24 fibers.
Zero metal.
Full lightning immunity.
The cost-smart choice for rural broadband, campus backbones, and FTTx feeder links.
GYFTY73 fiber opitc cable is suitable for area with strong electric filed and frequent thunderstorms.It consists of stranded loose tube, non metallic strength member(FRP), jelly compound, PE inner sheath, glass fiber strength member and PE outer sheath. It is suitable for duct, aerial and underground installation.
Entire Section Waterproof structure to ensure good water resistance properties
Loose tube filled with special jelly, a critical protection of fiber
Polyethylene (PE) sheath to ensure the cable has good UV resistance
Nonmetallic reinforcement with glass yarn, with some rodent performance
All-dielectric cable nonmetallic materials suitable for making strong electromagnetic fields and lightning-prone area
