GYTY53 Loose Tube Stranding Type Aerial Optical Cable
Structure features
  •Jelly-filled loose tube
  •Central metallic strength member 
  •Jelly-filled cable core
  •PE inner sheath
  •Laminated steel-plastic corrugated tape and PE outer sheath
Technology characteristics
  •Low loss,low chromatic dispersion
  •Special tube in tube technique makes cable excellent flexible
 capability and protection capability against bending.
  •Special excess-length control method and cabling mode makes
 optical cable good mechanical and environmental properties
  •Filling water-blocking jelly brings entirely cross section double
 water-blocking capability
  •Double sheaths can withstand great pressure.
The way of laying
Overhead, buried
