Phosphated steel wire and fiber reinforced plastic (FRP) rods are both commonly used for optical cable strengthening, but they have different characteristics and applications.
Phosphated steel wire is a type of steel wire that has been treated with a phosphate coating to improve its corrosion resistance and adhesion to other materials. It is often used as a central strength member in optical fiber cables, providing mechanical support to the cable and helping to prevent it from stretching or breaking under tension.
FRP rods, on the other hand, are made of a composite material that typically consists of a fiberglass core surrounded by a protective resin layer. They are lightweight, strong, and corrosion-resistant, and are often used as a substitute for traditional steel wire in optical cables. FRP rods are particularly well-suited for use in harsh environments where corrosion and other types of damage are a concern.
Both phosphated steel wire and FRP rods are important components in the construction of optical fiber cables, and their specific applications will depend on the particular requirements of the project.
