Wuxi Dobest is specialized in high-tech nonmetallic reinforced core for optical cable---FRP, the crystallization of high-tech, high starting point and Chinese new industry. Having adequately exerted the advantages in capital and technology since founded, the company has developed and produced all sizes and models of products from φ0.4-φ4.5MM. The 13 projects tested by national authoritative institutes (example: WRI, SECRI, etc.) all accord with and exceed every technical index of national standard (YD/T1181.1-2002), reaching national leading level. In the past, it was used to adopt phosphating steel wire as reinforced core to produce optical cable in home. But with the quick development of science and technology, the original material (steel wire) shall be substituted by new functional material (FRP).
