GYTS cable is designed for outdoor FTTx cabling system and underground network construction. The outer sheath of GYTS cable is made of durable polyethylene (PE) material, which has the anti-mouse bite, water-proof functions. Inside the cable, there are loose tubes holding 250μm cladding fibers. Quantities of Fiber at each bunch can be customized. There are filling gel among fiber bunches to protect fiber against water and let fiber can be easily pulled. At the core of GYTS cable is metallic strength member, which are used for easily pulled which outdoor cabling system needing to drive the cable. Loose tube equips good water-proof performance and high strength with special compound gel, all these provide key protect to inside fibers.


  • Meet YD/T 901-2001as and IEC 60794-1 standard
  •  Good mechanical and ductility performance at cold weather
  •  Solid PE sheath equips water-proof and anti-mouse bite function
  •  Corning G652D or G657A1 fiber for chosen
  •  Compact cable structure against any shake at transportation and damage
  •  Strong metallic central strength member
  •  Full lubrication gel filling fiber bunch
  • Moisture-proof
