Loose tube layer twisted outdoor armored optical cable is manufactured by placing colored optical fiber cores within loose tubes, wrapping them with corrugated steel armor, inserting water-blocking tape between the armor and the tubes, and then extruding a PE outer sheath. This structure effectively protects the optical fibers from external forces and significantly enhances the cable's tensile and compressive strength. By selecting high-quality optical fibers, using specialized equipment, and employing reasonable process design, the product's performance exceeds the requirements of international standards such as ISO/IEC 11801. The product features high-quality performance, with performance metrics exceeding the requirements of standards such as ANSI/TIA-568.3-D, IEC 60794, and YD/T 901: the optical fiber characteristics meet and exceed the requirements of ITU-T G.561, ITU-T G.652.D, and IEC 60793 standards.
