In this paper

all-dry flame-retardant PBT optical fiber cable for indoor and outdoor use is developed. The structure includes optical fiber and flame-retardant PBT sleeve which is set out the fiber. PBT tube has water-blocking yarn and water-blocking aramid fiber.The optical fiber adopt the whole dielectric material to make its whole cross section free of any metal components

and has natural shielding property. Flame-retardant PBT material which has high modulus

Shore hardness

low shrinkage

UV-resistant

flame retardant characteristics

on the one hand can improve the mechanical properties of products

on the other hand improve the product resistance UV and flame-retardant properties

so that it can meet the outdoor laying and indoor laying of the basic requirements.
