FRP Central Strength Member

We are able to supply FRP Central Strength Member for fiber optic cables from a reputable manufacturer in China to the MENA region.

FRP Central Strength Member, Insulation Rods are widely used all over the world in most types of optical fiber telecommunication and data cables. The up-to-date pultrusion technology is adopted for making FRP products, so the products have excellent properties.

1 Insensitive to the lightning strike, suitable for the area with frequent lightning and rain.
2 Free from the induction interference, can be laid and installed close to the power line and device.
3 No harmful gas, which will affect the transmission of the optical fiber, will be given off from the corrosive metal.
4 FRP Strength Member has a high ratio of strength/weight.
