Filler

• A filler is a material used to fill spaces, maintain structure, and enhance the mechanical characteristics of a cable.
  The primary purposes are as follows:
  
  1) Filling internal spaces of the cable
  Fillers are used to occupy voids within the cable. This provides additional protection and reinforcement against external environmental factors, assisting in maintaining the cable's structure.
  
  2) Mechanical protection and reinforcement
  Fillers play a role in reinforcing and maintaining the structure of optical fiber cables. They enhance protection against external impacts and environmental conditions, helping the cable withstand bending and pressure.
  
  3) Maintaining the geometric shape of the cable
  Fillers are used inside optical communication cables to preserve the geometric shape of the cable and stabilize the position of the optical fibers. This is crucial for minimizing signal loss in optical communication systems and improving the overall performance of the cable.
  
  4) Heat conduction and insulation
  Some fillers possess heat-conductive or insulating properties, aiding in the stable maintenance of optical fiber cables at specific temperatures.
