Aerial Fiber Optic Cable

1. Brief introduction of optical fiber cables   GYTC8S: Metallic strength member, Loose tube stranded and filled with jelly, Corrugated steel tape, Outer PE sheath,  3.0mm galvanized stranded steel wire. Self supporting type optical cable for outdoor.   Application: JINLONG Figure-8 cables are self-supporting cable designed for aerial installation. The cable design provides easy and economical one-step installation and stable performance over a wide temperature range and is compatible with any telecommunication grade optical fiber. Design： l Up to 288 fibers l Low attenuation, low dispersion, stable control of excess length makes the optical cable perfect mechanical and environmental properties.  l As a self-supporting design, easy and one-step installation,using standard hardware and working methods  l Designed in accordance with applicable industry technical specifications, standards and references including IEC and EN   2. Cable Construction 2.1 Cable cross-section Figure 1 cross-section of GYTC8S   3.  Cable Specification   3.1 Sheath marking  GYTC8S  24C  G652D   JLGD  2014  XXXX M   JLGD   : Manufacturer’s brand(we can design as per client brand) 2014 : Manufacture year GYTC8S : Cable type 24C G652D : XX cores single-mode optical fiber (ITU-T Rec.
