With the development of optical communication, the requirement of optical fiber cable to environmental performance is higher. In this paper, a kind of high-strength and high toughness fiber bundle tube material is introduced, and suitable extrusion process is adopted. Combined with the production process optimization. The fiber bundle tube produced by this material has good strength and flexural properties, which makes the whole fiber optic cable have better mechanical and environmental properties than that of the fiber bundle of PBT or PP material. The results show that the application of this material is promising.
