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 an>. 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

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. G.652D) |
XXXXm | : Mark of meters |
*The marking is printed every 1 meter; **â€G.652D†means ITU-T Rec. Low Water Peak (LWP) G.652D Single Mode Optical Fiber. | |
3.2 The color of marking is white, but if the remarking is necessary, the yellow color marking shall be printed newly on a different position.
3.3 An occasional unclear of length marking is permitted if both of the neighboring markings are clear;
3.4 The both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
