GYTA53 Double Armored and Double Sheathed Stranded Outdoor Optical Cable,The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.

Features
 Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member
Loose tube filling compound and 100% cable core filling
APL moisture barrier
PSP enhancing moisture-proof
Water-blocking material
