Flat FRP armored optical cable is a new type of optical cable structure that has functions such as strong electricity resistance, rodent resistance, and cicada resistance. Flat FRP is made of glass fiber and resin polymerization, and belongs to the category of glass fiber reinforced plastic wire. However, its cross-section is flat, and it has high tensile strength and hardness. It is used as an armor layer for optical cables, making it a fully dielectric optical cable with high mechanical strength, lightning resistance, and rodent resistance.
