Developmental Timeline

Beijing Dacheng Yongsheng Technology Co., Ltd. began its operations in early 2013.

In July 2013, the precursor project team of the company pioneered the development of high-temperature-resistant optical cables for oil wells, advancing China's technology in cable logging.

In May 2014, the company was formally established.

In November 2014, the company simultaneously launched 150°C and 400°C high-temperature-resistant optical cables, enriching its product line in this field.

In January 2015, the 350°C high-temperature-resistant optical cable made a breakthrough in the oil field, gaining recognition under the name "Beijing Dacheng."

In November 2015, the company introduced vibration-sensitive optical cables, officially entering the field of security. This product represented another significant breakthrough for optical communication technology in the field of optical sensing.

In May 2016, the company obtained import and export qualifications from the Chinese Customs.

In June 2016, the company established a specialized optical cable prefabrication R&D and production base in Henan Province, China.

In February 2017, the company officially acquired the "Beinuo®" trademark.

In August 2017, the company launched stress-sensitive optical cables and three types of prefabricated optical cables for extreme harsh environments.

In March 2018, the company officially acquired the "Newfen®" trademark.

In September 2018, the company introduced Fiber Optic Grating Sensors and Distributed Fiber Optic Sensors.

In December 2018, the company officially obtained the "Maoxi®" trademark.

In April 2019, the company obtained utility model patents covering Fiber Optic Grating Sensors, Distributed Fiber Optic Sensors, and Fiber Optic Patch Cables.

In July 2019, the company officially acquired the "OFSCN®" and "PEINO®" trademarks.

In December 2019, the company obtained a second utility model patent covering Fiber Optic Grating Sensors, Distributed Fiber Optic Sensors, and Fiber Optic Patch Cables.

In March 2020, the company was identified as a "Zhongguancun High-tech Enterprise."

In May 2020, the company successfully listed on the Beijing Equity Exchange Incubation Board, enterprise code: ZS5150, abbreviated name: Dacheng Yongsheng.

In September 2021, the company officially obtained the third utility model patent covering Fiber Optic Grating Sensors. The patent is mainly used for strain measurement and serves as a measurement basis for various physical quantities based on strain.

In October 2021, the company officially obtained the fourth utility model patent covering Fiber Optic Grating Sensors. The patent is primarily used for temperature measurement in energized environments.

In November 2022, the company was invited to become an observer unit of the Optical Fiber Sensing Sub-Technical Committee of the National Optical and Photonics Standardization Technical Committee.

In January 2023, the company obtained the National Copyright Administration's Computer Software Copyright Certificate.
