GYFTY63 Optical Fiber Cable Loose Tube Laye Staranded Non-Metallic Heavy Type Rodent Protected
Fiber Count : 2 - 144
Tensile strength Long / Short term (N) : 600/2000 ~ 600 / 2500
Crush resistance / Long/Short term (N/100mm) : 300 / 1000
Bending radius / Static/Dynamic (mm) : 12.5D/25D
material, and the loose tube is filled with waterproof compound. The center of the cable core is a metallic Fiber
Reinforced Plastic (FRP)，for some cores fiber cable, a layer of polyethylene (PE) needs to be extruded outside
the metallic central strength member. The tubes (and filling rope) is stranded around the central reinforcing
core to form a compact and circular cable core. The gaps in the cable core are filled with water-blocking fillers,
and a layer of polyethylene (PE) inner sheath is extruded. After the glass yarns covered over the inner sheath,
the cable is completed with a PE outer sheath.
①Excellent mechanical property and temperature performance.
②Loose tube material has good hydrolysis resistance and higher intensity.
③Non-metallic central strength member FRP withstand axial loads.
④Inner sheath effectively lower the external mechanical loading.
⑤Glass yarn effectively prevents rodents from damaging optical fiber cable.
⑥PE sheath protects cable from ultraviolet radiation.
⑦Fully cable core filled.
