GYJTA cable structure will be tight set of fiber surface placed aramid reinforcing elements and then squeeze jacket layer made of sub units, sub units and the center to strengthen with steel wire twisted to form a circular cable core, core cable around the waterstop, lapping and longitudinal wrapped a layer of coated aluminium and extruded into cable sheathing.

·Have very good mechanical properties and temperature characteristics.
·Good resistance and flexibility.
·Ability to withstand a variety of harsh environment in the field of long life, good toughness, tensile, ground.
·Adopt the following measures to ensure the waterproof performance of the optical cable.
  ·And the cable core is wrapped tightly with water blocking.
  ·longitudinal coated aluminium moistureproof layer.
  ·Good resistance to water to prevent leakage of optical fiber cables.

·GYJTA meets YD/T901-2009, and IEC60794-1 standards.
