GYFTA53 Non-metallic Strength member Armored Fiber Cable /  Armored Fiber Optic Cable / Armored optical cable Product Description 
The GYFTA53 type optical cable places the 250um optical fiber in a loose sleeve made of high modulus plastic, and the sleeve is filled with waterproof filler. The center of the optical cable core is an FRP non-metallic reinforcement. The sleeve and the filler are twisted around the reinforcement to form a compact circular optical cable core. The optical cable core is covered with APL, the optical cable core is covered with a thin PE inner sheath, and the inner sheath is filled with waterproof glue. After the steel belt is armored, the PE outer sheath is added to form a cable.
