Anti rodent and ant fiber optic cable with bimetallic armor and nylon sheath (GYFTA54)

GYFTA54 is an outdoor communication optical cable composed of non-metallic central reinforcement elements, loose tube bundles, laminated aluminum tape armor, PE inner sheath, stainless steel tape armor, PE middle sheath, and nylon outer sheath. Single mode optical fibers are placed in loose tubes made of high modulus plastic and filled with grease. These pipes are wrapped around the central element to form a cable core. The cable core is filled with cable paste and armored with aluminum tape. Then extrude the PE inner sheath and armor it with stainless steel tape. Finally, extrude the PE inner sheath and nylon outer sheath.

Product Features
