About Dagu
A Professional Optical Communication Supplier in China Optics Valley
Wuhan Dagu Intelligent Technology Co., Ltd. — our engineers have spent 16 years in optical R&D and manufacturing, and we deliver high-quality optical transceivers, fiber patch cords and network switches to customers worldwide.
Company Profile
Dagu Intelligent is headquartered in the Optics Valley of China — Wuhan East Lake High-Tech Zone — the world's largest fiber and cable production base and a world-class optoelectronics industrial cluster. From this location we operate inside a full industry chain covering fiber preforms, optical transceivers and laser equipment.
Our engineers have spent 16 years in optical communication R&D and manufacturing. Dagu Intelligent itself was registered in 2026, and today we supply a full-rate portfolio from 1.25G to 800G across SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD and OSFP form factors, alongside carrier-grade fiber patch cords, AOC / DAC assemblies and industrial plus enterprise network switches.
Customers come to us for three reasons: modules that are genuinely compatible with the equipment they already own, a supply chain that can respond quickly to small and mixed orders, and engineering support that continues after the shipment leaves our warehouse. We accept sample orders so you can verify performance on your own network before committing to volume.
