GRT — Beijing Guang Run Tong Technology Development Co., Ltd. — is headquartered in Beijing’s Zhongguancun district, the technology quarter that grew around the capital’s universities and institutes. The company integrates research and development, production and marketing in one organisation, holds its own intellectual property and its own brand, and is recognised as a national high-tech enterprise and a Beijing "specialised and sophisticated" enterprise. Its R&D team is staffed by senior engineers, and the company’s products serve data centres, security systems, carriers and domestic-platform computing projects.
What GRT makes
The main lines are fiber and server network cards (gigabit to 100G, including OCP, bypass, encryption and domestic-controller models), optical transceiver modules, AOC/DAC high-speed cables, fiber patch cords, optical bypass equipment, CWDM/DWDM wavelength division equipment, media conversion, RAID and HBA cards, and FPGA-based custom development with OEM/ODM services. Three Ethernet controllers are the company’s own designs: the G810-2Q (100G), the G350AM2 (gigabit bypass) and the GRT-201JM (encryption).
Qualifications
Product and company qualifications held across the range include FCC, CE and RoHS product certifications and ISO 9001, ISO 14001 and ISO 45001 management system certifications, alongside domestic ecosystem verifications — including Kylin software NeoCertify product certification, UOS ecosystem partnership, and platform verification of selected adapters on Kunpeng, Phytium, Loongson and Zhaoxin platforms. The company also holds software copyrights and multiple patents. Certificates are available upon request.
