GYTA53+333 Direct Buried Fiber Optic Cable 2-144 Cores Double Steel Wire Armored

Product Description

The structure of the optical cable is to insert single-mode or multi-mode optical fibers into a loose tube filled with waterproof compound made of high modulus plastic. At the center of the cable core is a metal reinforcing component. It includes metal reinforcing components, loose-fitting layer stranded filling type, aluminum-polyethylene bonded inner sheath, steel-polyethylene bonded inner sheath, double-layer round steel wire armor, and polyethylene outer sheath for communication. For some core numbers of optical cables, a polyethylene pad layer is extruded outside the metal central reinforcing element. Loose tubes (and filling ropes) are twisted around the central reinforcing element to form a compact and round cable core. The gaps inside the cable core are filled with water-blocking compound and extruded with an aluminum-polyethylene bonded inner sheath, followed by a steel-polyethylene bonded inner sheath. After being armored with double-layer fine round steel wires, the gaps are filled with water-blocking compound. The final polyethylene outer sheath is extruded to form the cable.

Youdaoplaceholder0 Laying methods: direct burial, underwater laying, climbing laying, marshland, etc.

Youdaoplaceholder0 Application scope: suitable for long-distance communication and inter-office communication, etc. It is generally laid underwater in deep water areas of > 100M and < 250M.

Youdaoplaceholder0 execution standard: YD/T 901-2018 outdoor optical cable for stranded communication.

Youdaoplaceholder0 Product features:

① Reasonable design and precise control of the excess length of the optical fiber in the loose tube and the cabling method endow the optical cable with excellent mechanical and environmental performance;

② The outside of the reinforcing parts and the inside of the cable core are filled with water-blocking cable paste, ensuring the moisture-proof and water-blocking effects of the optical cable.

③ The optical cable has excellent flexibility and resistance to bending.

④ The longitudinal wrapping of the cable core with metal tape makes the moisture-proof effect of the optical cable better and also gives it a certain compressive resistance capacity.

⑤ The double-layer steel wire armor layer endows the optical cable with better compressive and tensile strength.
