Direct Bury Fiber Optic Cable GYFTA53 FRP Loose Tube

The structure of GYFTA53 direct bury fiber optic cable mainly includes outer sheath, inner sheath, steel strip, aluminum strip, cable paste, loose tube, optical fiber and other materials. Fiber optics can choose single-mode or multi-mode structures. The cable core center is a non-metallic reinforced core. For some fiber optic cables, a layer of polyethylene (PE) is extruded inside the non-metallic reinforced core. The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core. The inside and outside of the optical cable are both covered with PE sheath, which provides certain protection for the optical cable.
