Optical Cable Fiberglass Yarn: high performance and cheap.

If you are looking for a material that can reinforce your optical cable and protect it from water, moisture, and mechanical damage, you should consider using optical cable fiberglass yarn. This material has the following advantages and features:

High tensile strength and modulus：Optical cable fiberglass yarn is made of high-quality E-glass fibers that have a high tensile strength of 1200 MPa and a high modulus of 72 GPa. These properties make the yarn suitable for reinforcing optical cable cores and jackets, as well as providing axial strength and stiffness.
Low linear expansion coefficient and dielectric constant：Optical cable fiberglass yarn has a low linear expansion coefficient of 5.5 x 10^-6 /℃ and a low dielectric constant of 6.3. These properties make the yarn resistant to thermal stress and electromagnetic interference, which can affect the signal transmission and quality of optical cables.
Water-blocking and flame-retardant：Optical cable fiberglass yarn is coated with a special water-blocking agent that can swell when exposed to water or moisture, forming a gel-like layer that can block water penetration and prevent cable damage. The yarn is also treated with a flame-retardant agent that can reduce the flammability and smoke emission of optical cables in case of fire.
Cost-effective and eco-friendly：Optical cable fiberglass yarn is a cost-effective material that can reduce the weight and diameter of optical cables, saving material and transportation costs. The yarn is also eco-friendly, as it does not contain any harmful substances such as halogens, heavy metals, or asbestos.
