Product Structure


  1. Special composite material loose casing to reduce low temperature casing retraction;
  2. The remaining length of the optical fiber is precisely controlled and the performance of the optical cable is stable;
  3. Unique process control prevents the sheath from wrinkling during air blowing;
  4. High-density polyethylene outer sheath to increase air blowing distanc
