Company overview
Established in 2002, Dongguan TW-SCIE Co., Ltd. is a comprehensive high-tech enterprise that integrates R&D, manufacture, sale of fiber optic communication products and network engineering. We have two manufacturing bases, one is in Donguan, Guangdong which occupies about 30000m2 with 20000m2 production factory, and the other is in Deyang, Sichuan which occupies 40000m2 with 20000m2 production factory. The annual production capacity of the two bases are 20 million core kilometers.
We are dedicated in R&D and application of fiber optic products and have obtained 5 invention patents and 58 utility model patents. The main products are indoor/outdoor fiber optic cable, ADSS, OPGW, FTTH drop cable, patch cord, pigtail and related accessories. The products conform to the China National Standard strictly and have obtained certificates of Anatel, CE, RoHs, Reach, ISO9001, ISO14004, OHSAS1801 and so on.
We boosts more than 300 staff as well as more than 50 sets of production and testing lines. Relying on advanced equipment, mature technology and good management, we always provide high quality products and best services to our customers. We are the qualified supplier to most of the famous communication companies in China such as China Mobile, China Telecom, China Unicom, Sinopec, State Grid, etc; at the same time, we have sold our products to Europe, Africa, Middle East, South America, Southwest of Asia and become the qualified supplier to the local telecom companies.
