&D center will not only focus on the independent development of cutting-edge products, but also initiate deep cooperation with many top domestic research institutes and institutions, aiming to jointly tackle key technologies of next-generation optical interconnection and continuously consolidate the company's technological leadership position.

Quality control

Executable, traceable, and continuously optimizable standardized processes to establish a "Multi-Level Closed-Loop Quality Control System".

Design prevention

During the R&D phase, cross departmental reviews and risk prevention are implemented to complete comprehensive reliability verification of optics, mechanics, and environment, ensuring that the design meets the standards at the source.

Strictly control incoming materials

Establish a quality data sharing mechanism with core suppliers, perform quantitative testing and small batch certification of incoming materials, and ensure consistency from the material end.

Process standards

Quality control points are set up for key processes, using statistical process control techniques, combined with first article inspection and online inspection to ensure stable and controlled manufacturing.

Reliable verification

The finished product undergoes 100% optical performance testing, and high-end products undergo accelerated aging testing to ensure both performance and long-term reliability meet the standards.

Quick response

Respond to customer feedback within 24 hours, initiate root cause analysis, develop corrective and preventive measures, and prevent problem recurrence.

System evolution

Aggregate quality data throughout the entire process, regularly analyze and review, drive process optimization and standard upgrades, and achieve continuous iteration of the quality control system.
