Optical fibers, loose tube construction, tubes jelly filled, elements (tubes and filler rods) laid up around metallic central strength member(steel wire), filling compound filled in the apertures of the cable core, synthetic wrapping yarns, polymer coated corrugated steel tape as moisture barrier (GYTC8S)/polymer coated aluminum tape as moisture barrier(GYTC8A)/without any tape(GYTC8Y), PE outer sheath and messenger wires combined.
Characteristics:
I. Selection of high-quality optical fiber, optical cable that has an excellent transmission performance
II. Precise control over long optical fiber, optical cable has an excellent guarantee that the mechanical properties and temperature characteristics
III. Rigorous process and raw materials control and ensure stability of fiber optic cable over 30 years.
IIII. Water blocking the entire cross-section structure, to ensure good water blocking moisture resistant
V. Casing filled with special ointment, a critical protection of the fiber
VI. Longitudinal with Baotou Steel to strengthen the anti-lateral pressure cable capacity
VII. 8 fonts Self-supporting structure of high tensile strength, to facilitate the laying of overhead, lower installation costs

Applications: Long distance and interoffice communication
Laying mode: Aerial
Opterating temperature: -40º C~+70º C
Hanging line: 1.2 X 7, 1.5 X 7 structure Strand, it can be designed according to clients.
PS: 1)The steel wire centre strength member can be changed into FRP strength member.
2)Add "F" letter means the central strength member is FRP, nonmetalic way.
