Metallic strength member, loose tube stranded, aluminum-polyethylene jellied inner sheath, PSP-PE jellied outer sheath, and communication optical fiber cable outdoors.

Applications: Used in duct and directly buried.

Advantages:
(1) Many subunits increase the fiber density;
(2) Unique strand technics increases good mechanical and environmental performance;
(3) Aluminum-polyethene inner sheath increases the moisture-proof performance;
(4) Corrugated Steel-plastic compound belt greatly increases the crush, tensile, and moisture-proof performance.
