High-strength aramid yarn and phosphatized steel wire can be used for optical fiber cable reinforcement. Aramid yarn is a high-performance synthetic fiber with excellent strength and durability, while phosphatized steel wire is a steel wire that has been treated with a special phosphate coating to improve its bonding and adhesion properties. When used together, they can provide enhanced mechanical strength and stability to optical fiber cables, allowing them to withstand the rigors of installation and use in harsh environments.
